OPTIONS
[Tru64 UNIX] Calls calendar for all users who have a calendar file in their home directories and sends reminders by mail.
This flag is usually used only by the superuser as part of daily administrative procedures.
DESCRIPTION
The calendar command reads a file named calendar in your current (usually home) directory and writes to standard output any line in the
file that contains the current date or the next day's date.
The calendar command recognizes date formats such as Dec. 7 or 12/7. It also recognizes the special character * (asterisk) to match any
month. For example, it interprets */7 or * 7 as the seventh day of every month.
On Fridays, calendar writes all lines containing the dates for Friday, Saturday, Sunday, and Monday. It does not recognize holidays, so if
the next day is a holiday calendar prints lines for that day, rather than for the next working day.
For you to get reminder service when other users run calendar -, your calendar file must be readable by others (see the chmod command).
NOTES
The calendar utility is marked LEGACY in XCU Issue 5.
EXIT STATUS
The following exit values are returned: Successful completion. An error occurred.

ENVIRONMENT VARIABLES
The following environment variables affect the execution of calendar: [Tru64 UNIX] If this variable is set, the calendar command uses its
value as the full pathname of a template file that contains format strings. The strings consist of field descriptors and text characters
which are used to provide a more robust set of allowable date formats in different languages using the appropriate settings of the environ-
ment variables LANG or LC_TIME. See environ(5) for more information. The list of allowable field descriptions is provided in the date(1)
reference page. Provides a default value for the internationalization variables that are unset or null. If LANG is unset or null, the cor-
responding value from the default locale is used. If any of the internationalization variables contain an invalid setting, the utility
behaves as if none of the variables had been defined. If set to a non-empty string value, overrides the values of all the other interna-
tionalization variables. Determines the locale for the interpretation of sequences of bytes of text data as characters (for example, sin-
gle-byte as opposed to multibyte characters in input files). Determines the locale for the format and contents of diagnostic messages
written to standard error. Determines the format of date strings recognized by the calendar command. Determines the location of message
catalogues for the processing of LC_MESSAGES.
