Continuing a script on a new subshell

dpillay · 05-29-2004, 02:15 PM

Hello ppl,

Well, here's my problem, consider that I'm running a script on a shell, which after a chroot opens a new subshell, what I want here is for my original script to continue running on this new subshell. Is this possible?

Thank you for your time,
dinesh.

Why so difficult?
When the chrooted subshell is running, the original will wait until the subshell exits, I suppose? (i.e. the subshell doesn't run in the background). Then why not have two scripts. The first one:

Code:

#!/bin/bash
echo "first part"
chroot /some/dir /path/to/secondscript.sh

and the second:

Code:

#!/bin/bash
echo "second part: chrooted"

I was thinking of suggesting something along those lines as well. If the two processes need to "communicate", then you might have to put in some sort of temporary file. For instance, if you want the new shell to inherit some variables, then the first script (before the chroot) should dump whatever variables the second script needs in a file that's accessible in the chroot environment. I would think formating it like:

variable_name=value

would be the simplest since you could simply "source" it from the second script.
