How do I write my trap statement in shell script to ignore SIGINT.Reason being is that the script is used to update records in database. I want to avoid inconsistency in database when user presses Ctrl-C .The result should be
1. Totally ignore Ctrl-C (SIGINT) when user presses Ctrl-C
2. Continue with the rest of processing
I've done some hunting on this and other forums as well as my own system and have come up dry. I have a SLES10 box where root is using the Korn shell as the default. There was a lot of system configuration done by the vendor of the app that sits on this box and one of the "features" is that Ctrl+C no longer sends a SIGINT. I just get "^C" when I try. Needless to say, I'd like to redefine this so that I can kill commands/scripts without the need to manually whack the PID. Where is the Ctrl+C defined and what steps do I take to redefine it to its default behavior?

View 1 Replies View RelatedI often use the key combination ctrl + shift + F10 in my editor, and sometimes I mistakenly hit ctrl + alt + F10 which instantly transports me to a black screen with nothing but a cursor resulting in my having to reboot. I have no idea what the purpose of this key binding is but I want to get rid of it. I have looked in 'keyboard shortcuts' but there is none listed for ctrl + alt + F10. How do I disable this once and for all?

So I just "pkill nautilus" to restore the previous nautilus session (even if we can't control nautilus window session manually). But there are still a few things that could be improved for Nautilus. So for now, can we disable CTRL+Q shortcut for Nautilus?

View 6 Replies View RelatedWhen I press Ctrl-C in any pseudoterminal (xterm, gnome-terminal, rxvt, text console and SSH) in Karmic Koala, the string ^C gets echoed to the terminal in Ubuntu Karmic Koala. This hasn't happened in Ubuntu Jaunty Jackalope. I'd like to get rid of the extra ^C. Example:

How to disable Ctrl W shortcut in Firefox ?
Firefox does not provide any tool to do that. I am using gnome and Fedora 11. I tried the extension "Keyboard Shortcuts 0.1" it does nothing.
I can't switch to shell with ctrl+alt+F1. The screen gets completely blank and nothing happens - though I can switch back to the GUI by pushing ctrl+alt+F7 again.I really miss having this option!

Code:
RevBackup.sh <options> <source> <target>
The problem I'm having is that the source and target might contain spaces in the path. ie. /home/eRJe/My Documents
I would like the script to ignore " " (backslash-space) as being a delimiter. how could I do this without stopping a normal space from being a delimiter?
I could do this with IFS. But so far I have only found info about setting a delimiter and not to "ignore" one
How do I create a launcher/shortcut on Gnome desktop, which starts a Terminal window and executes a shell script?The script should execute as if I started the script manually, i.e. if I abort the script by pressing CTRL + C, the script should terminate but the terminal window should remain on screen.If I create the shell script launcher/shortcut using the �straight forward �Create Launcher� method�, the terminal window also closes when I hit CTRL + C

I'm studying an OS programming book, in particular network sockets. I have two questions(2nd one is down at the bottom). There is something I don't quite understand. What if this piece of code, which sets sigpipe's default action to ignore and opens a socket:

return -1;

I am trying to create a shell script similar to ls, but which only lists directories. I have the first half working (no argument version), but trying to make it accept an argument, I am failing. My logic is sound I think, but I'm missing something on the syntax.

Is there some type of functional way to read things in the Python shell interpreter similar to less or more in the bash (and other) command line shells?
Example:
Code:
>>> import subprocess
>>> help(subprocess)

[pages of stuff to read]
...
I'm hoping so as I hate scrolling and love how less works with simple keystrokes for page-up/page-down/searching etc.

After about one second, i can continue working as usual. Changing Tabs by just clicking on one does not freeze anything...Maybe some of you would think now if I am crazy because of complaining about such a little thing, but it is really annoying if you are used to work fluently with ff.Edit:I today noticed, that not only shortcuts in firefox, but all Hotkeys freeze my mouse for a second. For examle ctrl+c, ctrl+v, super+e or anything else.Do you have any Idea what causes this behaviour? Reinstalling ubuntu didn't change anything

View 3 Replies View RelatedI just spent a few days ripping out all the broken/buggy apps that are in the opensuse 11.2 official repos so I can finally get working software(openoffice, thunderbird, wine, eclipse, rubygems, rails, and a few others required getting the "official" versions from their respective websites to avoid strange behavior and outright broken functionality).
All of which makes updating more annoying and time-consuming. Why are opensuse packages so different anyway? Anyway, the last thing that I have noticed to fix is Konsole. For some really bizarre reason ctrl+z and ctrl+c do not work without a third keystroke: enter.Maybe this is something new with the KDE team, since they seem bent on making simple things that already work more complex, but given my experience with crappy packages in the suse repos, I am thinking this is the problem. I have looked over all the config settings that I can find and nothing fixes this affront to productivity.
