I recently needed to collect arrow keys (and function keys etc.) in a shell script so that I could run a text graphics-style data entry system (with text entry fields, drop-down list boxes, progress bars and the like). Yes you can do all this in shell, and portably too if you're careful.
I've... (4 Replies)

I would like to configure the key combination Tux-J (Win-J) as Down Arrow, and the rest of the VIM-style movement keys as well (HKL).

Would somebody advise how arrow keys could be binded in AIX v5.3?
I could not find reasonable information online related to AIX.

Tk_InitConsoleChannels(3) Tk Library Procedures Tk_InitConsoleChannels(3)__________________________________________________________________________________________________________________________________________________NAME
Tk_InitConsoleChannels - Install the console channels as standard channels
SYNOPSIS
#include <tk.h>
Tk_InitConsoleChannels(interp)
ARGUMENTS
Tcl_Interp *interp (in) Interpreter in which the console channels are created.
_________________________________________________________________DESCRIPTION
Tk_InitConsoleChannels is invoked to create a set of console channels and install them as the standard channels. All I/O on these channels
will be discarded until Tk_CreateConsoleWindow is called to attach the console to a text widget.
This function is for use by shell applications based on Tk, like wish, on platforms which have no standard channels in graphical mode, like
Win32.
The interp argument is the interpreter in which to create and install the console channels.
NOTE: If this function is used it has to be called before the first call to Tcl_RegisterChannel, directly, or indirectly through other
channel functions. Because otherwise the standard channels will be already initialized to the system defaults, which will be nonsensical
for the case Tk_InitConsoleChannels is for.
