Lab FAQ
1. I cannot access javac, java,
or pico.
Your login script may
have some problem, and it fails to set your path.
Just notice me during the lab. Let's try to recover
your login script.
In the meantime, you can start pico using the command
/usr/local/bin/pico. You can access the Java
compiler and the Java interpreter with /usr/local/java/bin/javac
and /usr/local/java/bin/java.
2. How to check my disk quota?
Currently, your default AFS disk quota should be 5MB. If you
use up your AFS disk quota, you can not login into
Lab computer or save any java file.
The AFS command "fs lq" will tell you your disk
quota (in 1-Kbyte blocks), how many of those blocks
are currently used, the percentage used, and the
percentage of space used on the disk partition that
you share with other users. Note that this command
will tell you this information about the AFS volume
that your current working directory resides in. If
your username does not appear in the volume name
listed with this command just "cd" to your home
directory.
The UNIX command "du" will give you a block count and an
idea of how much space is being used by a individual
directories and files. See the man page for this
command for the particular workstation you are on
3.How do I clean up my account to get more
space (core files specifically)?
Core files are dumps of memory that are kept in a
file for debugging purposes when a program crashes.
Typically you do not want these on your directories,
since they are rather large files. You can
periodically run a command that finds and removes
the core files:
find ~ -name core
