It apparently reads stuff from /etc/paths.d/ (and also for man stuff, but I
don't really care about that today, mostly things I want to execute)
The current value returned by /usr/libexec/path_helper -s is:
PATH="/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/TeX/texbin:/usr/local/MacGPG2/bin:/Library/Apple/usr/bin:/Users/pierre/.gem/ruby/3.0.0/bin:/Users/pierre/.rubies/ruby-3.0.0/lib/ruby/gems/3.0.0/bin:/Users/pierre/.rubies/ruby-3.0.0/bin:/opt/homebrew/bin:/Users/pierre/.sdkman/candidates/scala/current/bin:/Users/pierre/.sdkman/candidates/sbt/current/bin:/Users/pierre/.sdkman/candidates/leiningen/current/bin:/Users/pierre/.sdkman/candidates/kotlin/current/bin:/usr/local/sbin:/Users/pierre/.cargo/bin"; export PATH;
Clearly there's some custom stuff in there (rubies, sdkman), not sure how these
were able to install stuff somewhere to have them detected by path_helper.
The content of my /etc/paths.d is:
$ ll /etc/paths.d/
total 24
-rwxr-xr-x 1 root wheel 23B Dec 11 20:01 100-rvictl
-rw-r--r-- 1 root wheel 23B Jan 24 2020 MacGPG2
-rw-r--r-- 1 root wheel 22B Jan 19 17:46 TeX
and /etc/paths:
$ less /etc/paths
/usr/local/bin
/usr/bin
/bin
/usr/sbin
/sbin
I found out about this because I wanted to prepend my arm64 brew directory
(/opt/homebrew/bin) to my path, but doing so in ~/.zshenv was ignored.
Turned out that it's because it was running before /etc/zprofile, which runs
path_helper and was overriding my stuff:
