cal writes a calendar on the standard output.
Syntax
cal[[ month] year] |
No argument specified: cal prints the calendar for the current month. month cal prints the calendar for the specified month. The possible values for month are 1 to 12. If you specify a value for month, you must also specify a value for year. month not specified: year The calendar for the specified year is printed. The possible values for year are 1 to 9999. Please note that cal 10, for example, refers to 10 A.D., not 2010. If you call cal using the argument 1752 or the arguments 9 1752, the output for September is shorter than usual. This is because cal allows for an adjustment of 11 days which took place in that month in 1752. |
Exit status
| The exit status is non-zero if the values specified for year or month lie outside the permissible range. |
Error
The values you have specified for year or month are not within the permissible range. |
Variable
TZ Determine the timezone used to calculate the value for the current month. |
Locale
The following environment variables affect the execution of cal: LANG Provide a default value for the internationalization variables that are unset or null. If LANG is unset of null, the corresponding value from the implementation-specific default locale will be used. If any of the internationalization 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 internationalization 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_CTYPE governs character classes, character conversion (shifting) and the behavior of character classes in regular expressions. LC_MESSAGES Determine the locale that should be used to affect the format and contents of diagnostic messages written to standard error. LC_TIME Determine the format and contents of the calendar. NLSPATH Determine the location of message catalogs for the processing of LC_MESSAGES. |
