It is a useful tool for users with little or no knowledge of regular expressions and so is included in several Linux distributions, including Debian, Fedora, Gentoo, Knoppix, and Mandriva, in FreeBSD, and in Fink for Mac OS X. Although graphical interfaces have typically followed command line interfaces, ^txt2regex$ is unusual in providing a command line interface for a function usually, and previously, provided by means of a graphical user interface. It is also unusual in interacting with the user to facilitate the use of what is generally regarded as a technical tool unsuitable for naive users and in supporting multiple re ...

A version is also available for Windows 10 and Windows 11 via the Windows Subsystem for Linux. It is also the default user shell in Solaris 11. Bash was also the default shell in versions of Apple macOS from 10.3 (originally, the default shell was tcsh) to the 2019 release of macOS Catalina, which changed the default shell to zsh, although Bash remains available as an alternative shell. Bash is a command processor that typically runs in a text window where the user types commands that cause actions. Bash can also read and execute commands from a file, called a shell script. Like most Unix shells, it supports filename globbing (wildcard matching), piping, ...
