Bash
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.

Bastillion
Bastillion is a web-based SSH console that centrally manages administrative access to systems. Web-based administration is combined with the management and distribution of users' public SSH keys. Key management and administration are based on profiles assigned to defined users. Administrators can log in using two-factor authentication with Authy or Google Authenticator. From there they can manage their public SSH keys or connect to their systems through a web shell. Commands can be shared across shells to make patching easier and eliminate redundant command execution. Bastillion layers TLS/SSL on top of SSH and acts as a bastion host for administration. Protocols are stacked (TLS/SSL + SSH) so infrastructure cannot be exposed through tunneling/port forwarding. Also, SSH key management is enabled by default to prevent unmanaged public keys and enforce best practices. Bastillion is available for free use under the Prosperity Public License.
