The operation thus requires the following:
If you don't have eXceed, then there is a demo version of X-Win32 available, which you can install. It works pretty well for me! Alternatively, here is a weaker free server, but one which comes in Windows and Mac varieties!
who
command in your telnet session, looking for your
username (which I will denote by my_username):who who |more who | grep my_username(try all three). The first command will probably spew out more info than you need; the second will page the output, so that none of it streams off the page before you have time to read it; while the third actually saves you the trouble of scanning, and just lists the lines that contain your username (grep is one of the UNIX pattern scanners - you know that someone is a UNIX person when they use "grep" as a verb: "Yeah, I grepped your meaning, there, buckeroo...").
echo $SHELL
if you see the name "csh" or "tcsh" in the output of that command (most of you), then you will type
setenv DISPLAY machine.name:0.0
If you see the name "ksh", type
DISPLAY=machine.name:0.0; export DISPLAY
where machine.name is the machine name from the last who/grep line above. This should look like xerxes.sph.umich.edu, or perhaps like this: 198.108.20.8. At any rate, tack the :0.0 onto it and you've got a DISPLAY.
fs lq
once you get onto your machine, and check how many of your megs you have left. If you're at 90% or more of % Used, you're in space trouble and you'll have to be careful.
Other places have other means of checking your quota. Check with your system administrator if you're worried.
xv
), which is
extremely useful for image conversion. If you don't already have the file snow.gif, then you should download it to your computer
and into your Unix account (right click on the link to save it to your
computer). Type the following in your telnet session:
xv snow.gif
(Right click on the image to bring up a menu of operations.) Try using the Save button: save this image as a jpeg to your home directory.
xv might prove useful in a variety of ways in this course, and is a handy piece of software in general. For example
