Functions

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

What others think

You might want to filter out .ssh/config too:

for id in `ls -1 ~/.ssh | grep -v "authorized\|known_hosts\|config\|\."` ; do echo -n "$id: " ; ssh-keygen -l -f .ssh/$id ; done

Excellent point - thanks, added it.

It's still missing rc and environment. You can make it faster by not using grep:

for id in `ls -d ~/.ssh/!(authorized_keys|config|environment|known_hosts|rc|*.pub|*.bak)` ; do echo -n "$id: " ; ssh-keygen -l -f $id ; done

Oh, wait. You don't even need to use ls or a subshell:

for id in ~/.ssh/!(authorized_keys|config|environment|known_hosts|rc|*.pub|*.bak) ; do echo -n "$id: " ; ssh-keygen -l -f "$id" ; done
