Disk Quotas

• Student: 50M bytes.
• TA: 50M bytes.
• Faculty: 25M bytes.
• Course: 50M bytes.

When a filesystem write you attempt would exceed your quota, the write will fail and the system returns the EDQUOT error. Most programs check for this and print out a "Disc quota exceeded" message. It is possible that some programs might not check for this error. If any system program you use, such as an editor or mail program, fails to inform you when you exceed your quota, and just silently truncates your files, please mail to root and report the details.

To find out your disk quota and usage, you can use the command "quota -v". Another thing you can always do is to use the du command while in your home directory to find out the total amount of disk space you are using. You should run this every so often to keep tabs on the situation.

You should be aware that if you use Netscape in the default configuration, it will use up to 5M bytes as a cache of recently visited pages and images. The cache is stored in the subdirectory .netscape-cache of your home directory. You can delete anything in there without ill effects. You can also reduce Netscape's appetite for disk space by selecting the Preferences item in the Options menu, and then selecting the ``Network and Cache'' screen. Set the cache size down from 5000K bytes to something like 2000K or 1000K bytes. Then select the ``Save Options'' item from the Options menu to save your changes permanently.
