       touch - change file timestamps


       touch [OPTION]... FILE...


       Update the access and modification times of each FILE to the current

       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

       -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 [[CC]YY]MMDDhhmm[.ss]
              use specified time instead of current time, with a date-time
              format that differs from -d's

              specify which time to change: access time (-a): 'access',
              'atime', 'use'; modification time (-m): 'modify', 'mtime'

       --help display this help and exit

              output version information and exit


       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.
