[Solved] Bash – back tick invocation blocks for ever

by


if the call to callee.sh is hanging with parameters, try executing it outside the script with parameters and check if it is hanging there as well…
Anyways, the best way of saving output (and printing it out afterwards):

result="$(./callee.sh param1 param2 param2)"
echo "${result}" <--- this should show the line breaks
