Allan or Dave, mind taking a look at this? We should show usage info, as rankmirrors and pacman-key do without args, instead of this silly behavior.

We never check for $1 being unset before proceeding. Probably my mistake when I did some refactoring of repo-add.

'set -u' with 'set -e'? Ugly...
Care to explain why? Using this in our cleanup scripts would have prevented the Arch repos disappearing on more than one occasion....
Because the combination of these two flags causes scripts to fail in mysterious and unexpected ways. Also, it won't save you from set but empty vars, which I suspect would be just as dangerous as unset vars in the situation you allude to. Just validate the user inputs. It makes things more obvious to an outside reader of the code, as well as consumers of the script. dave
I've got fixes for both on my 'scripts-fixup' branch
https://github.com/falconindy/pacman/commit/e99b6a131ea08829da26d62d498c33f3... https://github.com/falconindy/pacman/commit/e42d97b7370c9e30d9ae66a33f42d274...
why not:
case ${1:-""} in
which fixes the issue and leaves nounset.
