NAME
       touch - change file timestamps

SYNOPSIS
       touch [OPTION]... FILE...

DESCRIPTION
       Update  the  access  and modification times of each FILE to the current
       time.

       A FILE argument that does not exist is created empty, unless -c	or  -h
       is supplied.

       A  FILE	argument  string of - is handled specially and causes touch to
       change the times of the file associated with standard output.

       Mandatory arguments to long options are	mandatory  for	short  options
       too.

       -a     change only the access time

       -c, --no-create
	      do not create any files

       -d, --date=STRING
	      parse STRING and use it instead of current time

       -f     (ignored)

       -h, --no-dereference
	      affect each symbolic link instead of any referenced file (useful
	      only on systems that can change the timestamps of a symlink)

       -m     change only the modification time

       -r, --reference=FILE
	      use this file's times instead of current time

       -t STAMP
	      use [[CC]YY]MMDDhhmm[.ss] instead of current time

       --time=WORD
	      change the specified time: WORD is access, atime, or use: equiv-
	      alent to -a WORD is modify or mtime: equivalent to -m

       --help display this help and exit

       --version
	      output version information and exit

       Note that the -d and -t options accept different time-date formats.

DATE STRING
       The  --date=STRING  is  a mostly free format human readable date string
       such as "Sun, 29 Feb 2004 16:21:42 -0800" or "2004-02-29	 16:21:42"  or
       even  "next Thursday".  A date string may contain items indicating cal-
       endar date, time of day, time zone, day of week, relative  time,	 rela-
       tive date, and numbers.	An empty string indicates the beginning of the
       day.  The date string format is more complex than is easily  documented
       here but is fully described in the info documentation.
