A Unix shell is both a command interpreter and a programming language. As a command interpreter, the shell provides the user interface to the rich set of GNU utilities. The programming language features allow these utilities to be combined. … Shells may be used interactively or non-interactively.
Is Unix a coding language?
Early on in its development, Unix was rewritten in the C programming language. As a result, Unix has always been closely tied to C and then later C++. Most other languages are available on Unix, but systems programming is still primarily a C/C++ kind of thing.
