Subject: 29.4; eshell ls exit code
Date: Sun, 29 Dec 2024 14:33:27 +0000

Is it possible to have Emacs eshell/ls return a non-zero exit code for
errors? On my system, calling ls .... returns an error code of 2. If I
try the same command in eshell, I get similar error text ('No such file
or directory'), but the exit code is still 0.

I have not checked all built ins, but it appears some of them do support
non-zero exit codes. For example cd /does-not-exist yields an exit code
of 1 on both my system and in eshell.

Jim, can you please look into this?

Thanks.

This ended up being easier than I thought (a one-liner!). Fixed on the 
master branch in aff9261ab2a.

I think we should leave this as-is for the release branch though since 
I'm pretty sure it's been this way for ages, and I don't fully 
understand em-ls.el so there's a small risk I've made a mistake.

Whoops, forgot to mark this bug as done.
