UNIX for Dummies Questions & Answers

In my script when I change an env variable in the parent shell it is only changed for that session - it there away to change it permanently using a script so that when I use rlogin (create a child session) that the env variable is set correctly?

Basically what I am trying to do is to pass a variable using using rlogin that contains a string. If I can us rlogin is there an alternative ?

Thanks

If it doesn't need to change frequently you can just set it in your login scripts (i.e. .profile or similar, depending on your choice of shell) on the remote host.

The env will be changed frequently so I cant set it in the .profile - I need for my script to change it.

Thanks anyway

Are you exporting the variable. You can source a script:

Code:

#!/bin/ksh
export MYVAR='a string of characters'

Source the script above

Code:

.  script.sh

That's a leading dot - space before the script name

When you say "rlogin (create a child session)"... you are actually doing that on a remote host, right?

Also, is ssh an available alternative to rlogin at your site?

Thanks - but that only works if my second script is on the same server as my first script. My second script is on a different server. What I need to have the variable set in the first script and past into the second on a different server - if possible
Thanks

The only alternative if it works (dont know what you want to do...) would be using file descriptors...
