calendar — Display all current appointments
Format
Description
calendar [–]
Note: The calendar utility is fully supported for compatibility with older UNIX
systems. However, because it is no longer supported by POSIX.2 IEEE
standard 1003.2-1992, this utility should be avoided for applications intended
to be portable to other UNIX-branded systems.
If you do not specify any options, calendar displays all current appointments on
standard output (stdout). It searches the file calendar in the current directory,
looking for lines that match either today’s date or tomorrow’s date. On Friday,
Saturday, or Sunday, tomorrow extends through to Monday. Each appointment must
fit on a single line, with the date formatted as one of:
January 27
1/27
jan 27
Note: The name of the month can be abbreviated to three letters. Also, the case is
not significant and the month can be given numerically.
