GNU shell utilities
10.1 date: Print or set system date and time
date with no arguments prints the current time and date, in the
format of the `%c' directive (described below). Synopses:
| | date [option]... [+format]
date [-u|--utc|--universal]
[ MMDDhhmm[[CC]YY][.ss] ]
|
If given an argument that starts with a `+', date prints the
current time and date (or the time and date specified by the
--date option, see below) in the format defined by that argument,
which is the same as in the strftime function. Except for
directives, which start with `%', characters in the format string
are printed unchanged. The directives are described below.
