how to test csh?
 

I am new to csh and i would like to learn csh (since most of the script is written in csh)

test.sh
#!/bin/csh -f
set mymachine = `uname -n`

is there a way to try and test it?

echo $mymachine
mymachine: Undefined variable.

Using the sha-bang as you did in your script should be enough. Otherwise you can create a test user and assign /bin/tcsh as the default shell, so that you have a complete login environment to test with. Regarding the Undefined variable error, it's really strange. Is the echo command inside the script?

Finally, a good reference for csh is www.kitebird.com/csh-tcsh-book/csh-intro.pdf. Hope this helps.

i got it already
I use printf command to display at the xterm
