NAME

       wish - Simple windowing shell

SYNOPSIS

       wish ?fileName arg arg ...?

OPTIONS

       -colormap new       Specifies  that  the window should have a new private colormap instead
                           of using the default colormap for the screen.

       -display display    Display (and screen) on which to display window.

       -geometry geometry  Initial geometry to use for window.  If this option is specified,  its
                           value  is  stored in the geometry global variable of the application's
                           Tcl interpreter.

       -name name          Use name as the title to be displayed in the window, and as  the  name
                           of the interpreter for send commands.

       -sync               Execute  all  X  server  commands  synchronously,  so  that errors are
                           reported immediately.  This will result in much slower execution,  but
                           it is useful for debugging.

       -use id                                                                                    │
                           Specifies  that  the main window for the application is to be embedded │
                           in the window whose identifier is id, instead of being created  as  an │
                           independent  toplevel window.  Id must be specified in the same way as │
                           the value for the -use option for toplevel widgets  (i.e.   it  has  a │
                           form like that returned by the winfo id command).

       -visual visual      Specifies  the  visual  to use for the window.  Visual may have any of
                           the forms supported by the Tk_GetVisual procedure.

       --                  Pass all remaining arguments through to  the  script's  argv  variable
                           without  interpreting  them.   This  provides  a mechanism for passing
                           arguments such as -name to a script instead of having  wish  interpret
                           them.

DESCRIPTION

       Wish  is  a  simple  program consisting of the Tcl command language, the Tk toolkit, and a
       main program that reads commands from standard input or from a file.  It  creates  a  main
       window  and  then processes Tcl commands.  If wish is invoked with no arguments, or with a
       first argument that starts with ``-'', then  it  reads  Tcl  commands  interactively  from
       standard  input.  It will continue processing commands until all windows have been deleted
       or until end-of-file is reached on standard input.  If there exists a file .wishrc in  the
       home  directory  of  the user, wish evaluates the file as a Tcl script just before reading
       the first command from standard input.

       If wish is invoked with an initial fileName argument, then fileName is treated as the name
       of  a  script file.  Wish will evaluate the script in fileName (which presumably creates a
       user interface), then it will respond to events  until  all  windows  have  been  deleted.
       Commands  will  not  be  read  from  standard  input.  There is no automatic evaluation of
       .wishrc when the name of a script file is presented on the  wish  command  line,  but  the
       script file can always source it if desired.

OPTIONS

       Wish  automatically  processes  all  of  the command-line options described in the OPTIONS
       summary above.  Any other command-line arguments besides these are passed through  to  the
       application using the argc and argv variables described later.

APPLICATION NAME AND CLASS

       The  name  of  the application, which is used for purposes such as send commands, is taken
       from the -name option, if it is specified;  otherwise it is taken from fileName, if it  is
       specified,  or from the command name by which wish was invoked.  In the last two cases, if
       the name contains a ``/'' character, then only the characters after  the  last  slash  are
       used as the application name.

       The class of the application, which is used for purposes such as specifying options with a
       RESOURCE_MANAGER property or .Xdefaults file, is the same as  its  name  except  that  the
       first letter is capitalized.

VARIABLES

       Wish sets the following Tcl variables:

       argc           Contains  a count of the number of arg arguments (0 if none), not including
                      the options described above.

       argv           Contains a Tcl list whose elements are the arg arguments that follow  a  --
                      option  or  don't  match  any of the options described in OPTIONS above, in
                      order, or an empty string if there are no such arguments.

       argv0          Contains fileName if it was specified.  Otherwise,  contains  the  name  by
                      which wish was invoked.

       geometry       If  the  -geometry  option  is  specified,  wish copies its value into this
                      variable.  If the variable still exists after fileName has been  evaluated,
                      wish  uses  the  value  of the variable in a wm geometry command to set the
                      main window's geometry.

       tcl_interactive
                      Contains 1 if wish is reading  commands  interactively  (fileName  was  not
                      specified and standard input is a terminal-like device), 0 otherwise.

SCRIPT FILES

       If you create a Tcl script in a file whose first line is
              #!/usr/local/bin/wish
       then you can invoke the script file directly from your shell if you mark it as executable.
       This assumes that wish has been installed in the default location in  /usr/local/bin;   if
       it's  installed  somewhere  else then you'll have to modify the above line to match.  Many
       UNIX systems do not allow the #! line to exceed about 30 characters in length, so be  sure
       that the wish executable can be accessed with a short file name.

       An even better approach is to start your script files with the following three lines:
              #!/bin/sh
              # the next line restarts using wish \
              exec wish "$0" "$@"
       This  approach  has  three advantages over the approach in the previous paragraph.  First,
       the location of the wish binary doesn't have to be hard-wired into the script:  it can  be
       anywhere  in  your  shell  search path.  Second, it gets around the 30-character file name
       limit in the previous approach.  Third, this approach will work even if wish is  itself  a
       shell  script  (this  is done on some systems in order to handle multiple architectures or
       operating systems:  the wish script selects one of several binaries to  run).   The  three
       lines  cause  both sh and wish to process the script, but the exec is only executed by sh.
       sh processes the script first;  it treats the second line as a comment  and  executes  the
       third line.  The exec statement cause the shell to stop processing and instead to start up
       wish to reprocess the entire script.  When wish starts up, it treats all  three  lines  as
       comments,  since  the  backslash at the end of the second line causes the third line to be
       treated as part of the comment on the second line.

       The end of a script file may be marked either by the physical end of the medium, or by the │
       character,  '\032'  ('\u001a',  control-Z).  If this character is present in the file, the │
       wish application will read text up to but not including  the  character.   An  application │
       that  requires  this  character  in  the  file  may  encode  it  as ``\032'', ``\x1a'', or │
       ``\u001a''; or may generate it by use of commands such as format or binary.

PROMPTS

       When wish is invoked interactively it normally prompts for each command with ``% ''.   You
       can  change  the prompt by setting the variables tcl_prompt1 and tcl_prompt2.  If variable
       tcl_prompt1 exists then it must consist of a Tcl script to output a  prompt;   instead  of
       outputting  a  prompt  wish  will  evaluate  the  script  in  tcl_prompt1.   The  variable
       tcl_prompt2 is used in a similar way when a newline is typed but the current command isn't
       yet complete; if tcl_prompt2 isn't set then no prompt is output for incomplete commands.
