== Suggested bashrc in [[Fish#Setting fish as default shell]] needs revision ==

This script seems to contain many unneeded parts, such as {{ic|$BASH_EXECUTION_STRING}} and {{ic|login_shell}} checks.

It also misses at least one needed safeguard: check if{{ic|$SHLVL}} is greater than 1 or 2. Without it, nested <code>nix-shell</code> will likely break.

Seems like this script was initially adapted from ArchWiki Fish page. Right now i am working to clean up the corresponding section on ArchWiki.

Please, see https://wiki.archlinux.org/title/Fish#Modify_.bashrc_to_drop_into_fish and the respective Talk page there. There you'll find rationale for everything i've mentioned in this NixOS Wiki Talk page. Also you may check latest ArchWiki edit history for Fish page (I am also @Pigeon there).

Too many users copy-paste provided snippets from wiki without understanding how it works (i've done that myself). So i propose that make this script more accurate :-) [[User:Pigeon|Pigeon]] ([[User talk:Pigeon|talk]]) 18:40, 24 January 2026 (UTC)
