.SH SYNOPSIS
.B touch
[\fIOPTION\fR]... \fIFILE\fR...
.SH DESCRIPTION
.\" Add any additional description here
.PP
Update the access and modification times of each FILE to the current time.
.PP
A FILE argument that does not exist is created empty, unless \fB\-c\fR or \fB\-h\fR
is supplied.
.PP
A FILE argument string of \- is handled specially and causes touch to
change the times of the file associated with standard output.
.PP
Mandatory arguments to long options are mandatory for short options too.
.TP
\fB\-a\fR
change only the access time
.TP
\fB\-c\fR, \fB\-\-no\-create\fR
do not create any files
.TP
\fB\-d\fR, \fB\-\-date\fR=\fISTRING\fR
parse STRING and use it instead of current time
.TP
\fB\-f\fR
(ignored)
.TP
\fB\-h\fR, \fB\-\-no\-dereference\fR
affect each symbolic link instead of any referenced
file (useful only on systems that can change the
timestamps of a symlink)
.TP
\fB\-m\fR
change only the modification time
.TP
\fB\-r\fR, \fB\-\-reference\fR=\fIFILE\fR
use this file's times instead of current time
.TP
\fB\-t\fR STAMP
use [[CC]YY]MMDDhhmm[.ss] instead of current time
.TP
\fB\-\-time\fR=\fIWORD\fR
change the specified time:
WORD is access, atime, or use: equivalent to \fB\-a\fR
WORD is modify or mtime: equivalent to \fB\-m\fR
.TP
\fB\-\-help\fR
display this help and exit
.TP
\fB\-\-version\fR
output version information and exit
.PP
Note that the \fB\-d\fR and \fB\-t\fR options accept different time\-date formats.
.SH "DATE STRING"
.\" NOTE: keep this paragraph in sync with the one in date.x
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
calendar date, time of day, time zone, day of week, relative time,
relative 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.
