Code:
chown -R owner:group *
which does not work on the invisible directories (why?). When I used ".*" as wildcard it changed all (visible) files including the parent directory (the one I was currently working in which is the "dot") . I can change the invisible directories owner and group using dophin but how is it done from the command line?
I noticed in phpmyadmin that we can export a database in type update. Indeed we have update... in place of insert.... is there anyone know if it possible by a command line or by a simple PHP code ?

In dealing with the Nvidia Powermizer, I have to set it to "Prefer Maximum Power" mode from adaptive mode in order that I can avoid laggy in using my GUI. However, it doesn't save this setting so I have to manually tweak it everytime........
Someone on the web taught me to use the following command line:
nvidia-settings -a [gpu:0]/GPUPowerMizerMode=1
running it in the terminal it will set to the mode I want.
Would I be able to make my computer run the above command in terminal everytime it starts? I tried to put the command in the start up applications and it seems not working.
I have a bunch of mislabeled files among other things but I'll start with this first. as using the command line to fix this issue.

View 11 Replies View RelatedI'm trying to set up an unprivileged user on some field systems running 11.04 with the standard Gnome shell (rather than Unity), and ideally that user would not have access to the command line. The user can log in through GDM (but not the text consoles) with no password, so I need to provide the absolute minimum of privileges; basically the user should only be able to run one program.
I've already set the /desktop/gnome/lockdown/disable_command_line key with gconf-editor for that user, which successfully disabled the "Run Command" dialog. Unfortunately, even though the description of the key in gconf-editor says "prevents the user from accessing the terminal...", the terminal emulator is still accessible from the Applications menu, and I haven't been able to find a good way of disabling the terminal or removing it from the menu. The only thing that occurs to me is an ugly hack: replace the gnome-terminal binary with another that checks to make sure the user is not the unprivileged one and then starts gnome-terminal.
The ability to manually boot using the Grub command-line constitutes a big security risk in Linux, IMO.Any OS can be booted in this manner from a PXE-LAN, USB, or CD/DVD drive, circumventing BIOS-imposed boot restrictions. (Once a foreign OS is booted, of course, it can be used to access any part of an unencrypted hard drive.) Placing passwords or locking menu items (in the Grub configuration files) does not prevent a user from booting manually using commands entered at the grub command-line.
As it stands now, when presented with the Grub menu (or after bringing up a hidden Grub menu with the "ESC" key), a user only needs to hit "c" to enter the Grub command-line mode to facilitate any type of bootup whatsoever. (They can then enter manually the Grub commands to boot an OS on any device.) This is extremely insecure and allows any passerby to boot the computer with a few keystrokes and a bootable USB drive. How do I configure Grub so that it will require a password in order to enter the command-line mode (and thereby restrict boot options to the menu, which can then be password protected/locked) ?
The GUI for network configuration of Fedora is marvellous such that the configuration is almost fool-proof. But how can I make the connection by hand in the command line mode? It goes okay except the very last step. When I disconnect the eth0 interface from the right-hand side of the desktop GUI, I tested how to bring it back by command line but I failed. When disconnected, the ifconfig still shows the eth0 interface, with just the ip address portion changed.
I tried "ifconfig eth0 192.168.1.xx" to give it an ip address but the connection is still down even if the ifconfig shows an ip address for the eth0 interface. Then I tried "/etc/init.d/network restart" and "ifup eth0" and also "route add defaut gw 192.168.1.1" but none of these could accomplish the same work as a single click on the GUI to connect. I am very curious about how to do it in the terminal.
I've got an install of CentOS 5.3 in a VM which was installed without X or Gnome.I've added X (yum groupinstall 'X Window System') and Gnome (yum groupinstall 'GNOME Desktop Environment) and can now run startx no problem.However on boot I get a command line login rather than the graphical login screen one normally gets if Gnome is included at install time.What do I need to do to get the graphical login after boot?

