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.
