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: equivalent 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  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.
