Usage: touch [OPTION]... FILE...
Update the access and modification times of each FILE to the current time.

  -a                     change only the access time
  -c                     do not create any files
  -d, --date=STRING      parse STRING and use it instead of current time
  -f                     (ignored)
  -m                     change only the modification time
  -r, --reference=FILE   use this file's times instead of current time  
  -t STAMP               use MMDDhhmm[[CC]YY][.ss] instead of current time
      --time=WORD        access -a, atime -a, mtime -m, modify -m, use -a
      --help             display this help and exit
      --version          output version information and exit
