- atdigg, on 10/12/2007, -0/+29I shouldn't have tried Alt+SysRq+b....
- Hindu_Wardrobe, on 10/12/2007, -0/+24Raising Skinny Elephants is Utterly Boring. :)
- coldphoenix, on 10/12/2007, -0/+22We don't.
- KhaaL, on 10/12/2007, -0/+17There's a more SysRq shortcuts, but this sequence is quite useful:
Alt+SysRq+s - sync the disk
Alt+SysRq+e - try to nicely kill processes (w. SIGTERM, wait a little bit here)
Alt+SysRq+i - kills processes with SIGKILL
Alt+SysRq+u - unmount disks (wait a bit here, too)
Alt+SysRq+b - reboot
I can remember that with "So Everything Is Unusual - Boot!"
More magic key shortcuts at http://www.developertutorials.com/tutorials/linux/magic-sysrq-050503/page1.html - burke, on 10/12/2007, -0/+10This is linux in general for the most part. It would seem you haven't read the article.
- burke, on 10/12/2007, -0/+10I think he meant <TAB>, if anyone is confused.
- zcat, on 10/12/2007, -0/+9True for everything but the alt-SysRq combos. Those are built into the kernel and truly are "Linux key combos".
- burke, on 10/12/2007, -0/+8Not near as much as you crazy apple people.
- chrisdawson, on 10/12/2007, -1/+7For those too lazy to google:
"'Raising Skinny Elephants Is Utterly Boring' is a mnemonic device for remembering a particularly important keystroke sequence in Linux. In the event of a total system freeze up, this is the failsafe way to safely reboot a near-frozen computer."
"The sequence is performed as follows: While holding Alt and SysRq, press the keys R, S, E, I, U, and then B, in sequence, leaving some time between keystrokes."
http://en.wikipedia.org/wiki/Raising_Skinny_Elephants_Is_Utterly_Boring - weijie90, on 10/12/2007, -0/+5i use Alt-Sysrq-R,S,E,I,U,B.
Raising Sleepy Rlephants Is Utterly Boring. - jedi851508, on 10/12/2007, -1/+6With TWO buttons!
Yeah, feel free to digg me down for that... but until the Mighty Mouse came out... /grumble grumble - TomFrost, on 10/12/2007, -0/+5man, I've been using Linux for over 10 years and I STILL had to Google that one. Thanks for the tip :)
- stanleyfresh, on 10/12/2007, -1/+5Ctrl+Alt+D - show desktop
- burke, on 10/12/2007, -0/+4Wow, that's great. I'm compiling Magic Sysrq back into my kernel right now.
- KhaaL, on 10/12/2007, -0/+3These shortcuts work directly with the kernel, it dosen't matter what DE or WM you're running. I tried these on Edgy Eft and I can confirm they work.
- weijie90, on 10/12/2007, -0/+3oops, typo at "elephants"
- tech42er, on 10/12/2007, -0/+3Yeah. I mapped my Windows key to the terminal. ; )
- ostracize, on 10/12/2007, -0/+2People, just map those shortcuts to a single key.
Google ~/.inputrc - mcprogrammer, on 10/12/2007, -0/+2Also, some of the combos listed under Console/terminal are for Linux (scrolling, changing consoles)
- ha1f, on 10/12/2007, -1/+3the best hotkey/shortcut: for completion.
- pauldonnelly, on 10/12/2007, -0/+2Also good to know:
Ctrl+c will kill most console apps, or even X apps run from a console. Ctrl+z suspends them, taking you back to your prompt where you can do what you like. The "jobs" command will tell you what you've got running in a particular console, and you can use "fg" and "bg" to move a job to the background or back to the foreground. See the respective man pages for more. - inactive, on 10/12/2007, -0/+2*points at the moon
http://catb.org/~esr/writings/unix-koans/gui-programmer.html - pixelbeat_, on 10/12/2007, -0/+2Pretty pictures. Nice.
