<code>wish</code> is [open-source](/source/open-source_software) under the [BSD License](/source/BSD_licenses), and is currently part of the [Tcl/Tk](/source/Tcl%2FTk) programming suite.{{citation needed|date=July 2021}}

== Usage ==
<code>wish</code> can be run without parameters. Then the <code>%</code> prompt is displayed and the interpreter awaits for commands entered interactively by the user. An empty window is opened in which the widgets created by user commands are displayed. This mode is suitable for experimenting.

More often <code>wish</code> is run with a name of a file containing a Tcl/Tk script as a parameter. It is also possible to run directly Tcl/Tk scripts; in [Unix](/source/Unix) using the [shebang](/source/Shebang_(Unix)) construction; in [Windows](/source/Windows) by associating the <code>.tcl</code> extension with the wish program.
