This might work for you. I don't really have all the info from you that I would need, but assuming that there is a file "url.txt" that is formated like this:
http://www.feathertrip.net/cgi-bin/index.cgi?client=23894749&; http://www.feathertrip.net/cgi-bin/index.cgi?client=23894749&; http://www.feathertrip.net/cgi-bin/index.cgi?client=23894749&; http://www.feathertrip.net/cgi-bin/index.cgi?client=23894749&; http://www.feathertrip.net/cgi-bin/index.cgi?client=23894749&; Yada yada yada.... The below code should work for you: #!/usr/bin/perl -w $file = "./url.txt"; open FILE, "$file" or die "Cannot open file $file: $!\n"; while(<FILE>) { s/^(.*)\?(client\=\d{8}\&)$/$1/; print "$1\n"; } close(FILE); Lemme know if you have anyother questions.

But before it saves it I want it to strip out the client id from the urls. They are always in the same format: client=xxxxxxxx& # 8 digits and then ampersand so what I want to strip out is stuff like: client=23894749& i am a newbie so regex is a little out of my league. any help appreciated! thanks, Rory -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
