       touch - change file timestamps

       touch [OPTION]... FILE...

       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

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

       --help display this help and exit

	      output version information and exit

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

       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  calendar  date,  time of day, time zone, day of week, relative
       time, relative 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.
