cal - print a calendar

 SYNOPSIS

cal [[month] year ]

 DESCRIPTION

The cal utility writes a Gregorian calendar to standard output. If the year operand is specified, a calendar for that year is written. If no operands are specified, a calendar for the current month is written.

 OPTIONS

None.

 OPERANDS

The following operands are supported:

month

Specify the month to be displayed, represented as a decimal integer from 1 (January) to 12 (December). The default is the current month.

year

Specify the year for which the calendar is displayed, represented as a decimal integer from 1 to 9999. The default is the current year.

 ENVIRONMENT VARIABLES

The following environment variables affect the execution of cal:

LANG

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.

LC_ALL

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

LC_CTYPE

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).

LC_MESSAGES

Determine the locale that should be used to affect the format and contents of diagnostic messages written to standard error, and informative messages written to standard output.

LC_TIME

Determine the format and contents of the calendar.

NLSPATH

Determine the location of message catalogues for the processing of LC_MESSAGES .

TZ
