Question

e.g. if inner.bash is simply echo a b c, and outer.bash calls inner.bash, how can the results of inner.bash be captured in a variable for user in outer.bash? It’s pretty simple but I don’t actually know how to do this.

Answer 1

inner.bash:

#! /bin/sh
echo "a b c"

outer.bash:

#! /bin/sh
x=`sh ./inner.bash`
echo "result of inner is "$x

So the basic thing are the backquotes `bla` gives you back the outcome of bla.
