Package a bash script as a snap?

Is it possible to package a bash script as a snap? If so, how can this be done?

I’ve seen the “Building your first Snap” section of https://snapcraft.io/, but it doesn’t say anything about bash.

I don’t recall ever doing it, but I don’t see why it’s not possible. I’d follow the pre-built but instead of having a source: which is an upstream binary tarball, maybe link to a directory containing your shell script. Make the apps: section point to the script inside the snap.

I’d just use the dump plugin. Put your script under a scripts/ subdirectory and have that directory as the source for the dump plugin. Remember to add stage-packages for anything your bash script calls which isn’t already in the core snap.

Thanks. That’s useful. I’ve been able to package the snap, and it runs, but it doesn’t seem to have permission to execute other scripts. This seems helpful: https://docs.snapcraft.io/build-snaps/parts
