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: equiv-
              alent 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 cal-
