[IanButterworth]

Adding pkg> rm --all was discussed on slack, then this discourse post for the same with pkg> free --all

So here's all three

(jl_y3T9Rt) pkg> pin --all

ERROR: rm requires at least one package

The same can be achieved with the all_pkgs kwarg on the Pkg. variants

Can we also add something about this to the brand new CHANGELOG file? https://github.com/JuliaLang/Pkg.jl/blob/master/CHANGELOG.md.

[00vareladavid]

Should this also close #1211?

I am trying free --all on Julia 1.7.1. I have one package devd, and a few others installed properly. free --alll doesn't work - it errors on the first package saying it expects it to be pinned or tracking a path.

Is this expected behaviour / is anyone able to reproduce please? I would expect free to only free the free-able packages and ignore the rest.

[IanButterworth]

Ah, yeah we need --all to behave like any in these cases
