Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

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

check out the -N option to ssh

Do not execute a remote command. This is useful for just forwarding ports (protocol version 2 only).

You might want to use ~/stop or ~/.stop as the file to stop your loop, since it's usually possible for anyone on the system to reach /tmp (doesn't matter on a single-user box, but it's generally a good idea to stay in your home directory anyway).

Or just run the who shebang out of /etc/inittab with the "respawn" option. See http://www.deer-run.com/~hal/sysadmin/SSH-SyslogNG.html

Dunno about this "target" piece in your command.

I assume your command is meant to provide a way to keep trying to connect if it fail. Inspired of this, I wrote my own command that help me automatically reconnect immediately after the connecting pipe is broken:

while true; do if ! nc -z localhost 7070 > /dev/null; then ssh -N -D -p 22 [email protected]; else echo 'not connected, retry after 10 seconds...'; fi; sleep 10; done
