Ask SIPB - August 29, 2007

Want to use the software on Athena? Wondered what sorts of cool things you can do? In this column, we discuss lockers on Athena, and the things you can find in them.

What are lockers?

Lockers organize files and software on Athena, and allow them to be accessed more easily. They eliminate the need to use long pathnames like /afs/, and allow you to quickly run programs without needing to know exactly where they are located.

How do I use a locker?

The most common way to use a locker is to use the add command. This will attach the locker — make it available through /mit/lockername — and add the locker to your path. For example, to run the mplayer program in the outland locker, type:

athena% add outland
athena% mplayer

You can put a line in a text file called .environment file in your home directory to add lockers automatically when you log in. Programs such as pico (terminal-based) and gedit (GUI) allow you to edit text files. For example, you may add a line such as:

add 6.001 sipb outland matlab

The second way to use a locker is the attach command. This will make a locker accessible at /mit/lockername the same way add does, but will not add the locker to your path.

What are some common useful lockers?

sipbsoftware supported by SIPB
outlandsoftware less actively supported and maintained by SIPB
consultAthena-related utilities maintained by OLC
gnucommon Unix utilities maintained by the Free Software Foundation
abiworda fast-loading word processor
gnumerica fast-loading spreadsheet, an office suite
gamesgames and other fun utilities
imIM programs, such as gaim
weatherthe weather program
math, matlab, mapleMathematica, Matlab, and Maple software, respectively

Is there an easy way to find out where something is located?

The whichlocker program, located in the outland locker, tells you where many programs are located, and what platforms they are available for.
athena% whichlocker mmblanche
Locker software on Athena is maintained by many different people.
Don't run this unless you know the maintainer can be trusted.
"mmblanche" is in "consult" for linux, NT, and sun4

What cool stuff can I find in some of these lockers?

For more information about most of these programs, you can type man programname after adding the appropriate locker.
