Azure Cloud Shell vs. Bash vs. JavaScript vs. openIndiana Comparison Chart

Bash is a free software Unix shell and command language. It has become the default login shell for most Linux distributions. In addition to being available on Linux systems, a version of Bash is also available for Windows through the Windows Subsystem for Linux. Bash is the default user shell in Solaris 11 and was the default shell in Apple macOS from version 10.3 until the release of macOS Catalina, which changed the default shell to zsh. Despite this change, Bash remains available as an alternative shell on macOS systems. As a command processor, Bash allows users to enter commands in a text window that are then executed by the system. Bash can also read and execute commands from a file, known as a shell script. It supports a number of features commonly found in Unix shells, including wildcard matching, piping, here documents, command substitution, variables, and control structures for condition testing and iteration. Bash is compliant with the POSIX shell standards.

OpenIndiana is an operating system from and for the illumos community, it branches from the UNIX-derived family tree, and as such it can sometimes seem quite complex. But with a little help and information, once you know the basics, you will find it actually has some of the nicest and friendliest tools around. As most Unix-derived operating system, it can be completely controlled via a Command Line Interface shell, but it also supports a windowing GUI system. From the CLI, it supports a number of different shells, the two main ones being ksh93 and Bash. It also supports the original SunOS SVR4 commands, the command and syntax famiilar to BSD users, and a large portion of the GNU userland commands that most Linux users are familiar with. You can select any or all of those different commands from your shell configuration, giving you the environment you are most happy with.
