An XARGS question

[Michael Yep]

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
