sact - print current SCCS file-editing activity (DEVELOPMENT)
The sact utility informs the user of any impending deltas to a named SCCS file by writing a list to standard output. This situation occurs when get -e has been executed previously without a subsequent execution of delta.
The following operand is supported:
- A pathname of an existing SCCS file or a directory. If file is a directory, sact behaves as though each file in the directory were specified as a named file, except that non-SCCS files (last component of the pathname does not begin with s.) and unreadable files are silently ignored. If a single instance file is specified as -, the standard input is read; each line of the standard input is taken to be the name of an SCCS file to be processed. Non-SCCS files and unreadable files are silently ignored.
The standard input is a text file used only when the file operand is specified as -. Each line of the text file is interpreted as an SCCS pathname.
Any SCCS files interrogated are files of an unspecified format.
The following environment variables affect the execution of sact:
- Provide a default value for the internationalisation variables that are unset or null. If LANG is unset or null, the corresponding value from the implementation-dependent default locale will be used. If any of the internationalisation variables contains an invalid setting, the utility will behave as if none of the variables had been defined.
- If set to a non-empty string value, override the values of all the other internationalisation variables.
- Determine the locale for the interpretation of sequences of bytes of text data as characters (for example, single- as opposed to multi-byte characters in arguments and input files).
- Determine the locale that should be used to affect the format and contents of diagnostic messages written to standard error.
- Determine the location of message catalogues for the processing of LC_MESSAGES .
The output for each named file consists of a line in the following format:
"%s%s%s%s%s\n", <SID>, <new SID>, <login>, <date>, <time>
- Specifies the SID of a delta that currently exists in the SCCS file to which changes will be made to make the new delta.
- <new SID>
- Specifies the SID for the new delta to be created.
- Contains the login name of the user who will make the delta (that is, who executed a get for editing).
- Contains the date that get -e was executed, in the format used by the prs :D: data keyword.
- Contains the time that get -e was executed, in the format used by the prs :T: data keyword.
If there is more than one named file or if a directory or standard input is named, each pathname is written before each of the preceding lines:
Used only for optional informative messages concerning SCCS files with no impending deltas, and for diagnostic messages.
The following exit values are returned:
- Successful completion.
- An error occurred.
