Shell

A shell is a command-line interpreter that provides a command-line interface to interact with the many unix-like system.

Change /bin/sh

The Shell in some distributions is made up by a POSIX compliant mode of bash. Problem with that is the speed. A shell like dash would be much faster. This is a guide on how to persistently change the symlink /bin/sh from bash to dash.

• yay -S dash - Install dash
• sudo ln -sfT /bin/dash /bin/sh - link /bin/sh to dash
• sudo vim /usr/share/libalpm/hooks/bash-update.hook - setup a hook to avoid bash resetting the symlink
