NAME

find — find files

SYNOPSIS

find [-H|-L] path... [operand_expression...]

DESCRIPTION

The find utility shall recursively descend the directory hierarchy from each file specified by path, evaluating a Boolean expression composed of the primaries described in the OPERANDS section for each file encountered. Each path operand shall be evaluated unaltered as it was provided, including all trailing <slash> characters; all pathnames for other files encountered in the hierarchy shall consist of the concatenation of the current path operand, a <slash> if the current path operand did not end in one, and the filename relative to the path operand. The relative portion shall contain no dot or dot-dot components, no trailing <slash> characters, and only single <slash> characters between pathname components.

The find utility shall be able to descend to arbitrary depths in a file hierarchy and shall not fail due to path length limitations (unless a path operand specified by the application exceeds {PATH_MAX} requirements).

The find utility shall detect infinite loops; that is, entering a previously visited directory that is an ancestor of the last file encountered. When it detects an infinite loop, find shall write a diagnostic message to standard error and shall either recover its position in the hierarchy or terminate. In either case, the final exit status shall be non-zero.

If a file is removed from or added to the directory hierarchy being searched it is unspecified whether or not find includes that file in its search.

OPTIONS

The find utility shall conform to XBD 12.2 Utility Syntax Guidelines.

The following options shall be supported by the implementation:

-H

Cause the file information and file type evaluated for each symbolic link encountered as a path operand on the command line to be those of the file referenced by the link, and not the link itself. If the referenced file does not exist, the file information and type shall be for the link itself. File information and type for symbolic links encountered during the traversal of a file hierarchy shall be that of the link itself.

-L

Cause the file information and file type evaluated for each symbolic link encountered as a path operand on the command line or encountered during the traversal of a file hierarchy to be those of the file referenced by the link, and not the link itself. If the referenced file does not exist, the file information and type shall be for the link itself.

Specifying more than one of the mutually-exclusive options -H and -L shall not be considered an error. The last option specified shall determine the behavior of the utility. If neither the -H nor the -L option is specified, then the file information and type for symbolic links encountered as a path operand on the command line or encountered during the traversal of a file hierarchy shall be that of the link itself.

OPERANDS

The following operands shall be supported:

The first operand and subsequent operands up to but not including the first operand that starts with a '-', or is a '!' or a '(', shall be interpreted as path operands. If the first operand starts with a '-', or is a '!' or a '(', the behavior is unspecified. Each path operand is a pathname of a starting point in the file hierarchy.

The first operand that starts with a '-', or is a '!' or a '(', and all subsequent arguments shall be interpreted as an expression made up of the following primaries and operators. In the descriptions, wherever n is used as a primary argument, it shall be interpreted as a decimal integer optionally preceded by a <plus-sign> ('+') or <hyphen-minus> ('-'), as follows:

+n

More than n.

n

Exactly n.

-n

Less than n.

The following primaries shall be supported:

-name pattern

The primary shall evaluate as true if the basename of the current pathname matches pattern using the pattern matching notation described in 2.14 Pattern Matching Notation. The additional rules in 2.14.3 Patterns Used for Filename Expansion do not apply as this is a matching operation, not an expansion.

-iname pattern

The -iname primary shall be equivalent to -name, except that the match shall be case insensitive. See XBD 4.1 Case Insensitive Comparisons.

-path pattern

The primary shall evaluate as true if the current pathname matches pattern using the pattern matching notation described in 2.14 Pattern Matching Notation. The additional rules in 2.14.3 Patterns Used for Filename Expansion do not apply as this is a matching operation, not an expansion.

-nouser

The primary shall evaluate as true if the file belongs to a user ID for which the getpwuid() function defined in the System Interfaces volume of POSIX.1-2024 (or equivalent) returns NULL.

-nogroup

The primary shall evaluate as true if the file belongs to a group ID for which the getgrgid() function defined in the System Interfaces volume of POSIX.1-2024 (or equivalent) returns NULL.

