As I got hit with a meme about command line stuff, I figured I'd share an update to my favorite bash completion:
SSH_COMPLETE=( $(cut -f1 -d' ' ~/.ssh/known_hosts |\
tr ',' '\n' |\
sort -u |\
grep -e '[:alpha:]') )
complete -o default -W "${SSH_COMPLETE[*]}" ssh
If you ssh directly to IP addresses very often, you might want to leave
off the last grep -e.
Not going to tag anyone, but if you have a favorite completion, please share! (I suggest not in a comment on this post as my comment system does not preserve any formatting).