I use a program which makes a large image which I have to scroll to view. The program has no way to save the image, and I have no access to the source to modify it. The only way I have to get the image from the program is by screenshot. My goal is to save the full size image without having to piece together individual screenshots. I'm using this script to try taking a screenshot:
#!/bin/bash
window=$(wmctrl -l | grep "Program$" | awk '{print $1}')
wmctrl -v -i -r $window -e '0,0,0,6030,5828'
wmctrl -i -a $window
import -window $window ~/Desktop/screenshot.png
This uses wmctrl to get the window id ($window) for a window named "Program". It then tries to resize the window to the desired dimensions. It uses imagemagick (import) to save a screenshot.png on the user's Desktop. All of this works except the resize step. I can resize the window using wmctrl -r -e, but sizes greater than the screen size don't work. I'm using Ubuntu 10.04 and the Gnome Desktop. I run two monitors, but I've tried this with one of them disabled. Is there a way to resize the window larger than my screen to get a huge screenshot?
Part II: I tried using xrandr to set up screen panning, so as to have a bigger desktop than my monitor. xrandr --output LVDS --panning 2600x2500 This command makes the laptop screen pan over a 2600x2500 size desktop, even though it can only show 1440x900 at one time. To turn off the panning, I can use a similar command to set total size and with zeroes for the panning section. This gives me back my original laptop display behavior. xrandr --fb 1440x900 --output LVDS --panning 0x0 This is all done with xrandr, and does not require any Xorg.conf changes (my Ubuntu system doesn't even have an Xorg.conf).
My video card seems to only allow about 6.5 million pixels, even though the maximum dimensions are 8192x8192. That maximum seems to be the maximum for either dimension, but there is a limit to how many pixels can be drawn, which is the width multiplied by the height. Once I did the screen resize, I tried my script again and got a screenshot. The screenshot however is totally scrambled. I'm not sure if it's unable to take a screenshot of an off-screen window or if it is unable to handle the large dimensions of the window. With the panning display, the window should think it is visible, and the window manager should think it is on-screen. So there is a pixel buffer somewhere with those pixels in it, so there should be a way to get a screenshot.

View 5 Replies View RelatedI want to make my computer invisible or hidden to the other computers connected to the same wireless network. In other words, I want to turn off network visibility or network mapping. I think this amounts to the ability to turn on and off the Windows Link-Layer Topology Discovery (LLTD) Responder. [URL]... On windows, I believe this would be comparable to setting the wireless network as Public instead of Home. I like to share files using Ubuntu when I am connected to my Home router, but I don't want to be discoverable or visible to clients on a public wifi network.
I have already created a shared folder on my desktop which installed some sort of networking components to interact with Windows, but I don't want the public wifi network to see this folder, or my computer name at all. I want to be invisible to other clients on the same network. Right now I am visible and can see other clients connected to this public wifi router.
(In case some ask: I do not want to disable SSID broadcasting on the router as it is a public wifi router that I do not have access to.) Can anyone explain how to do this (preferably with a GUI method so I can reverse the steps when I connect to my Home network)?
I've got a NAS running and I'd like to somehow make some of the folders and files invisible to certain users only. For example, if I 'ls' a directory, I want to see files 'a', 'b', and 'c'. But if another user does 'ls' in the same directory, I only want them to be able to see 'a' listed.I know I can use 'chmod +700' to make certain files not able to be read/written, but the filename would still appear in a 'ls'.I know I can put certain files inside of a '.hidden' file in the folder, but then it would be hiEdit : I'd also like to mention that the users that connect to the NAS could be coming from Windows or Mac operating systems. So hopefully the solution would work for users from those systems also..

how to pass something more than a one-command startup for gnome-terminal. I will give an example of what I'm trying to do here:
Code:
#! /bin/bash
#
#TODO write this for gnome and xterm
[code]....
This same error occurs if the gnome-terminal line is changed to
Code:
gnome-terminal -e mcTerm
Is there any way to pass more than one command on to gnome-terminal? I have tried various single and double quoting senarios and in a final attempt, I abstracted to an exported function all to no avail. Perhaps even though gnome-term is better at many things than xterm, xterm trumps it in this instance.