-mount

The primary shall always evaluate as true; it shall cause find to act only on files that have the same device ID (st_dev, see XSH fstatat) as the path operand below which they are encountered and cause find not to descend below directories that have a different device ID than that path operand. If any -mount primary is specified, it shall apply to the entire expression even if the -mount primary would not normally be evaluated.

-xdev

The primary shall always evaluate as true; it shall cause find not to descend below directories that have a different device ID (st_dev, see XSH fstatat) than the path operand below which they are encountered; that is, when a directory with a different device ID is encountered, find shall act on the directory itself (unless -mount is specified) but shall not act on any files below the directory. If any -xdev primary is specified, it shall apply to the entire expression even if the -xdev primary would not normally be evaluated.

-prune

The primary shall always evaluate as true; it shall cause find not to descend the current pathname if it is a directory. If the -depth primary is specified, the -prune primary shall have no effect.

-perm [-]mode

The mode argument is used to represent file mode bits. It shall be processed in an identical manner to the symbolic_mode operand described in chmod, except that:

1. The changes to file mode bits shall be applied to a template instead of to any files. The template shall initially have all file mode bits cleared.

2. The op symbol '-' cannot be the first character of mode; this avoids ambiguity with the optional leading <hyphen-minus>. Since the initial mode is all bits off, there are not any symbolic modes that need to use '-' as the first character.

If the <hyphen-minus> is omitted, the primary shall evaluate as true when the file permission bits exactly match the value of the resulting template.

Otherwise, if mode is prefixed by a <hyphen-minus>, the primary shall evaluate as true if at least all the bits in the resulting template are set in the file permission bits.

-perm [-]onum

If the <hyphen-minus> is omitted, the primary shall evaluate as true when the file mode bits exactly match the value of the octal number onum (see the description of the octal mode in chmod). Otherwise, if onum is prefixed by a <hyphen-minus>, the primary shall evaluate as true if at least all of the bits specified in onum are set. In both cases, the behavior is unspecified when onum exceeds 07777.

-type c

The primary shall evaluate as true if the type of the file is c, where c is 'b', 'c', 'd', 'l', 'p', 'f', or 's' for block special file, character special file, directory, symbolic link, FIFO, regular file, or socket, respectively.

-links n

The primary shall evaluate as true if the file has n links.

-user uname

The primary shall evaluate as true if the file belongs to the user uname. If uname is a decimal integer and the getpwnam() (or equivalent) function does not return a valid user name, uname shall be interpreted as a user ID.

-group gname

The primary shall evaluate as true if the file belongs to the group gname. If gname is a decimal integer and the getgrnam() (or equivalent) function does not return a valid group name, gname shall be interpreted as a group ID.

-size n[c]

The primary shall evaluate as true if the file size in bytes, divided by 512 and rounded up to the next integer, is n. If n is followed by the character 'c', the size shall be in bytes.

-atime n

The primary shall evaluate as true if the file access time subtracted from the initialization time, divided by 86400 (with any remainder discarded), is n.

-ctime n

The primary shall evaluate as true if the time of last change of file status information subtracted from the initialization time, divided by 86400 (with any remainder discarded), is n.

-mtime n

The primary shall evaluate as true if the file modification time subtracted from the initialization time, divided by 86400 (with any remainder discarded), is n.

-exec utility_name [argument ...] ;

-exec utility_name [argument ...]  {} +

The end of the primary expression shall be punctuated by a <semicolon> or by a <plus-sign>. Only a <plus-sign> that immediately follows an argument containing only the two characters "{}" shall punctuate the end of the primary expression. Other uses of the <plus-sign> shall not be treated as special.

If the primary expression is punctuated by a <semicolon>, the utility utility_name shall be invoked once for each pathname and the primary shall evaluate as true if the utility returns a zero value as exit status. A utility_name or argument containing only the two characters "{}" shall be replaced by the current pathname. If a utility_name or argument string contains the two characters "{}", but not just the two characters "{}", it is implementation-defined whether find replaces those two characters or uses the string without change.

