'''^txt2regex$''' is a [[regular expression]] wizard that leads the user through the construction of a regular expression by asking a series of questions. The regular expression is generated in the notation used by [[awk]], [[Ed (Unix)|ed]], [[egrep]], [[Emacs]], [[expect]], [[Find (Unix)|find]], [[grep]], [[Lex programming tool|lex]], [[Lisp programming language|Lisp]], [[MySQL]], [[OpenOffice.org]], [[Perl]], [[PHP]], [[PostgreSQL]], [[Procmail]], [[Python (programming language)|Python]], [[Sed]], [[Tcl]], [[VBscript]], [[Vi]], and [[Vim (text editor)|Vim]]. It is a useful tool for users with little or no knowledge of regular expressions and so is included in several Linux distributions, including [[Debian]], [[Fedora_(operating_system)|Fedora]], [[Gentoo Linux|Gentoo]], [[Knoppix]], and [[Mandriva]], in [[FreeBSD]], and in [[Fink]] for [[Mac OS X]].
Although graphical interfaces have typically followed command line interfaces, ^txt2regex$ 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 regular expression notations. ^txt2regex$ is a [[bash script]].
