NAME
       touch - change file timestamps

SYNOPSIS
       touch  [-acfm] [-r reference-file] [-t MMDDhhmm[[CC]YY][.ss]] [-d time]
       [--time={atime,access,use,mtime,modify}]	 [--date=time]	[--file=refer‐
       ence-file] [--no-create] [--help] [--version] file...

DESCRIPTION
       This manual page documents the GNU version of touch.  touch changes the
       access and modification times of each given file to the	current	 time.
       Files  that  do	not  exist  are created empty.	If the first file name
       given would be a valid argument to the -t option and  no	 timestamp  is
       given  with any of the -d, -r, or -t options and the -- argument is not
       given, that argument is interpreted as the time	for  the  other	 files
       instead of as a filename.

       If changing both the access and modification times to the current time,
       touch can change the timestamps for files that the user running it does
       not own but has write permission for.  Otherwise, the user must own the
       files.

   OPTIONS
       -a, --time=atime, --time=access, --time=use
	      Change the access time only.

       -c, --no-create
	      Do not create files that do not exist.

       -d, --date time
	      Use time (which can be in various common formats) instead of the
	      current  time.   It can contain month names, timezones, `am' and
	      `pm', etc.

       -f     Ignored; for compatibility with BSD versions of touch.

       -m, --time=mtime, --time=modify
	      Change the modification time only.

       -r, --file reference-file
	      Use the times of reference-file instead of the current time.

       -t MMDDhhmm[[CC]YY][.ss]
	      Use the argument (months, days, hours, minutes, optional century
	      and years, optional seconds) instead of the current time.

       --help Print a usage message on standard output and exit successfully.

       --version
	      Print  version information on standard output then exit success‐
	      fully.
