Why is this a problem?

enito · 2009-07-08 19:09:11

yep was a trouble, because everytime you press control+c you get the character with the action, is a disturb like you use some tools, like lftp, when you want correct something and you press control+c you get garbage..

Hi !
I use bash 4.0.33 and I have the same problem.
zsh is working great so I think it is a readline 6.0 issue but If someone could help us ....
It displays ^C (Ctrl-C) and ^Z (Ctrl-Z). Since readline handles some signals it seems that the trapped signal is redirected (and echoed) to the terminal by the signal handlers.

I can also report that when using irb the same problems happens and it is annoying! (irb also use readline)

Should I submit a bug to the readline list or is there a fix ?

Regards

This should help. Took me a while to remember where I had seen it but I found the answer.

From the Beginners Guide Appendix:

'Turn off Control Echo in Bash'

Some users may have noticed that since the readline update their terminal has been displaying ^C after ctrl+c has been pressed. While this is not a problem, it can be annoying. For any users who wish to disable this, simply add the following to /etc/profile or $HOME/.bash_profile:

stty -ctlecho

I added it to my ~/.bashrc.

I did that for bash (it works ...) Thanks for the tips but irb

But in irb it seems that there is another bug (probably irb implementation) I use ruby 1.9.1 p243
I will checkout subversion repository and compile it then give feedback.

EDIT :
Ok it works with the subversion stream see the bug report here : http://redmine.ruby-lang.org/issues/show/1118
readline 6.0 does not SEGV ... it is obscure to me ....

I think i will wait for a ruby 1.9 official release. Latest release 1.9.1-p243 (used in archlinux ) is buggy with readline 6.0
