The shells/bash port
bash-5.1.8 – GNU Bourne Again Shell
Bash is the GNU Project's Bourne Again SHell, an sh-compatible
command language interpreter that executes commands read from the
standard input or from a file. Bash also incorporates useful
features from the Korn and C shells (ksh and csh).
Bash is intended to be a conformant implementation of the IEEE POSIX
Shell and Tools specification (IEEE Working Group 1003.2).
