Hi Again!

Here is an extended part of the script... I'd like to be sure that sed will work instead of grep....
grep -l "search string in files I want" smtp*.tmp > email_filenames_list.txt ;
cat email_filenames_list.txt | xargs cat >> smtp_all_emails_logs.txt ;
sed '/[A-Z][0-9]/ s#.*>\([A-Z][0-9]\).*#,1,,,1,\1#' smtp_all_emails_logs.log > out.txt ;
grep "^To" smtp_all_emails_logs.txt | awk '{print ","$2}' > recipients.txt ;
paste out.txt recipients.txt

the grep line definately works, but would sed run through a massive list of emails that have all been put in one file (smtp_all_email_logs.txt) and print:
etc in AIX environment

Another quick question: how can I stop a carrage return/line feed being included after the recipients email address? Cause it's screwing up my spreadsheet.
