UNIX for Dummies Questions & Answers

I am new to unix and therefore I did a lot of reading before posting. So please, if this has been answered before, forgive me for re-posting and point me to the right place for the answer. I have spent many hours searching the net and read over 50 posts in this forum and even tried a few thing but still no success.

Here is my simple script file named al:

#!/bin/csh
echo Setting alias....
alias ss "vi myfile.log"

I type al on the command line, it displays the message on the screen as per Echo command but doesn't seem to set the alias ss. When I type ss on the command line, I get:

ss: command not found.

I even tried ./al and then ss as read in some posts but didn't work. Also tried with '=' sign i.e. ss="vi myfile.log", still no go. If I type the command interactively then the alias works fine.

I am using c shell i.e. when I type echo $shell, I get /bin/csh.

Any help to get this working will be greatly appreciated and save me a lot of time.

Thanks.

Invoke as dot-space-scriptname if you want anything set in the script to stay in the current environment.

Code:

. ./scriptname

Tried that. I get the message "Permission Denied".

. ./al [Enter]
/idn/app/bin/.: Permission Denied.

I don't know what that means.

let try this

Code:

chmod u+x al

So must give execute permission to your script

Tried that. Still no go. Same message.

Permissions typically cascade along the path, so be sure that your UID has access to execute along the entire path to your script.

Otherwise, if your script is exclusively to set the named alias...just add this to your . file and have it set on login.

csh...bad!

Code:

ls -ld .

I don't have problem executing other scripts. Only the alias command is not working.

Setting it on login kinda defeats the purpose. This is a script that I want to run on the fly passing a parameter to the script and might run it several times during a session with different parameters. For example, I would like to eventually modify the alias command to some thing like this:

alias ss "vi $1.log"
alias tt "vi $1.txt"
alias kk "vi $1.ksh"

and run the script just by typing al myfile to set the 3 aliases as above pointing to myfile.
