PROGRAM:

NAME

shelltool - run a shell (or other program) in an OpenWindows terminal window

SYNOPSIS

shelltool [ -C ] [ -B boldstyle ] [ -I command ] [ generic-tool-arguments ] [ program [
arguments ] ]

AVAILABILITY

This command is available with the OpenWindows user environment, For information about
installing OpenWindows, refer to the OpenWindows Installation and Start-Up Guide.

DESCRIPTION

shelltool is a standard OpenWindows facility for shells or other programs that use a
standard tty-based interface.

When invoked, shelltool runs a program, (usually a shell) in an interactive terminal
emulator based on a tty subwindow. Keyboard input is passed to that program. In the
OpenWindows version of shelltool, a restricted pop-up menu is available from the main
display area that allows you to enable scrolling. Selecting the Enable Scrolling option
from the restricted menu gives shelltool the full functionality of the cmdtool window,
included a larger pop-up menu from which to select options. Selecting Disable Scrolling
from the pop-up submenu will return Shelltool to its original state.

OPTIONS

-C Redirect system console output to this shelltool.

-B boldstyle Set the style for displaying bold text to boldstyle. boldstyle can be a
string specifying one of the choices for the term.boldstyle default, see
Defaults Options, below, or it may be a numerical value for one of those
choices, from 0 to 8, corresponding to the placement of the choice in the
list.

-I command Pass command to the shell. SPACE characters within the command must be
escaped.

generic-tool-arguments
shelltool accepts the generic tool arguments listed in xview(1).

USAGE

.Xdefaults File Options
You can specify a number of defaults using the options in the .Xdefaults file that effect
the behavior of shelltool. The ones of interest are those that begin with text,term, or
keyboard. See .xview(1) for more detailed information.

The Terminal Emulator
The tty subwindow is a terminal emulator. Whenever a tty subwindow is created, the
startup file ~/.ttyswrc is read for initialization parameters that are specific to the tty
subwindow.

The .ttyswrc File
The command format for this file is:

# Comment.
set variable Turn on the specified variable.
mapi key text When key is typed pretend text was input.
mapo key text When key is typed pretend text was output.

The only currently defined variable is pagemode. key is one of L1-L15, F1-F15, T1-T15,
R1-R15, LEFT , or RIGHT (see note below). text may contain escapes such as \E, \n, ^X,
etc. (ESC, RETURN , and CTRL-X , respectively). See termcap(5) for the format of the
string escapes that are recognized. Note: mapi and mapo may be replaced by another
keymapping mechanism in the future.

When using the default kernel keyboard tables, the keys L1, LEFT , RIGHT , BREAK , R8,
R10, R12, and R14 cannot be mapped in this way; they send special values to the tty
subwindow. Also, when using the default kernel keyboard tables, L1-L10 are now used by
XView. See input_from_defaults(1) and kbd(4S) for more information on how to change the
behavior of the keyboard.

It is possible to have terminal-based p special escape sequences. These escape sequences
may also be sent by typing a key appropriately mapped using the mapo function described
above. The following functions pertain to the tool in which the tty subwindow resides,
not the tty subwindow itself.

\E[1t - open
\E[2t - close (become iconic)
\E[3t - move, with interactive feedback
\E[3;TOP;LEFTt - move, to TOP LEFT (pixel coordinates)
\E[4t - stretch, with interactive feedback
\E[4;HT;WIDTHt - stretch, to HT WIDTH size (in pixels)
\E[5t - front
\E[6t - back
\E[7t - refresh
\E[8;ROWS;COLSt - stretch, to ROWS COLS size (in characters)
\E[11t - report if open or iconic by sending \E[1t or \E[2t
\E[13t - report position by sending \E[3;TOP;LEFTt
\E[14t - report size in pixels by sending \E[4;HT;WIDTHt
\E[18t - report size in characters by sending \E[8;ROWS;COLSt
\E[20t - report icon label by sending \E]Llabel\E
\E[21t - report tool header by sending \E]llabel\E
\E]ltext\E - set tool header to text
\E]Ifile\E - set icon to the icon contained in file; file must be in
iconedit output format
\E]Llabel\E - set icon label to label
\E[>OPT;...h - turn SB OPT on (OPT = 1 => pagemode), for example, \E[>1;3;4h
\E[>OPT;...k - report OPT; sends \E[>OPTl or \E[>OPTh for each OPT
\E[>OPT;...l - turn OPT off (OPT = 1 => pagemode), for .B \E[>1;3;

See EXAMPLES for an example of using this facility.

shelltool Windows

The window created by shelltool is based on the text facility that is described in the
textedit man page. The user is given a prompt at which to type commands and pop-up menus
from which to select command options.

shelltool windows support cursor motions, using an /etc/termcap entry called sun-cmd.
Command windows automatically set the TERM environment variable to sun-cmd. So, if you
rlogin(1C) to a machine that does not have an entry for sun-cmd in its /etc/termcap file,
the error message `Type sun-cmd unknown' results. To rectify this, type the command `set
TERM=sun'. Programs written using the curses(3X) or curses(3V) library packages will work
in a command window, but programs hard-coded for sun-type terminals may not. When
supporting a program that performs cursor motions, the command window automatically takes
on the characteristics of a tty window (as with shelltool(1)). When that program
terminates or sleeps, the full command window functionality is restored.

cmdtool supports programs that use CBREAK and NO ECHO terminal modes. This support is
normally invisible to the user. However, programs that use RAW mode, such as rlogin(1C)
and script(1), inhibit command-line editing with the mouse. In this case, however, tty-
style ERASE, word-kill and line-kill characters can still be used to edit the current
command line.

The shelltool Menu
The shelltool window menu is called the Term Pane menu and contains the following options
and their submenus:

Enable Page Mode
Enables page mode within shelltool .

Copy Places the highlighted text on the clipboard.

PastePuts the contents of
pointed to by the cusor.

Scrolling Enables scrolling within shelltool .

EXAMPLES

The following aliases can be put into your ~/.cshrc file:

alias header 'echo -n "\E]l\!*\E\"'

alias iheader 'echo -n "\E]L\!*\E\"'

alias icon 'echo -n "\E]I\!*\E\"'
