touch -- Sets access and modification time of file


int touch ( string filename [, int time])

Attempts to set the access and modification time of the file named by filename to the value given by time. If the option time is not given, uses the present time. This is equivalent to what utime (sometimes referred to as utimes) does.

If the file does not exist, it is created.

Returns TRUE on success, FALSE on failure.

Example 1. touch() example

if (touch ($FileName)) {
    print "$FileName modification time has been 
           changed to todays date and time";
} else {
    print "Sorry Could Not change modification time of $FileName";
