SGI Tips

• There's tons of documentation on-line. Select 'On-line documents' from the 'Help' menu in the Toolchest (upper-left corner). There is documentation for all sorts of stuff including OpenGL, CaseVision, etc.
• You can have as many Unix Shells as you like. Go to Desktop/Unix Shell to create a new one.
• Closing a shell does NOT log you out. To log out, you must select log out from the Desktop menu in the Toolchest. Also, if you hold down the left or the right mouse-button while over the desktop, you will get a pulldown menu with the Log Out option.
• Be sure to confirm your Log Out request. Don't just click log out, and leave!
• Windows and programs save their state when you log out. This is handy because you can have a "winterm" shell, a clock, etc. all come up everytime you login. This also means that you should quit all other programs before you logout.

Here are some handy aliases

# Check for runaway processes
# (of course, replace <username> with your login)
alias psf      'ps -ef | grep <username>'

# This is handy for keeping a window logged into your
# account on the instructional machines to check mail, read news, etc.
alias sanjuan 'xterm -T sanjuan -e rlogin sanjuan &'
alias orcas    'xterm -T orcas -e rlogin orcas &'

Some Handy Tools

% clock

(pretty self-explanatory)

% gdiff

this is a very impressive, graphical way of doing 'diff.'

% capture

Useful for recording still iamges using the IndyCam. Will also record movies, just audio, or can take screen shots.

% gr_osview

(displays CPU usage: handy for determining whether your program is calculating, or hung)

% ov

(desks overview. despite the 20" monitors, you'll find yourself running out of desktop space, especially when debugging. this allows multiple desktops)

% ipaste filename.rgb

All this program does is view *.rgb images. Although this is all it does, it does it really fast.

% imgview

(like xview, but does a better job with 24-bit color, this just does viewing though)

% imgworks

(like imgview, but has several nice editing features as well)

Some other fun things

• Graphics demos: select 'Graphics Demos' from the 'Find' menu in the toolchest.
• recon: See who is on the lab machines. Run: '/cse/courses/cse457/bin/recon'. Make sure you have each of the indys in your .rhosts file.
