The word ''shell'' has various meanings. The most common use of the word, on Unix, is a script interpreter implementing some language, and intended to be used interactively (in what some call ''command line'' mode) or by providing a script in a file and then executing it (a mode sometimes called ''batch'') by a user. Another more general definition is "The application that enables the user to navigate the file system and start applications." This definition also includes ''graphical shells'' like the [CDE] and [KDE] environments, the Windows Explorer or the MacOS Finder. While technically, [tclsh] and [wish] applications are shells, in the first use of the word, Bourne, [ksh], [csh]/tcsh, [bash], zsh etc. are more commonly thought of as shells than are tclsh or wish. See [Unix shells] for more discussion of this use of the word. The wiki page [exec magic] covers the topic of what type of first line ''magic'' one should put so that tclsh or wish (or whatever) gets invoked with the appropriate arguments. ---- http://en.wikipedia.org/wiki/Comparison_of_computer_shells discusses a comparison of various command line shells. Perhaps there is some tcl comperable add-on which would compare seriously to the others listed? ---- See [Invoking tclsh or wish from Bourne Shell] ---- itcl has a base widget called a ''shell'': [http://incrtcl.sourceforge.net/iwidgets/iwidgets/shell.gif] Docs can be found at http://incrtcl.sourceforge.net/iwidgets/iwidgets/shell.html and http://purl.org/tcl/home/man/iwidgets3.0/shell.n.html ---- [Category Glossary] [Category Command], a part of [incr Widgets]
