       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 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.