If the primary expression is punctuated by a <plus-sign>, the primary shall always evaluate as true, and the pathnames for which the primary is evaluated shall be aggregated into sets. The utility utility_name shall be invoked once for each set of aggregated pathnames. Each invocation shall begin after the last pathname in the set is aggregated, and shall be completed before the find utility exits and before the first pathname in the next set (if any) is aggregated for this primary, but it is otherwise unspecified whether the invocation occurs before, during, or after the evaluations of other primaries. If any invocation returns a non-zero value as exit status, the find utility shall return a non-zero exit status. An argument containing only the two characters "{}" shall be replaced by the set of aggregated pathnames, with each pathname passed as a separate argument to the invoked utility in the same order that it was aggregated. The size of any set of two or more pathnames shall be limited such that execution of the utility does not cause the system's {ARG_MAX} limit to be exceeded. If more than one argument containing the two characters "{}" is present, the behavior is unspecified.

The current directory for the invocation of utility_name shall be the same as the current directory when the find utility was started. If the utility_name names any of the special built-in utilities (see 2.15 Special Built-In Utilities), the results are undefined.

-ok utility_name [argument ...] ;

The -ok primary shall be equivalent to -exec, except that the use of a <plus-sign> to punctuate the end of the primary expression need not be supported, and find shall request affirmation of the invocation of utility_name using the current file as an argument by writing to standard error as described in the STDERR section. If the response on standard input is affirmative, the utility shall be invoked. Otherwise, the command shall not be invoked and the value of the -ok operand shall be false.

-print

The primary shall always evaluate as true; it shall cause the current pathname to be written to standard output, followed by a <newline>.

-print0

The primary shall always evaluate as true; it shall cause the current pathname to be written to standard output, followed by a null byte.

-newer file

The primary shall evaluate as true if the modification time of the current file is more recent than the modification time of the file named by the pathname file. If file names a symbolic link, the modification time used shall be that of the file referenced by the symbolic link if either the -H or -L option is specified; if neither -H nor -L is specified, it is unspecified whether the modification time is that of the symbolic link itself or of the file referenced by the symbolic link. In either case, if the referenced file does not exist, the modification time used shall be that of the link itself. If file is a relative pathname, it shall be resolved relative to the current working directory that was inherited by find when it was invoked.

-depth

The primary shall always evaluate as true; it shall cause descent of the directory hierarchy to be done so that all entries in a directory are acted on before the directory itself. If a -depth primary is not specified, all entries in a directory shall be acted on after the directory itself. If any -depth primary is specified, it shall apply to the entire expression even if the -depth primary would not normally be evaluated.

The primaries can be combined using the following operators (in order of decreasing precedence):

( expression )

True if expression is true.

! expression

Negation of a primary; the unary NOT operator.

expression [-a] expression

Conjunction of primaries; the AND operator is implied by the juxtaposition of two primaries or made explicit by the optional -a operator. The second expression shall not be evaluated if the first expression is false.

expression -o expression

Alternation of primaries; the OR operator. The second expression shall not be evaluated if the first expression is true.

If no expression is present, -print shall be used as the expression. Otherwise, if the given expression does not contain any of the primaries -exec, -ok, or -print, the given expression shall be effectively replaced by:

( given_expression ) -print

The -user, -group, and -newer primaries each shall evaluate their respective arguments only once.

When the file type evaluated for the current file is a symbolic link, the results of evaluating the -perm primary are implementation-defined.

STDIN

If the -ok primary is used, the response shall be read from the standard input. An entire line shall be read as the response. Otherwise, the standard input shall not be used.

INPUT FILES

None.

ENVIRONMENT VARIABLES

The following environment variables shall affect the execution of find:

LANG

Provide a default value for the internationalization variables that are unset or null. (See XBD 8.2 Internationalization Variables for the precedence of internationalization variables used to determine the values of locale categories.)

LC_ALL

If set to a non-empty string value, override the values of all the other internationalization variables.

