Frequently used Unix commands

• Kill all remote processes for a workstation that's locked up
1. Login to the locked up station remotely
2. type

3. This should immediately put the locked up workstation back to the login prompt
• Run program on server overnight, while you're logged out
1. Login to remote server, using

   ssh <server name>

   (note: ssh -Y allows X11 forwarding of applications, like "remote desktop")
2. type

   screen

3. type

   nice -10 <name of program> [program parameters]

   e.g. nice -10 em -v foo.son
4. Get process running, then to escape from screen while leaving it running, press <Ctrl> a d
5. Now you should be able to entirely logout and come back later
6. To get back into your program later, login to server using

   ssh <server name>

   then type

   screen -r

   You will then resume your previous session, or if you had multiple sessions open, you will have a list of them returned to you. To resume the desired sessions, type:

   screen -r <5 digit session ID>

   then type

   sonnet

   to execute
• Running applications remotely (X11 Forwarding)
1. This is not usually necessary, but it is possible.
