I have to write a scripted for work. I never had to this before. The program has to do with nslookup. What scriptrd could I write just so I could type the IP and not type nslookup then the IP. Like I said just so I could type the IP.

Create a file with just one line in it:

nslookup -timeout=10 ${1:?Specify IP address}

Name the file "lookup" or whatever, but do not name it nslookup since that would conflict with the real command. Now enable the script for execution:

chmod 755 lookup

Then run it like this:

lookup 202.194.15.145

Note that the system could find another script in your PATH before it finds this one. To confirm which file it sees first in PATH, you can do:

which lookup

Sorry, that script will run in your default shell. It is valid for sh and ksh, but not for csh, and I see that the subject of your post is c-shell.

The first line of a script can specify which shell it is to run in. The following script will work for csh:

#!/bin/csh
if ( $1 == '' ) then
echo '\nUsage: lookup \n'
exit
endif
echo '**************************************'
nslookup -timeout=10 $1
echo '**************************************'

Make sure that /bin/csh is the proper location of your csh (you can do "which csh").
