How to import a variable from a (ba)sh-script?

Question

I'd like to do something like this:

from ./script.sh import VARIABLE # <-- python style

(without changing script.sh)

• doublesharp: this is not possible as you have described it. you could export the variable, but it would likely require modifying your script.
• shx2: is the importing script python or bash?

Answer 1

Not exactly the same thing, but this works:

source ./script.sh
echo "VARIABLE=${VARIABLE}."

Shorter form:

. ./script.sh
echo "VARIABLE=${VARIABLE}."

This might not be desired as this will execute any code that is not in functions inside script.sh.
