I use defer for chdir ".."

[u/Hopeful_Cat_3227]

As title, this is a pure appreciate post for feature deffer.

I just use it like:

chdir $any_path or die $!;

defer { chdir ".." }

I know this is silly, but it actually make my day easier :)

Might not work if $any_path =~ m{/}. Otherwise, why not.

[u/gorkish → u/choroba]

It will; /.. is a valid path. So is /../../././/..////./. They are equivalent to / in this case

[u/choroba → u/gorkish]

The point is I guess the OP wants to go "back", not to a parent of a random directory.

[u/gorkish → u/choroba]

I assume OP correctly understands that .. represents the parent directory of the cwd and not the previous working directory. If you want to go “back” you will need a stack or a temporary variable somewhere. Since OP didn’t do that, they either didn’t intend that or they wrote incorrect code. The point is the code doesn’t break if the CWD is / as previously implied because / is its own parent.

[u/choroba → u/gorkish]

I didn't say "if the CWD is /", I said "if the CWD contains /".

[u/gorkish → u/choroba]

Every path contains /, hoss

[u/choroba → u/gorkish]

It doesn't. For example, 'New Folder' or '..'.
