Bug#452922: bash: Some key sequences, such as \C-@, do not work in a key binding

But in my case it fail both with Xorg and without Xorg (in tty1,tty2 ..) I don't know if I should open a new issue, I choose this bug because the title Some key sequences, such as XX, do not work ... It is courious: With ALT key: \e# works \e@ doesn't works Both # and @ has to be produced by ALT-GR (+3 or 2) in my keyboard, so ALT and ALT-GR are being recognized ok. Regards,

retitle 452922 bash: \C-@ does not work in a key binding; some key sequences require the longer Control-$key syntax quit Javier Barroso wrote: All that links seems to talk about X issues. Are you sure? http://bugs.debian.org/326200#135 seems to be discussing the Linux console driver. [...] I don't know if I should open a new issue, I choose this bug because the title Some key sequences, such as XX, do not work ... Yes, please do open a new bug describing your set of symptoms in full. You can see what character sequence each keystroke produces by preceding the keystroke with control+v, if you want to track down whether the bug is in the console driver that produces the character sequences or bash which recognizes them.

It is courious: With ALT key: \e# works \e@ doesn't works This is true in X terminals (xterm and gnome-terminal) But without X, neither work (not \e# and not \e@ when I use ALT like \e). But ALT-f and ALT-b work. So maybe the ALT-GR key has relation with the fail. When I use ESC it (@ and #) works. Sorry again for the fast reply Regards,
Bug#452922: bash: Some key sequences, such as \C-@, do not work in a key binding
Package: bash Version: 3.1dfsg-8 Severity: normal I wanted to use set-mark as part of a readline key binding. One simple example I tried, which should have worked: bind 'Control-v: [EMAIL PROTECTED]\C-x\C-x' This should make Control-v insert an at the end of the line but leave the cursor in the current position. However, it does not work. At first I thought that the set-mark command would not work in a key binding. However, I discovered that I could bind another key to set-mark, and that key would work: bind '\C-x\C-m: set-mark' bind 'Control-v: \C-x\C-m\C-e\C-x\C-x' I furthermore discovered that if I bound some other function or string to C-@, it would not work in a macro either: bind '\C-@: at' bind 'Control-v: \C-@' Finally, I discovered that some key sequences only work if bound via the longer Control-$char syntax, and others only work if bound via \C-$char. For instance, Control-v only works if bound as Control-v; if bound as \C-v it will continue to point to quoted-insert (both in a key binding and interactively). Control-@, on the other hand, only works if bound as \C-@; if bound as Control-@, it will continue to point to set-mark (interactively; it does not work either way in a key binding). The eventual goal, which I managed to achieve after these various workarounds: # Make Control-v paste, if in X and if xclip available if [ -n $DISPLAY ] [ -x /usr/bin/xclip ] ; then # Work around a bash bug: \C-@ does not work in a key binding bind '\C-x\C-m: set-mark' # The '#' characters ensure that kill commands have text to work on; if # not, this binding would malfunction at the start or end of a line. bind 'Control-v: #\C-b\C-k#\C-x\C-?\$(xclip -o -selection c)\\e\C-e\C-x\C-m\C-a\C-y\C-?\C-e\C-y\ey\C-x\C-x\C-d' fi - Josh Triplett -- System Information: Debian Release: lenny/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 2.6.22-3-amd64 (SMP w/4 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Versions of packages bash depends on: ii base-files4.0.2 Debian base system miscellaneous f ii debianutils 2.28 Miscellaneous utilities specific t ii libc6 2.7-1 GNU C Library: Shared libraries ii libncurses5 5.6+20071103-1 Shared libraries for terminal hand bash recommends no packages. -- no debconf information -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.
