I have a current code working(named subst1) having a user be able to type this line to substitute words using the sed command:
Here is my shell script:
The problem with this script is that it changes the date and creates a bak file. I need to alter this script so that when a user inputs the command line, the script checks if the given old-pattern is in the file and if it is, go ahead and do the substitution. If the old-pattern is not found, the script should do nothing. Any help would be appreciated!

LEARN ABOUT PHP
chown
CHOWN(3) 1 CHOWN(3)chown - Changes file ownerSYNOPSIS
bool chown (string $filename, mixed $user)
DESCRIPTION
Attempts to change the owner of the file $filename to user $user. Only the superuser may change the owner of a file.
PARAMETERS
o $filename
- Path to the file.
o $user
- A user name or number.
RETURN VALUES
Returns TRUE on success or FALSE on failure.
EXAMPLES
Example #1
Simple chown(3) usage
<?php
// File name and username to use
$file_name= "foo.php";
$path = "/home/sites/php.net/public_html/sandbox/" . $file_name ;
$user_name = "root";
// Set the user
chown($path, $user_name);
// Check the result
$stat = stat($path);
print_r(posix_getpwuid($stat['uid']));
?>
The above example will output something similar to:
Array
(
[name] => root
[passwd] => x
[uid] => 0
[gid] => 0
[gecos] => root
[dir] => /root
[shell] => /bin/bash
)
NOTES
Note
This function will not work on remote files as the file to be examined must be accessible via the server's filesystem.
Note
When safe mode is enabled, PHP checks whether the files or directories being operated upon have the same UID (owner) as the script
that is being executed.
