Now I connect usb keyboard to my machine, and I would like to know how I can get device file name of this usb keyboard. I know it is /dev/input/event# file,but which event# file? I tried to do [dmesg | grep usb] , but kernel message don't tell me what I would like to know.
View 1 RepliesI've bought an X10 Home Automation USB interface: the CM15.
This is the information lsusb gives:
skerit@KIP-DU-SKER:~$ lsusb Bus 008 Device 002: ID 0bc7:0001 X10 Wireless Technology, Inc. ActiveHome (ACPI-compliant)
But this tells me nothing about where the device file is! How can I find that, or create one myself?
I'm guessing the answer to my question is in manipulating the kernel command line. But with what arguments? (and does the kernel have it's own fonts to be used on a FB device?)
The host is a ARM9 based embedded system with a 1-bit LCD screen.

I have a Linux (Kubuntu) system with a large (~20Gb) file which I would like to mess with. Specifically, I want to copy the entire contents of another large file (~12Gb) to the middle of this file, and keep the bits of the file which are not overwritten.This is what I want to happen, with the text between the pipes representing file contents:Before:
outfile: |abcdefghijklmnopqrstuvwxyz|
infile: |123456789|

Everything in Linux is a file, right? And everything can be represented by a file? Is there some way I could create a block device file that represents (i.e., provides an interface to) this image file? If so, then I could use fdisk on the device file to split it into partitions, format the partitions, and then mount them as directories. I could create a file system within a file system, which would be fun.

Device/Special file Clairification Requested.I'm reading a short article on Device/special files because it is related to VFS. This article has this paragraph that has to many pronouns in it to get an understanding of. URL..."In short, a device file (also called as a special file) is an interface for a device driver that appears in a file system as if it were an ordinary file. This allows software to interact with the device driver using standard input/output system calls, which simplifies many tasks."
What does a Device file have to do with the Application and the Driver communicating? Wouldn't the order of data transfer be , Application to driver and then to Device file?
Let's say I have a joystick in `/dev/input/js0`, how do I find out which device is it on `/sys/bus/usb/devices/`?

The Completely Fair Queuing (cfq) scheduler in Red Hat Enterprise Linux 5appears to have worse I/O read performance than in version 4. It appears as though the Completely Fair Queuing I/O scheduler (cfq) has a regression and thus exhibits reduced read-side throughput which can affect performance for both local and NFS mounted file systems.
One way to mitigate this is to set the cfq's slice_idle parameter to zero. To change this value, execute the following command echo 0 > slice_idle in the /sys/block directory appropriate for your situation, as shown below:
echo 0 > /sys/block/hda/queue/iosched/slice_idle
We are using NFS file systems in RHEL 5.3. I would like to know how to find which /dev/Device is being used by the NFS file systems, so that I could try setting the slice_idle to '0' to see if there is any difference in performance? In /etc/fstab I only see the actual NAS volumes for the NFS file systems.
I've bought this remote control that sais it works in Vista, XP etc. without any driver. Basically it has a bunch of buttons that replace the mouse and a bunch of others that replace basic keyboard functions (arrows, enter, escape). It has a USB IR receiver so I thought I could simply use it as a lirc remote in Ubuntu.
However, it sais absolutely nothing on it except for "PCremote" so during lirc installation I have no idea what to choose. And, interestingly, I accidentally discovered that it works in Ubuntu, too, out of the box. Controlling the mouse and acting like a keyboard. Is there a way I can forfeit current functionality and just get it to work as a customizable lirc remote? Or even better, keep current functionality but change it only for certain apps (xbmc, vlc etc)?
I'm a used Ubuntu user on a pc, and I like the french keyboard layout because it allows me to type accentued characters easily.I found a win-fr keyboard layout but it's much like windows and not so good.I found xmodmap.fr keyboard layout and I'd like to know if it was possible use it with my Mac SL 10.6.5, maybe I could do xmodmap xmodmap.fr or a way to convert to mac layout file.

I'm writing a script and I'm stuck. I need to read from keyboard to ask for confirmation while Im reading from a file. My code is this:
while read linea

I've got myself in a bit of a pickle.I've got 1 hard disk drive and was trying to load a second external drive.I tried to mount the 2nd (external) drive by editing /boot/ grub/ device.map but I must have made an error, because now it boots directly into sda1 openSUSE 11.1 and when I try to look at SDA2/SDA3 it say's Invalid System Type. Presumably because they're formatted with Ext4. So I can't edit back my device.map file.What I want to do is boot into SDA3 OpenSUSE 11.3. Would anybody know why it's only booting to SDA1 and/or have any suggestions to get me back booting to SDA3? This may be a 2 step process, because I may have to boot to SDA2 first so I can edit back my /boot/grub/device.map on SDA3 before finally booting to SDA3.

I stopped dd and found I had only 200 MB left of 200 GB free space (originally having over 220 free). I deleted the 1/2 finished backups but cannot find the data which was written to the drive. It is hard to think that that much data could be written with my slow pc in under one minute.here are the commands I performed if that helps locate the data:
dd if=/dev/cdrom of=/mnt/disk/home/mark/pccheck.iso

View 17 Replies View RelatedIn windows when I install gvim/vim, it automatically installs a context menu in explorer that lets me edit a file in gvim by simply right clicking and pressing v. For someone who edits a lot of files and is really used to vim, it is super-convenient. I want to do the same thing in nautilus. So I installed nautilus-actions and added to the context menu of editing with gvim. That wasn't hard. The hard part is getting that keyboard key to bind to that context menu item. Currently when I right click and press v, it sends the item to trash. I want it such that when I right click a file and press v, it edits the file in gvim. How can I do that? I want a good solution, and am willing to switch file managers/window managers if need be. This particular shortcut key is very important to my user experience.

.....and so on with different items. My goal in doing this was to enable the zoom button on the keyboard.
I do a bit of script writing, and part of this involves reading the text aloud and reacting to audio cues. What I'd love to do is set up a method of playing audio files at whim based on a general shortcut. So, say if I pressed <Super>C1, I could play ~/Music/cue1.mp3, <Super>C2 would be ~/Music/cue2.ogg etc.
Currently the closest I've got is using the terminal and a modified .bashrc to play via VLC's ncurses.
Code:
alias cue1="vlc -I ncurses ./Music/cue1.mp3"
Obviously this isn't very near to what I want. Entering a Keyboard Shortcut using the usual methods (xbindkeys, gconf-editor, the KeyShort Preferences GUI) to run
Code:
vlc -I ncurses ./Music/cue1.mp
doesn't play anything. Is it possible to launch these kinds of commands as shortcuts, or am I hoping for too much? My Google trawls have been pretty fruitless. I'm running Lucid, btw.
I just installed Debian 5.0.4 successfully. I want to use the PC as a File Server with two Drives configured as a RAID 1 device. Everything with the RAID device works fine, the only question I have belogs to the GRUB 0.97 Booloader. I would like to be able to boot my Server even if one of the disks fail or the filesystem containing the OS becomes corrupt, so I configured only the data partitions to be a RAID 1 device, so on the second disk should be a copy of the last stable installation, similar to this guide:[URL]...

How do I go about mounting a device if I don't know the file system type (e.g ext3, NTFS)?
