Ubuntu Manpage: wish - Simple windowing shell

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 2
Specifies that the main window for the application is to be embedded in the window 2
whose identifier is id, instead of being created as an independent toplevel window. 2
Id must be specified in the same way as the value for the -use option for toplevel 2
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" ${1+"$@"}
       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, 2
       '\032'  ('\u001a',  control-Z).  If this character is present in the file, the wish application will read 2
       text up to but not including the character.  An application that requires this character in the file  may 2
       encode  it  as ``\032'', ``\x1a'', or ``\u001a''; or may generate it by use of commands such as format or 2
       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.
