TOUCH(1) (Directory and File Management Utilities) TOUCH(1)
NAME
touch - update access and modification times of a file
SYNOPSIS
touch [ -amc ] [ mmddhhmm[yy] ] files
DESCRIPTION
touch causes the access and modification times of each
argument to be updated. The file name is created if it does
not exist. If no time is specified (see date(1)) the
current time is used. The -a and -m options cause touch to
update only the access or modification times respectively
(default is -am). The -c option silently prevents touch
from creating the file if it did not previously exist.
The return code from touch is the number of files for which
the times could not be successfully modified (including
files that did not exist and were not created).
