Hm. But how do I detect these files?

Why do you have to regenerate symlinks again? Can't you just have a bin/ directory for each version of Perl and alter the link that points to the directory, instead of creating symlinks for each of the executables under bin/?

@kazuho they are not symlinks.

I'm sure you can reproduce this on your env, but in case it isn't here's what it loos like:
> ls ~/.plenv/shims | grep zipdetails
zipdetails
zipdetails5.17.10
zipdetails5.17.11
zipdetails5.18.1
zipdetails5.18.2
zipdetails5.18.3
zipdetails5.18.4
zipdetails5.19.0
zipdetails5.19.1
zipdetails5.19.3
zipdetails5.19.9
zipdetails5.20.0
zipdetails5.20.1
zipdetails5.21.4
zipdetails5.21.7
zipdetails5.21.8
> ls ~/.plenv/versions/5.20.1/bin/ | grep zipdetails
zipdetails
zipdetails5.20.1
> zipdetails5.20.0
plenv: zipdetails5.20.0: command not found
The `zipdetails5.20.0' command exists in these Perl versions:
5.20.0
5.20.0-RC1
Because these commands exist for each perl, these shims are generated to keep track of the aggregated bin files. However this executable conflicts with plenv/perlbrew in the first place (they're there in /usr/bin for example to make sure you'll run it with the right perl version, in case you have multiple perl versions in /usr/bin).
I don't know what is the right thing to do, but an easy patch would be just ignore files that are a) known to come with perl core and b) ends with [5\.\d+\.d+]$.

Actually, i was about to go ahead and delete all these command5.* files, and found out that these are actually symlinks inside of their own perl bin.
ll ~/.plenv/versions/*/bin | grep zipdetails

It is fairly annoying, and I wonder if there's a perl build option to disable them in the first place...

That being said, this whole plenv commands including this rehash are just ported over from rbenv, and @kazuho is right that regenerating the whole files don't seem to make sense.
unless i'm stupid, what I've found out so far is that bash for loop is so slow.
I have 3716 bin files across various perl versions I have,
ls -l ~/.plenv/versions/*/bin/* | wc -l
3716
and just iterating them over in register_shims which calls register_shim is so slow. I replaced it with an inline invocation and the process is now 4 sec faster.
at this point i'm fairly convinced that I should just uninstall these dev versions and call it a day :/
