SYNOPSISshelltool [ -C ] [ -B boldstyle ] [ -I command ] [ generic-tool-arguments ] [ program [ arguments ] ]
AVAILABILITYThis command is available with the OpenWindows user environment, For information about installing OpenWindows, refer to the OpenWindows Installation and Start-Up Guide.
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.
- 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.
- shelltool accepts the generic tool arguments listed in xview(1).
.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 FileThe command format for this file is:
- 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.
- - open
- - close (become iconic)
- - move, with interactive feedback
- - move, to TOP LEFT (pixel coordinates)
- - stretch, with interactive feedback
- - stretch, to HT WIDTH size (in pixels)
- - front
- - back
- - refresh
- - stretch, to ROWS COLS size (in characters)
- - report if open or iconic by sending \E[1t or \E[2t
- - report position by sending \E[3;TOP;LEFTt
- - report size in pixels by sending \E[4;HT;WIDTHt
- - report size in characters by sending \E[8;ROWS;COLSt
- - report icon label by sending \E]Llabel\E\
- - report tool header by sending \E]llabel\E\
- - set tool header to text
- - set icon to the icon contained in file; file must be in iconedit output format
- - set icon label to label
- - turn SB OPT on (OPT = 1 => pagemode), for example, \E[>1;3;4h
- - report OPT; sends \E[>OPTl or \E[>OPTh for each OPT
- - turn OPT off (OPT = 1 => pagemode), for .B \E[>1;3;
See EXAMPLES for an example of using this facility.
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 .
- Places the highlighted text on the clipboard.
- PastePuts the contents of
- pointed to by the cusor.
- Enables scrolling within shelltool .
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\"'
