Hi all,
I have a problem at the moment that has stumped me for a couple of days now...

I have a file containing public key for ssh, called authorized_keys2, containing :

ssh-dss xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxbbbbbbbbbbbbbxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxx== root@servername

I want to create a perl one liner so that it will match only the 'root@servername' part of the file and returns it to me. Is this possible? Appreciate your help. I've tried to do it with awk and sed with no success.....

assuming the data you provided goes line by line, the root@servername portion is the last field

perl -nae '@foo = split; print $foo[2];' the_file
