NAME
touch - update date last modified of a file

SYNOPSIS
touch [ -c ] [ -f ] file ...

DESCRIPTION
Touch attempts to set the modified date of each file. If a file
exists, this is done by reading a character from the file and
writing it back. If a file does not exist, an attempt will be made
to create it unless the -c option is specified. The -f option will
attempt to force the touch in spite of read and write permissions
on a file.
