|I keep seeing "Over Quota" messages. What does that mean and what do I do about it.||
It means you've used all your allocated disk space. To save
more files, you'll need to remove some.
Things to check:
|I'm trying to reduce my quota usage but I can't get it to go down even though I've thrown a lot of files in the trash.||Just like PC's, the files don't disappear when you throw them in the trash. You have to empty the trash to get them removed from your quota usage. If you've logged in using SSH, rm the file.|

My session just has a >
When I try to run a command like 'ls', it says command not found

file and made mistake or deleted your .cshrc file.
See dos2unix above to fix
/bin/cp .cshrc .cshrc.broken
/bin/cp /dcs/skel/.cshrc . (that's a dot)
Always make a backup of the file before you edit it.
I keep getting the message:
You already have a magic process running
|You may one run one magic process because it takes up too much system resources. If you've forgotten to exit the process, you can identify it using the 'ps' command and kill it using the 'kill' command (see Useful Commands above).|
I have a desktop that looks funny and I can't log out
You probably don't have the CDE desktop. If you have a
xterm window, run the command 'kill -9 -1' to kill your
When you log in again, after you type your login name and press enter but before you type your password, select Options -> Session -> Common Desktop Environment (CDE).
