[Octave-bug-tracker] [bug #57587] Should symlinks follow physical structure or logical structure?

[Lars Kindermann]

Follow-up Comment #7, bug #57587 (project octave):

I just investigated how several shells and interpreters handle symlinks by
executing the respective equivalent to


cd symlink
pwd
cd ..
pwd


bash, dash, zsh, fish: logical (can be switched to physical)

tcsh: physical (can be switched to logical)

csh: $cwd logical, 'cd ..' physical

busybox : physical

thunar, nautilus: logical

tcl: pwd logical but 'cd ..' physical

perl, python, R, php, octave: physical

libreoffice (dialogs, fields and scripts): logical

So almost all shells implement both logical and physical maneuvering, most
default to logical behaviour but script languages typically provide no logical
maneuvering.

A nice example of a typical discussion presenting all possible strong opinions
about this topic is here:
https://github.com/fish-shell/fish-shell/issues/1957

Personally, I would love Octave to behave "logical", because getting physical
on demand would still be easy. And staying in the logical namespace is
currently impossible.
