Shell Programming and Scripting

So i have a script that is like this:

Code:

#!/bin/sh

VARA="elementary 1
elementary 2
nursery A
nursery B
highschool AZ"

echo "${ContentOfADifferentSCRIPT}" | sh

i do not have control over the script that is inside the variable "${ContentOfADifferentSCRIPT}".

however, i know that the script content of the variable ${ContentOfADifferentSCRIPT}" needs the content of the variable "${VARA}".

how do i make the ${VARA} variable available to the "${ContentOfADifferentSCRIPT}" variable when I pipe and run sh on it?

You've got two options here:
- export VARA to make the variable part of the environment
- echo "${ContentOfADifferentSCRIPT}" | VARA="$VARA" sh to define the variable locally

Third might be

Code:

 $ content='echo $aa'
 $ aa=hep                 
 $ eval $content
hep
 $

Juha

But an exit within content probably breaks things

You have an sh that runs another sh?
Then perhaps you can run the code in variable in the current sh?

Code:

eval ${ContentOfADifferentSCRIPT}

(Just seeing the previous post - with the same idea.)
