Variable Declaration in shell scripts...

vinaytp · 02-04-2010, 09:35 AM

Hi all..

We have a file that declares many environmental variables. Out of which I have doubt on few. These variables are declared in UNIX environment. We are planing to migrate them along with applications to Linux.

Code:

export MAILSERVER="%new@hub"
MAIL_USERS="vinay.new"{MAILSERVER}",vijay.new"{MAILSERVER}

Does the above declarations work in Linux ?

The above declarations expands to

Code:

mail vinay.new%new@hub,vijay.new%new@hub

which looks little wierd.

I normally use vinay.linux.com being the mail server

Code:

mail vinay.new@vinay.linux.com,vijay.new@vinay.linux.com

This perfectly works fine

Thanks in advance...

Well, have you TRIED IT?? Also, what language are you writing this in?? Just bash/shell script, or something else?

It just uses k shell in Unix. SO we are porting all our applications to K shell in Linux..These are just k shell scripts.

Still Analisation phase is going, Not did not got a chance to try. will this work in Linux ?

Can you please suggest...
Thanks...

Yes...I suggest you try it.

ksh should function the same, but the only way to know is to actually do it.

When you try it you can see what the shell is doing by turning tracing on with set -xv (turn off with set +xv)
