Substituting variables in cat output

[beaunewcomb]

I have 3 files.
setvariables.sh
unprocessed.txt
process.sh


setvariables.sh just contains a list of export variables, that's all.

unprocessed.txt is an "unprocessed" file full of undefined variables.

I want process.sh to first execute setvariables.sh, then cat (or whatever would make this work) the unprocessed.txt file outputting a processed file with the variable definitions from setvariables.sh

This has to be easy... any ideas?

You could try something like:

. ./setvariables.sh
TEXT=$(<unprocessed.txt)
eval echo "$TEXT"

No idea if it'll work - but it might give you some clues, at least.

Maybe you can use parameter substitution?
