% stty erase ^?
If the character is erased, but in a funny way, then something iswrong with your tty settings. If
echoprt is set, then erased charactersare enclosed between
\ and
/.If
echoe is not set, then the erase char is echoed(which is reasonable when it is a printing character, like #).Most people will want
stty echoe -echoprt. Saying
stty sanewill do this and more. Saying
stty -a shows your current settings.How come this is not right by default? It is, if you use the right
getty.
Note that many programs (like bash, emacs etc.) have their ownkeybindings (defined in ~/.inputrc, ~/.emacs etc.)and are unaffected by the setting of the erase character.
`Getty used to do the right thing with DEL and BS but is broken now?'
Earlier, the console driver would do BS Space BS(\010\040\010)when it got a DEL (\177).Nowadays, DEL's are ignored (as they should be,since the driver emulates a vt100). Get a better getty, i.e.,one that does not output DEL.
`Login behaves differently at the first and second login attempts?'
At the first attempt, you are talking to getty. At the second attempt,you are talking to login, a different program.
On the console, or, more precisely, when not in (MEDIUM)RAW mode, use
% loadkeys mykeys.map
and under X use
% xmodmap mykeys.xmap
Note that (since XFree86-2.1) X reads the Linux settings of the keymapswhen initialising the X keymap. Although the two systems are not100% compatible, this should mean that in many cases the use of
xmodmap has become superfluous.
If, for example, you want your Backspace key to generate BackSpace(ˆH), instead of the default Delete, then
% loadkeyskeycode 14 = BackSpace%
will do.
`Why doesn't the Backspace key generate BackSpace by default?'
(i) Because the VT100 had a Delete key above the Enter key.
(ii) Because Linus decided so.
% xmodmap -e "keysym BackSpace = Delete" -e "keysym Delete = BackSpace"
Or, if you just want the Backspace key to generate a BackSpace:
% xmodmap -e "keycode 22 = BackSpace"
Or, if you just want the Delete key to generate a Delete:
% xmodmap -e "keycode 107 = Delete"
(but usually this is the default binding already).
Put in your .emacs file lines like
(global-set-key "\?" 'delete-backward-char) (global-set-key "\C-h" 'help-command)
Of course you can bind other commands to other keys in the same way.
Put in your .emacs file lines
(setq keyboard-translate-table (make-string 128 0)) (let ((i 0)) (while (< i 128) (aset keyboard-translate-table i i) (setq i (1+ i)))) (aset keyboard-translate-table ?\b ?\^?) (aset keyboard-translate-table ?\^? ?\b)
Put in your .kermrc file the lines
set key \127 \8 set key \8 \127
Normally xterm will inherit the tty modes from its invoker.Under xdm, the default erase and kill characters are # and @,as in good old Unix Version 6.If you don't like that, you might put something like
XTerm*ttymodes: erase ^? kill ^U intr ^C quit ^\ eof ^D susp ^Z start ^Q stop ^S eol ^@
in
/usr/lib/X11/app-defaults/XTerm or in
$HOME/.Xresources, assuming that you have a line
xrdb $HOME/.Xresources
in your
$HOME/.xinitrc.
Putting
*XmText.translations: #override\n\ <Key>osfDelete: delete-previous-character() *XmTextField.translations: #override\n\ <Key>osfDelete: delete-previous-character()
in your
$HOME/.Xresources helps.
The netscape FAQ, however, says:
Why doesn't my Backspace key work in text fields? By default, Linux and XFree86 come with the Backspace and Delete keys misconfigured. All Motif programs (including, of course, Netscape Navigator) will malfunction in the same way. The Motif spec says that Backspace is supposed to delete the previous character and Delete is supposed to delete the following character. Linux and XFree86 come configured with both the Backspace and Delete keys generating Delete. You can fix this by using any one of the xmodmap, xkeycaps, or loadkeys programs to make the key in question generate the BackSpace keysym instead of Delete. You can also fix it by having a .motifbind file; see the man page for VirtualBindings(3). Note: Don't use the *XmText.translations or *XmTextField.translations resources to attempt to fix this problem. If you do, you will blow away Netscape Navigator's other text-field key bindings.
When people have problems with backspace, they tend to look at their termcap(or terminfo) entry for the terminal, and indeed, there does exist a kb(or kbs) capability describing the code generated by the Backspace key.However, not many programs use it, so unless you are having problems with oneparticular program only, probably the fault is elsewhere.Of course it is a good idea anyway to correct your termcap (terminfo) entry.See also below under "The TERM variable".
FAQs
Modern terminals use "Ctrl + ?" for Backspace. Most systems will recognize the latter as Backspace these days as physical terminals have largely been replaced by terminal emulators on PCs, but you may still run into systems that haven't been upgraded and still expect "Ctrl + H."
