wish - interface to the Tk graphics toolkit
The wish command provides a command line interface to the Tk graphics toolkit. A Tk module is first loaded and initialized. Then input is packaged into Tk commands and sent to that module. The input should be in the format of Tk commands as specified in tk.
Input is first taken from the files, if any, named as command line arguments; thereafter, commands are read from standard input.
Input sequences consisting of a backslash, \, followed by an n, t, b, or \ are converted into newline, tab, blank, and backslash, respectively.
