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: equiv-
              alent 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  cal-
       endar  date,  time of day, time zone, day of week, relative time, rela-
       tive 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.
