General :: Bind / Map Character To Alt+?
Dec 23, 2009
In programming and various terminal programs (Screen, Vim) the [, ], { and } tends to be used a lot. I'm using a Norwegian keyboard where these are placed such that I have to stretch my fingers a bit too long for whats comfortable. To make it easier I though I'd try to make alt+[some key] be one of these characters. Is there a way that I can bind, say alt+� (Norwegian letter) to '{' system wide?Btw, is such thing called binding, mapping or something else? I'm getting a bit confused by the terms...

I was messing around with the alternate character panel app and made a custom character set. I then wanted to put it on a new panel and created a new panel. I moved the character set to that panel, and then started to mess around with the panel settings (auto hide, show hide buttons, and expand, to be specific.) So far so good, until I moved the panel from the right side of the screen to the top. I already had a panel here, and it seemed not to like hiding a panel when there was already one on the top.
When the new panel hid itself, all my panels stopped responding (any clicks on them did nothing) and my processor started going at 100%. I tried a reboot and the only thing that changed is that now I can't even see my panels. I'm guessing I need to change the settings back manually through the prompt, but I don't know how to do that. I am using 10.04 and have not upgraded gnome since upgrading to 10.04.

I am attempting to set a character set of IBM850 on slackware linux for a particular application (epic5). I am using rxvt-unicode and have setup LANG/LC_*=en_US. Now if I set the encoding to IBM850 in kde's konsole program im able to display certain characters correctly. I'd rather not use IBM850 for everything; is there a way to set/alias a command for a per application execution?
I've tried things like:
LC_CTYPE=IBM850 epic5
LC_ALL=IBM850 epic5

I'm looking for a way to force my PS1 variable to a certain number of chars.
It currently looks like:
$PS1="W $"
and I'm trying to keep the same number of characters regardless of the length of current folder name.
For example, both Documents and bin would be displayed as 10 character strings, keeping the left side of my terminal the same width all of the time.

I'm reading linux device drivers,
and I'm creating a scull-like driver.
I alloc a chrdev region
with
alloc_chrdev_region(&dev,minor_number,number_of_devs);
how can i deallocate it ? I tried with
unregister_chrdev_region but it does work only for
statically allocated devices.
i want to deallocate it so that only a single major number is assigned to my driver and
cat /dev/devices | grep $dev_name
returns no more than 1 line.

I have got certain files which somehow contain abnormal character "Del" "0x7f" or 177 which represents Del. And this is causing SVN to reject these files and abruptly end the process. I need to remove those characters from the file names but am not able to. find or grep do not search the files. This is how the file looks like with ls or find code...

we have a dedicated linux server for our web hosting services which we purchased a few months ago...however the support is limited and every time we ask for assistance we are told to find the answer ourselves and pay the techies to install our solution! Anyway... we seem to have issues with character encoding on our websites - any text that isn't fully ASCII coded is outputted as funny symbols - for example:

I have a character app running on a Linux server with a telnet thin client. This app requires 3 input values that I would like to be filled in from a scale indicator that is connected via serial to the PC running this app. I feel like this is doable but not sure how. The app is running in Progress 10.1B. Currently I can see the 3 values coming from the serial port with hyperterminal but I do not want to have to rekey into the app.

I am filtering some output from gcc with grep. But if the output contains the accent character (`) I run into a problem.Then I have to press ctrl/c to get back to a prompt.
(1) Can someone tell me what is going on? I suspect that it is trying to match up the accent with another accent. But my output is from gcc and there is no control over the fact that it uses an accent and a single quote around a name.
(2) Can someone tell me how to do the grep so it does not give the ">" prompt but instead locates "xcvr" in my example?

I've read in several places that it is recommended to bind-mount /var/tmp to /tmp.This can be done by adding the following line to /etc/fstab:/tmp /var/tmp none rw,noexec,nosuid,nodev,bind 0 0How can this be beneficial? In other words why should we bind-mount /var/tmp to /tmp ?