LC_COLLATE

Determine the locale for the behavior of ranges, equivalence classes, and multi-character collating elements used in the pattern matching notation for the -name, -iname, and -path primaries and in the extended regular expression defined for the yesexpr locale keyword in the LC_MESSAGES category.

LC_CTYPE

This variable determines the locale for the interpretation of sequences of bytes of text data as characters (for example, single-byte as opposed to multi-byte characters in arguments), the behavior of character classes within the pattern matching notation used for the -name, -iname, and -path primaries, and the behavior of character classes within regular expressions used in the extended regular expression defined for the yesexpr locale keyword in the LC_MESSAGES category.

LC_MESSAGES

Determine the locale used to process affirmative responses, and the locale used to affect the format and contents of diagnostic messages and prompts written to standard error.

NLSPATH

^[XSI] Determine the location of messages objects and message catalogs.

PATH

Determine the location of the utility_name for the -exec and -ok primaries, as described in XBD 8. Environment Variables.

ASYNCHRONOUS EVENTS

Default.

STDOUT

The -print primary shall cause the current pathname to be written to standard output. The format shall be:

"%s\n", <path>

The -print0 primary shall cause the current pathname to be written to standard output, followed by a null byte.

STDERR

The -ok primary shall write a prompt to standard error containing at least the utility_name to be invoked and the current pathname. In the POSIX locale, the last non-<blank> in the prompt shall be '?'. The exact format used is unspecified.

Otherwise, the standard error shall be used only for diagnostic messages.

OUTPUT FILES

None.

EXTENDED DESCRIPTION

None.

EXIT STATUS

The following exit values shall be returned:

 0

All path operands were traversed successfully, the output (if any) specified in STDOUT was successfully written to standard output, and all commands (if any) executed using the -exec primary punctuated by a <plus-sign> exited with exit status 0.

>0

A command executed using the -exec primary punctuated by a <plus-sign> exited with non-zero status, or an error occurred.

CONSEQUENCES OF ERRORS

Default.

APPLICATION USAGE

When used in operands, pattern matching notation, <semicolon>, <left-parenthesis>, and <right-parenthesis> characters are special to the shell and must be quoted (see 2.2 Quoting ).

When restricting the search to files on one file system, it can sometimes be desirable for the crossing points themselves to be acted on and sometimes for them not to be acted on. (Crossing points are mount points and, if the -L option is specified, symbolic links to directories on other file systems.) The -xdev primary acts on them and the -mount primary does not. However, -mount also does not act on symbolic links to non-directory files on other file systems (if -L is specified). If there is a need for an application to exclude crossing points but include symbolic links to non-directory files on other file systems, this can be achieved by using two find commands as follows:

find -L dir -mount -type d -print
find -L dir -xdev ! -type d -print

(in a subshell whose output is piped to sort, if the order matters).

If both -mount and -xdev are specified, find obeys both primaries but the end result is the same as if -xdev were not specified.

The bit that is traditionally used for sticky (historically 01000) is specified in the -perm primary using the octal number argument form. Since this bit is not defined by this volume of POSIX.1-2024, applications must not assume that it actually refers to the traditional sticky bit.

EXAMPLES

1. The following commands are equivalent:

   find .
   find . -print
   

   They both write out the entire directory hierarchy from the current directory.

   With this output format, if any pathnames include <newline> characters, it is not possible to tell where each pathname begins and ends. This problem can be avoided by omitting such pathnames:

   LC_ALL=POSIX find . -name $'*\n*' -prune -o -print
   

   or by using a sentinel in the pathname that find would never otherwise produce, such as:

   find .//. -print
   

   or by using -print0 instead of -print and processing the output with a utility that can accept null-terminated pathnames as input, such as xargs with the -0 option or read with -d "", for example:

   find . -print0 | while IFS= read -rd "" file
   do
       # process "$file"
   done
   

   It should be noted that using find with -print0 to pipe input to xargs -r0 is less safe than using find with -exec because if find -print0 is terminated after it has written a partial pathname, the partial pathname may be processed as if it was a complete pathname.

