Tilda key not working in terminal only

[tliimfee]

Hey all,

I'm using Ubuntu 12.04 with the awesome window manager.
I've been playing around with adding new fonts and getting a nice color scheme to work but now the tidal key doesn't work in terminal. It works in gedit and other applications (example ~~~~~~~~~) but in terminal and subsequently <strike>vim</strike> I can't use it.

Can anyone help me solve this problem? Why did this happen? Where can I go to fix the problem?

Update:
It works in vim, which is running through the terminal. I just isn't working in terminal.

[tliimfee]

I'd greatly appreciated any help people would be able to provide or any suggestions as to why this is happening.

[tliimfee]

I'm not sure if this helps but the profile I'm currently using for my gnome-terminal as found in .gconf is as follows

Hi and welcome to the Ubuntu Forums :-)

Please don't repeat your plea for help more than once every 24 hours! Then it is enough to post a new reply with the text 'bump'.

I can get the tilde character pressing the F12 key with some different keymaps. Try that as a starter!

What keymap are you using (what language)?

You can find it out with the following command

setxkbmap -query
and change it (set it) with for example

setxkbmap us

setxkbmap de

setxkbmap es

I'd greatly appreciated any help people would be able to provide or any suggestions as to why this is happening.Are you aware that the "~" key is interpreted by the shell as a synonym for $HOME and not passed through to subsequent layers?

Try entering "ls ~" at a command prompt; expect to see a listing of all files in your home directory as a result. If you do, then things are working as designed...

[tliimfee]

Hey thanks so much for the replies and sorry about repeating the post.

My current keymap is set to the correct language,

rules: evdev
model: dell101
layout: gb

and this is confirmed as every other application correctly interrupts ~,@ and " etc.

I am also aware that ~ is shorthand for $HOME.
The main issue is that the ~ character itself is not displayed.

ls ~
is shown in the terminal as

ls
and list the files in the current directory, not the home directory.

ls $HOME
works as expected.
Also any scripts that I write which use ~ do not run correctly as the ~ is omitted when they are executed and the character ~ cannot be copied and pasted into the terminal.

[steeldriver]

do you have any 'stty' commands in your .profile or .bashrc files?

[sudodus]

What happens when you press the F12 key (can you see anything in the terminal window)?

[schragge]

do you have any 'stty' commands in your .profile or .bashrc files?+1. I have this alias defined, it always helps when the terminal gets messed up:


alias c='reset; stty sane; clear'

[tliimfee]

F12 doesn't display any character.
I don't have any stty commands in .profile or .bashrc
And the commands

reset; stty sane; clear
didn't fix the problem.

[sudodus]

F12 doesn't display any character.
I don't have any stty commands in .profile or .bashrc
And the commands

reset; stty sane; clear
didn't fix the problem.
I don't know why this is happening.

- Did the tilde key work in the terminal before?

- What terminal program are you running? Check at

Help -- About

- Does tilde work in a text screen, that you get pressing the hotkey combination
ctrl + alt + F1

- What shell are you running (bash, or some other shell)? Check with

echo $SHELL

- What happens if you paste a tilde character into a terminal window? Will it be displayed or not? Will it work as an alias for $HOME?

- Have you created a hotkey, that intercepts tilde?

- Will it work in your computer with another OS (Windows, Ubuntu booted from the install CD, or is your computer an Apple product)?

[tliimfee]

The tilde key did work before in terminal, it just doesn't now.
Help returns:

GNOME Terminal
3.4.1.1

With Ctrl+alt+F1 tilde does not work when I am logged into the terminal, however it does work if I am trying to use ~ in the user name.


echo $SHELL returns
/bin/bash

If I paste ~ into the terminal it is not shown and doesn't take up a character space.
$HOME works but I don't know if ~ is working correctly because I can never execute it.

I'm dual booting with windows 7 and the ~ button works fine in that. It seems to just not be working in the terminal in Ubuntu.

[sudodus]

So it seems that ~ is not working for you in bash, but works at your login (and in programs).

What happens when you boot your computer from your Ubuntu install CD/USB drive? I guess it works there.

I think that some installed program is intercepting ~ for you. Can you think of any program that you have installed recently (or at the time when you lost ~)? Or have you installed or changed a hotkey?

[tliimfee]

It works from a boot disk, and I've tried re-installing gnome-terminal and using konsole but the problem is still there.
The only changes I think I've made have to do with the terminal color pallet, vim plugins and adding a new font.
I'm not sure how any of them could have done this.

Is there a way I can find which process is listening for/grabbing the key action?

[matt_symes]

Hi

Do you get the same behaviour in xterm ?

Kind regards

[tliimfee]

Yes I get the same behavior in xterm.

[matt_symes]

Hi

Can you post all your bash config files please.

Kind regards

[schragge]

Does it work in /bin/dash? Enter dash from a terminal with

sh

Exit from it with Ctrl+d or

exit

[tliimfee]

The ~ does work inside dash.

Hi

Can you also post

/etc/bash.bashrc and ~/.bash_aliases and /etc/bash_completion

I may be wrong but this does look like a bash problem.

Kind regards

Hi

I can't see any obvious immediately but i will continue thinking.

My advice is to use zsh anyway. It's a better version of bash.


sudo apt-get install zsh


sudo chsh -s /bin/zsh <user_name>

It would be interesting to see if you get the same behaviour using zsh in xterm and gnome-terminal as you do in bash.

Kind regards

[schragge]

If you have ~/.bash_completion and/or ~/.inputrc then please post them, too.

It would be interesting to see if you get the same behaviour using zsh in xterm and gnome-terminal as you do in bash.

I switched to zsh and the tilde key displays and works fine.
I would prefer to say in bash though so if you do think of anything please let me know, and thanks for the help.

I don't have a ~/.bash_completion file.

Could this be a readline-related issue? Do you have ~/.inputrc? Can you enter ~ in other programs that use readline like e.g. bc?

[tliimfee]

The ~.inputrc file is:


"\e[": skip-csi-sequence

~
~
~

and tilde doesn't work in bc, it doesn't work in ipython either.

If these


~
~
~
are actually in ~/.inputrc, and not simply the result of pasting from vim, then remove them.

Hi

Good call @schragge (http://ubuntuforums.org/member.php?u=1783515)

That's what it almost certainly will be.

Kind regards

Yes the ~'s were in the file, and I took them out and now everything works.

Thanks to everyone for the help, the problem is fixed.

I'll mark the issue as answered,
but do you know why this broke the ~ button?

[schragge]

~/.inputrc redefines keys on your keyboard to call some readline functions. The first line,

"\e[": skip-csi-sequence is there to prevent inserting stray characters when accidentally pressing unbound keys that generate long escape sequences, like function keys. You probably copied it into ~/.inputrc from some example showing the vim window together with extra ~ lines. The tilda key thus got redefined to do nothing.

Yes, good call :KS
