NAME
shtool-mdate - GNU shtool pretty-print last modification time SYNOPSIS
shtool mdate [-n|--newline] [-z|--zero] [-s|--shorten] [-d|--digits] [-f|--field-sep str] [-o|--order spec] path DESCRIPTION
This command pretty-prints the last modification time of a given file or directory path, while still allowing one to specify the format of the date to display. OPTIONS
The following command line options are available. -n, --newline By default, output is written to stdout followed by a "newline" (ASCII character 0x0a). If option -n is used, this newline character is omitted. -z, --zero Pads numeric day and numeric month with a leading zero. Default is to have variable width. -s, --shorten Shortens the name of the month to a english three character abbreviation. Default is full english name. This option is silently ignored when combined with -d. -d, --digits Use digits for month. Default is to use a english name. -f, --field-sep str Field separator string between the day month year tripple. Default is a single space character. -o, --order spec Specifies order of the day month year elements within the tripple. Each element represented as a single character out of ``"d"'', ``"m"'' and ``"y"''. The default for spec is ``"dmy"''. EXAMPLE
# shell script shtool mdate -n / shtool mdate -f '/' -z -d -o ymd foo.txt shtool mdate -f '-' -s foo.txt HISTORY
The GNU shtool mdate command was originally written by Ulrich Drepper in 1995 and revised by Ralf S. Engelschall <rse@engelschall.com> in 1998 for inclusion into GNU shtool. SEE ALSO
shtool(1), date(1), ls(1). 18-Jul-2008 shtool 2.0.8 SHTOOL-MDATE.TMP(1)