2. The following command:

   find / \( -name tmp -o -name '*.xx' \) ! -type d -mtime +7 \
       -exec rm {} +
   

   removes all files named tmp or ending in .xx that have not been modified for more than seven (that is, eight or more) 24-hour periods.

3. The following command:

   find . -perm -o+w,+s
   

   prints (-print is assumed) the names of all files in or below the current directory, with all of the file permission bits S_ISUID, S_ISGID, and S_IWOTH set, regardless of the value of the file creation mask. (Note that the file creation mask is only specified for the file permission bits, and not S_ISUID, S_ISGID or S_ISVTX.)

4. The following command:

   find . -perm -+w
   

   prints (-print is assumed) the names of all files in or below the current directory, with S_IWUSR set if the file creation mask does not have S_IWUSR set (otherwise the S_IWUSR bit is ignored), S_IWGRP set if the file creation mask does not have S_IWGRP set (otherwise S_IWGRP is ignored), and S_IWOTH set if the file creation mask does not have S_IWOTH set (otherwise S_IWOTH is ignored).

5. The following command:

   find . -name SCCS -prune -o -print
   

   recursively prints pathnames of all files in the current directory and below, but skips directories named SCCS and files in them.

6. The following command:

   find . -print -name SCCS -prune
   

   behaves as in the previous example, but prints the names of the SCCS directories.

7. The following command is roughly equivalent to the -nt extension to test:

   if [ -n "$(find file1 -prune -newer file2)" ]; then
       printf %s\\n "file1 is newer than file2"
   fi
   

8. The descriptions of -atime, -ctime, and -mtime use the terminology n "86400 second periods (days)". For example, a file accessed at 23:59 is selected by:

   find . -atime -1 -print
   

   at 00:01 the next day (less than 24 hours later, not more than one day ago); the midnight boundary between days has no effect on the 24-hour calculation.

9. The following command:

   find . ! -name . -prune -name '*.old' -exec \
       sh -c 'mv "$@" ../old/' sh {} +
   

   performs the same task as:

   mv ./*.old ./.old ./.*.old ../old/
   

   while avoiding an "Argument list too long" error if there are a large number of files ending with .old and without running mv if there are no such files (and avoiding "No such file or directory" errors if ./.old does not exist or no files match ./*.old or ./.*.old).

   The alternative:

   find . ! -name . -prune -name '*.old' -exec mv {} ../old/ \;
   

   is less efficient if there are many files to move because it executes one mv command per file.

10. On systems configured to mount removable media on directories under /media, the following command searches the file hierarchy for files of size larger than 100000 KiB without searching any mounted removable media:

    find / -path /media -prune -o -size +200000 -print
    

11. Except for the root directory, and "//" on implementations where "//" does not refer to the root directory, no pattern given to -name will match a <slash>, because trailing <slash> characters are ignored when computing the basename of the file under evaluation. Given two empty directories named foo and bar, the following command:

    find foo/// bar/// -name foo -o -name 'bar?*'
    

    prints only the line "foo///".

RATIONALE

The -a operator was retained as an optional operator for compatibility with historical shell scripts, even though it is redundant with expression concatenation.

The descriptions of the '-' modifier on the mode and onum arguments to the -perm primary agree with historical practice on BSD and System V implementations. System V and BSD documentation both describe it in terms of checking additional bits; in fact, it uses the same bits, but checks for having at least all of the matching bits set instead of having exactly the matching bits set.

The exact format of the interactive prompts is unspecified. Only the general nature of the contents of prompts are specified because:

• Implementations may desire more descriptive prompts than those used on historical implementations.

• Since the historical prompt strings do not terminate with <newline> characters, there is no portable way for another program to interact with the prompts of this utility via pipes.

Therefore, an application using this prompting option relies on the system to provide the most suitable dialog directly with the user, based on the general guidelines specified.

