howto spawn shell when env variable doesn't point to /bin/sh
 

Hi,

I have my environment (ENV) variable set to a shell script that used dialog and ncurses to display a graphical menu. One of the options of the menu is to spawn a shell.

When this option is chosen, the shell immediately spawns but then runs my menu again.

Is there a way I can spawn just a shell, and not run the environment variable everytime or some other way of achieving this?

How are you spawning?
What happens if you explictly spawn /bin/bash ?

Add a check in your shellscript to check current SHLVL and don't spawn the menu if SHLVL=$[${SHLVL}+1] ?

Edited my post, as I didn't understand your question the first time around. :)

Sorry bout that.

Hi,

If I explicitly call /bin/sh or /bin/ash (I am not using bash), then I can see a shell spawned for a split second, but then my menu returns.

Unspawn,

You had a great idea. I just realised though that ash doesn't support this environment variable. I am attempting to see if I can remedy that or maybe somehow create my own variable. I guess I could just set a variable in the profile before the env setting and check if its set before setting the env to the menu. I will try that.

If anyone else has any ideas, please let me know!

Clean solution. Exporting once should prolly do. Inheritance and all that.
