Sorry for the title, I really can't explain better. I'm learning shell programming.
I'm trying to detect if Composer has a script named "post-install-cmd". To do that, one can call composer run-script --list (documentation). So i pipe that command to grep -q inside a conditional.
When I run this inside a Docker layer (distribution is Debian-based), i only get an error when calling composer run-script --list inside the conditional:
RUN set -eux; \
if [ -f composer.json ]; then \
composer dump-autoload --no-dev --classmap-authoritative; \
# This is working fine, a list is returned (see log)
composer run-script --list; \
# This gives me an error (Unable to write output)
if composer run-script --list | grep -q post-install-cmd; then \
echo "Script was found!"; \
fi; \
fi
