Dash
POSIX-compliant minimal shell.
Dash is a small, fast POSIX shell descended from the NetBSD ash. On Debian and Ubuntu it is the /bin/sh linked at install time — running shell scripts under Dash rather than Bash for boot-time speed and POSIX strictness.
Install
Debian/Ubuntu: ships as /bin/sh Fedora: sudo dnf install dash Arch: sudo pacman -S dash
