OK, you need to have the user enter a filename, and then a one or two word search string. The file is then searched and all lines matching the search string ('John' or 'John Smith') are extracted and written to a new file tempfile.YYYYMMDD; right?

If that's accurate, then I think this is all you need:

Code:
#!/usr/bin/env ksh
printf "enter filename: "
read filename
printf "enter search data (e.g. john or john smith) "
read search_string
grep "$search_string" $filename >testfile.$(date +%Y%m%d$H%M%S)

chgrp - Changes file group

SYNOPSIS
bool chgrp (string $filename, mixed $group) DESCRIPTION
Attempts to change the group of the file $filename to $group. Only the superuser may change the group of a file arbitrarily; other users may change the group of a file to any group of which that user is a member. PARAMETERS
o $filename - Path to the file. o $group - A group name or number. RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
Example #1 Changing a file's group <?php $filename = 'shared_file.txt'; $format = "%s's Group ID @ %s: %d "; printf($format, $filename, date('r'), filegroup($filename)); chgrp($filename, 8); clearstatcache(); // do not cache filegroup() results printf($format, $filename, date('r'), filegroup($filename)); ?> 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. SEE ALSO
chown(3), chmod(3). PHP Documentation Group CHGRP(3)
