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.

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, ... |
