What Others Think

We're on a bit of a roll for "tidyable" commands... First, you can combine grep and awk: awk '/page.php/{print $1} /var/log/httpd/access_log | ... Then sort and uniq: ... | sort -u | ... The perl's OK, but I would have probably dropped it and changed the awk: awk '/page.php/{printf("ipset add banned -! -q %s\n",$1);} /var/log/httpd/access_log | sort -u | sh Run awk on the file '/var/log/httpd/access_log' Search for 'page.php' and for any matches output an ipset command for $1 Sort and unique the results Then execute the commands with sh
