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.