Here is my linux keyboard shortcut reference:
http://www.pixelbeat.org/lkdb/ - capiCrimm, on 10/12/2007, -0/+2For terminal (meaning bash) it's useful to just realize that it's all the emacs bindings. You can actually switch to vi mode using "set -o vi", although I don't think many do. I suggest reading up on bash, some interesting things. Like "cd -" returns you to the last directory, or "^orig^replace^" replaces text, "!tex" will run the last line starting with "tex"... and tons of other stuff and programs...
- stalefries, on 10/12/2007, -1/+3Not a spelling error, Scooby Doo impression.
- CluelessTroll, on 10/12/2007, -0/+1[Ctrl]+[Alt]+[t] has become quite useful for suspending a session while making use of NX Client.
- pauldonnelly, on 10/12/2007, -0/+1This set is pretty much universal. If you Dapper install didn't have these (keep in mind, Magic SysRq may have been disabled, as might the X shortcuts) I'll eat my hat.
- leszek, on 10/12/2007, -0/+1oops all the tags are deleted ...
- leszek, on 10/12/2007, -3/+4Using gnome:
F1 menu
F2 launch application
F4 close application
You can also create custom shortcuts yourself.
Example for metacity from the unofficial ubuntu wiki:
How to enable Ctrl+Alt+Del to open System Monitor in GNOME
gconftool-2 -t str --set /apps/metacity/global_keybindings/run_command_9 "Delete"
gconftool-2 -t str --set /apps/metacity/keybinding_commands/command_9 "gnome-system-monitor" - 0KonTroL0, on 10/12/2007, -0/+1is this not dependent on your distro and what you are running? I can put overrides for these in my inittab....
- res0nat0r, on 10/12/2007, -2/+2This is the only one you really need:
set -o vi - daanyul, on 10/12/2007, -0/+0I've been finding the following commands for (re)mapping keys extremely useful recently- xmodmap, xev, xkeycaps, xbindkeys, xbindkeys-config (and also the Beryl config menu). Using a combination of those five commands, I've found I can set my keyboard bindings, including virtually all of the non-standard keys, to be pretty much anything I want. I'm running Ubuntu/Gnome/XGL/Beryl, but I'm pretty sure that the commands will work on anything with X.
- syrleb, on 10/12/2007, -0/+0thanks alot for that, they really helped, not all of them work but yeh good enough
- Modio, on 10/12/2007, -0/+0niiice
- azrael13666, on 10/12/2007, -0/+0im running ubuntu right now and everythings cool but my internet shortcut key on my laptop doesn't work. It's defined on the keyboard shortcuts panel but when I press it a window opens saying "Couldn't execute command: . Verify that command exists." Where would I go to fix that path cuz thats what seems to be the problem.
- pauldonnelly, on 10/12/2007, -0/+0This is a really good list. Just a few addenda:
The ctrl+alt+plus/minus shortcuts refer to the keypad plus and minus, not the ones next to backspace.
Also good to know are some keystrokes are usable in bash: ctrl+f/b to move by characters, ctrl+p/n to see previous commands, ctrl+d to delete a char, ctrl+h to backspace, alt+d to delete a word, alt+backspace to backspace over a word, and ctrl+d (on an empty line) to exit bash. They're much quicker than fumbling for the arrow keys. - manojisi, on 07/16/2008, -0/+01. ALT + CTRL + left / right arrow = change worksapce.
2. ALT + F1 = Start Menu
3. ALT + CTRL + Esc = switch between Desktop & Panels - burke, on 10/12/2007, -3/+1Yeah. Get it right.
- DarkRappey, on 10/12/2007, -5/+2I'm not sure which distros this is specific to, at least in Ubuntu you can configure a good deal of short-cuts in the System > Preferences > Keyboard Shortuts menu.
Also in the terminal: Edit > Keyboard Shortcuts menu.
Hope that's relevant. - sekyuritei, on 10/12/2007, -25/+3Keyboard shortcuts depend on what distro, desktop environment, window manager, etc. that you use. I know my Dapper install was different from this, whether or not I'm running Beryl with the default key mappings... No digg.
- saggygrandma, on 10/12/2007, -27/+4I didnt know you linux guys even used a mouse?
hehehehe - lesnadyk, on 10/12/2007, -25/+1There are no Linux key combos. Linux is a kernel. X-windows and X applications have key combos. Get it right
