in most cases no extension

no extension for commands that are like tools - placed in /usr/local/bin/ or user’s folder ~/.local/bin/

but I add extension for scripts that matters where they are placed, for example ./build.sh and /mnt/my-disk/snapshot.sh

and source scripts in repo folder, such as github repo tools/src/tool-name.sh

I symlink it from bin with no extension, example: ln -sr ~/dev/gh/my-script-repo-name/my-script.sh ~/.local/bin/my-script original source has extension, but not in bin folder

makes same sound

Gento fans go brrrrr
