TOUCH(1)                         User CommandsTOUCH(1)NAME       touch - change file timestampsSYNOPSIS       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.AUTHOR       Written  by  Paul  Rubin, Arnold Robbins, Jim Kingdon, David MacKenzie,       and Randy Smith.REPORTING BUGS       GNU coreutils online help: <https://www.gnu.org/software/coreutils/>       Report touch translation bugs to <https://translationproject.org/team/>COPYRIGHT       Copyright (C) 2018 Free Software Foundation, Inc.
