Create user add lines from partial passwd file

Handy if you are installing a new server or recovering an old one and you have a passwd file with the accounts you want to add to the server. If you edit the file so that only the accounts that you want to add are left this line will spit out the correct useradd lines. The uid, gecos and shell will be preserved. Show Sample Output

download and run script from trusted webserver

This is a simple command that you can run complex shell scripts via ssh. For instance if you would have to run the same process on several hundred hosts. There is no security so you have to trust the server that is sourcing this script.

Debug a remote php application (behind firewall) using ssh tunnel for XDEBUG port 9000

If you need to xdebug a remote php application, which is behind a firewall, and you have an ssh daemon running on that machine. you can redirect port 9000 on that machine over to your local machine from which you run your xdebug client (I am using phpStorm) So, run this command on your local machine and start your local xdebug client, to start debugging. more info: http://code.google.com/p/spectator/wiki/Installing

resume other user's screen session via su, without pty error

Normally, if you su to another user from root and try to resume that other user's screen session, you will get an error like "Cannot open your terminal '/dev/pts/0' - please check." This is because the other user doesn't have permission for root's pty. You can get around this by running a "script" session as the new user, before trying to resume the screen session. Note you will have to execute each of the three commands separately, not all on the same line as shown here.
