Linux - Capture exit code of a ruby script

Question

I have a simple ruby script which uses the abort function to exit with a non-zero exit code

#!/usr/bin/env ruby

puts "I ran"
abort "Exiting"

How can I capture the exit code when I execute this command in bash?

I have tried exit_code=./test or exit_code=ruby test to no avail.

Thanks

Answer 1

Try this:

./test
echo $?

The special shell variable $? contains the exit code of the last terminated program.

It does not matter whether your program is a ruby program. All Unix programs have an exit code which is handled alike in the starting shell.

Answer 2

The exit code of the last program that ran is stored in $?

Answer 3

You find the exit code from the previously executed command in the variable $?.
