Please add a `--command` / `-c` option to `bst shell`, or similar
When running automated tests on things I'm building with BuildStream, I'd like to be able to run them in a sandbox as with bst shell
, but not interactively in a shell, e.g. similar to bash -c 'echo hello'
:
bst shell --scope run -c './run_tests.sh' example.bst
echo $?
I'd also like the return code of the command to be reported back, so it can be used to report success or failure.
