NAME

calendar - reminder service (LEGACY)

SYNOPSIS

calendar 

DESCRIPTION

The calendar utility consults the file calendar in the current directory and writes lines that contain today's or tomorrow's date anywhere in the line to standard output. On Fridays and weekends, tomorrow extends to the following Monday, inclusive.

OPTIONS

None.

OPERANDS

None.

STDIN

Not used.

INPUT FILES

The calendar file in the current directory is a text file. Each line can contain text that includes a string, in any location, that is interpreted as today's or tomorrow's date. Month-day date formats such as Aug. 24, august 24 and 8/24 are recognised.

ENVIRONMENT VARIABLES

The following environment variables may affect the execution of calendar:

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 input files).

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 of the date strings recognised by the calendar utility.

NLSPATH

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

TZ

Determine the timezone used to qualify the date strings recognised by the calendar utility.

ASYNCHRONOUS EVENTS

Default.

STDOUT

The standard output contains all of the selected lines from the calendar file.

STDERR

Not used.

OUTPUT FILES

None.

EXTENDED DESCRIPTION

None.

EXIT STATUS

0

CONSEQUENCES OF ERRORS
