Hello
Is there a way to have xargs or perhaps another tool take a list from
stdin and put it somewhere besides the last argument?
Say if i want to get all the offending IPs (bad logins) for a given day
then i want to take that list and see if its in a file called blacklist
lastb -ai |fgrep "Jul 18" |awk '{print $10 }'|sort|uniq | xargs grep ???
blacklist
where ??? would be where the stdin goes
lastb -ai |fgrep "Jul 18" |awk '{print $10 }'|sort|uniq | xargs
--max-args=1 -i\?\?\? grep \?\?\? blacklist
