+# Shell
+
+The Shell in Arch-Linux 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.
+
+## Setup
+
+- `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
