Bash is the default shell in mac. OS, Windows Subsystem for Linux, and the majority of Linux operating systems. Bash is 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 ).
A question we ran across in our research was “How does the Bash shell work?”.

Bash is an sh -compatible command language interpreter that executes commands read from the standard input or from a file.