The -size operand refers to the size of a file, rather than the number of blocks it may occupy in the file system. The intent is that the st_size field defined in the System Interfaces volume of POSIX.1-2024 should be used, not the st_blocks found in historical implementations. There are at least two reasons for this:

1. In both System V and BSD, find only uses st_size in size calculations for the operands specified by this volume of POSIX.1-2024. (BSD uses st_blocks only when processing the -ls primary.)

2. Users usually think of file size in terms of bytes, which is also the unit used by the ls utility for the output from the -l option. (In both System V and BSD, ls uses st_size for the -l option size field and uses st_blocks for the ls -s calculations. This volume of POSIX.1-2024 does not specify ls -s.)

The descriptions of -atime, -ctime, and -mtime were changed from the SVID description of n "days" to n being the result of the integer division of the time difference in seconds by 86400. The description is also different in terms of the exact timeframe for the n case (versus the +n or -n), but it matches all known historical implementations. It refers to one 86400 second period in the past, not any time from the beginning of that period to the current time. For example, -atime 2 is true if the file was accessed any time in the period from 72 hours to 48 hours ago.

Historical implementations do not modify "{}" when it appears as a substring of an -exec or -ok utility_name or argument string. There have been numerous user requests for this extension, so this volume of POSIX.1-2024 allows the desired behavior. At least one recent implementation does support this feature, but encountered several problems in managing memory allocation and dealing with multiple occurrences of "{}" in a string while it was being developed, so it is not yet required behavior.

Assuming the presence of -print was added to correct a historical pitfall that plagues novice users, it is entirely upwards-compatible from the historical System V find utility. In its simplest form (find directory), it could be confused with the historical BSD fast find. The BSD developers agreed that adding -print as a default expression was the correct decision and have added the fast find functionality within a new utility called locate.

Historically, the -L option was implemented using the primary -follow. The -H and -L options were added for two reasons. First, they offer a finer granularity of control and consistency with other programs that walk file hierarchies. Second, the -follow primary always evaluated to true. As they were historically really global variables that took effect before the traversal began, some valid expressions had unexpected results. An example is the expression -print -o -follow. Because -print always evaluates to true, the standard order of evaluation implies that -follow would never be evaluated. This was never the case. Historical practice for the -follow primary, however, is not consistent. Some implementations always follow symbolic links on the command line whether -follow is specified or not. Others follow symbolic links on the command line only if -follow is specified. Both behaviors are provided by the -H and -L options, but scripts using the current -follow primary would be broken if the -follow option is specified to work either way.

Since the -L option resolves all symbolic links and the -type l primary is true for symbolic links that still exist after symbolic links have been resolved, the command:

find -L . -type l

prints a list of symbolic links reachable from the current directory that do not resolve to accessible files.

A feature of SVR4's find utility was the -exec primary's + terminator. This allowed filenames containing special characters (especially <newline> characters) to be grouped together without the problems that occur if such filenames are piped to xargs.

The "-exec ... {} +" syntax adopted was a result of IEEE PASC Interpretation 1003.2 #210. It should be noted that this is an incompatible change to IEEE Std 1003.2-1992. For example, the following command printed all files with a '-' after their name if they are regular files, and a '+' otherwise:

find / -type f -exec echo {} - ';' -o -exec echo {} + ';'

The change invalidates usage like this. Even though the previous standard stated that this usage would work, in practice many did not support it and the standard developers felt it better to now state that this was not allowable.

Historically, many find implementations supported -mount and -xdev as synonymous primaries and earlier versions of this standard only required support for -xdev. However, the behavior of find with -xdev differed from that of the nftw() function with FTW_MOUNT as regards whether the mount point itself was included or excluded. Therefore the standard now requires support for both primaries with slightly differing behaviors: -mount behaves in the manner of nftw() with the traditional FTW_MOUNT flag, and -xdev in the manner of nftw() with a new FTW_XDEV flag.

FUTURE DIRECTIONS

If this utility is directed to display a pathname that contains any bytes that have the encoded value of a <newline> character when <newline> is a terminator or separator in the output format being used, implementations are encouraged to treat this as an error. A future version of this standard may require implementations to treat this as an error.
