<p><i>touch</i> sets the access and modification timestamps of files.
By default,
both the access and modification times are set to the current time.
If necessary,
files will be created.</p>

<p><i>touch</i> exits succesfully if and only if all timestamps could be set succesfully.</p>

<h2><a class='u' href='#___top' title='click to go to top of document'
name="OPTIONS"
>OPTIONS</a></h2>

<p><i>head</i> accepts the following options:</p>

<dl>
<dt><a name="-a"
>-a</a></dt><p class="pad"></p>

<dd>Set the access time of the specified files only,
unless <i>-m</i> is given as well.</dd><p class="pad"></p>

<dt><a name="-c"
>-c</a></dt><p class="pad"></p>

<dd>Do not create non-existing files.
No warning is generated,
and it will not influence the exit status.</dd><p class="pad"></p>

<dt><a name="-f"
>-f</a></dt><p class="pad"></p>

<dd>This option is ignored,
and only recognized for compatability reasons.</dd><p class="pad"></p>

<dt><a name="-m"
>-m</a></dt><p class="pad"></p>

<dd>Set the modification time of the specified files only,
unless <i>-a</i> is given as well.</dd><p class="pad"></p>

<dt><a name="-r_file"
>-r file</a></dt><p class="pad"></p>

<dd>Use the access and modification time of <i>file</i> instead of the current time.</dd><p class="pad"></p>

<dt><a name="-t_[[CC]YY]MMDDhhmm[.SS]"
>-t [[CC]YY]MMDDhhmm[.SS]</a></dt><p class="pad"></p>

<dd>Set the access and modification times to the specified time.
If <b>YY</b> is present,
but <b>CC</b> is not,
then <b>CC</b> is assumed to be 19 if <b>YY</b> is larger than 69,
and 20 otherwise.
If <b>YY</b> is not present,
the current year is assumed.</dd><p class="pad"></p>

<dd>It should be noted that many systems cannot deal with timestamps before Jan 1,
1970 or after Jan 19,
2038.</dd><p class="pad"></p>

<h1><a class='u' href='#___top' title='click to go to top of document'

>ENVIRONMENT</a></h1>

<p>The working of <i>touch</i> is not influenced by any environment variables.</p>

<h1><a class='u' href='#___top' title='click to go to top of document'
name="BUGS"
>BUGS</a></h1>

<p><i>touch</i> does not implement the <i>-f</i> option.</p>

<p><i>touch</i> uses <code lang='und' xml:lang='und'>Time::Local</code> to translate the time format to epoch seconds</p>

>STANDARDS</a></h1>

<p>This <i>head</i> implementation is compatible with the <b>OpenBSD</b> implementation,
except for the <i>-f</i> option.</p>
