In computing, Bash (short for "Bourne Again SHell,") [6] is an interactive command interpreter and command programming language developed for UNIX-like operating systems. [7] Created in 1989 [ 8 ] by Brian Fox for the GNU Project , it is supported by the Free Software Foundation and designed as a 100% free alternative for the Bourne shell ( sh ...
This is a list of commands from the GNU Core Utilities for Unix environments. These commands can be found on Unix operating systems and most Unix-like operating systems. GNU Core Utilities include basic file, shell and text manipulation utilities. Coreutils includes all of the basic command-line tools that are expected in a POSIX system.
The C and Tcl shells have syntax quite similar to that of said programming languages, and the Korn shells and Bash are developments of the Bourne shell, which is based on the ALGOL language with elements of a number of others added as well. [4]
Command Prompt, a CLI shell in Windows Bash, a widely adopted Unix shell A command-line interface (CLI) is an operating system shell that uses alphanumeric characters typed on a keyboard to provide instructions and data to the operating system, interactively.

The Unix system had been written almost exclusively in C, so the C shell's first objective was a command language that was more stylistically consistent with the rest of the system. The keywords, the use of parentheses, and the C shell's built-in expression grammar and support for arrays were all strongly influenced by C.
An independent project offers syntax highlighting as an add-on to the Z Shell (zsh). [51] This is not part of the shell, however. PowerShell provides customizable syntax highlighting on the command line through the PSReadLine [31] module. This module can be used with PowerShell v3.0+, and is bundled with v5.0 onwards.
