Description:
POSIX-compliant shell
The Debian Almquist Shell (dash) is a POSIX-compliant shell derived from ash. . Since it executes scripts faster than bash, and has fewer library dependencies (making it more robust against software or hardware failures), it is used as the default system shell on Debian systems.
