General :: Command Line - How To View More Of My History In Screen
Jun 28, 2011
I was running scripts overnight from the command line (inside Screen on a Linux EC2 instance) and some errors that I was not tracking occurred. I want to "scroll up" or view more of the history in Screen, but I cannot seem to find any commands that will work. I need to see the onscreen output "further up" than I can on my current screen. CTRL + a is supposed to put me into scroll mode inside Screen, but it's not working.

Can anybody show me how to view command history of another user? I am an admin on my machine. I can see normal history by viewing /home/user_name/.bash_history but i can't see commands of that "user_name" when they were doing sudo. Is there a way to view all command executed by one user?

I'd like show a certain line or lines of a file with context, kind of like a unified diff, on the command line in Linux:
$ (something) -l 154 stuff.py
150: def foo(bar):
151: """
[code]....

I am learning about group and user management with Fedora and can change the user's group using the usermod command but did not know if there was a command to see the group currently associated with the user.

I use vncviewer command line to remote access my pc from my notebook.
Is there any option to resize the view like windows client can by percentage?
my notebook screen size is 1280x800, while I use bigger resolution for my pc 1280x1024 if not mistaken.
already look here: http://linux.die.net/man/1/vncviewer but I don't see any option to do that.

I am having an install problem where the distro I am installing, installed at the wrong screen resolution. The display settings menu doesn't offer the correct resolution so I'm using half my screen real estate.

Bash's command history is great, especially it is useful when adding the history -a command to the COMMAND_PROMPT.However, I'm wondering if there is a way to log the commands to a file as soon as the Return key is pressed, e.g. before starting the command and not on completion of the command (using the COMMAND_PROMPT option would save the command once the prompt is there again).
I read about auditing programs like snoopy and session recorder like script but I thought they're already too complex for the simple question I have. I guess that deactivating that script logs all the output of the command would lead already in the right direction but isn't there a quicker way to solve that probelm?

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.

What are all the ways you could think of that someone could view your browsing history, upstream from your machine? They don't have physical access, there's nothing on the computer itself and the person trying to hack has skill so I'm thinking like monitoring a proxy somehow, using the ip address somehow, compromising the modem in some way, possibly having access to google account etc. I am new to ubuntu and have really dug it so far but I want to figure how this is/was being done

I have an installation of Maverick using command line only. It switches the monitor to standby after only about 5 minutes. Previous Ubuntu server and command line only versions do this too. Does anybody know where the setting is to change or disable this behavior? Perhaps something to do with ACPI?

I have used the below command to do that successfully for the previous version of ububunt, but this time I failed to do that with Ubuntu 9.10. I know I can do that manually by "sudo /etc/init.d/gdm stop" command. I try to change the name of /etc/init.d/gdm files, but the problem still exist.m"sudo update-rc.d -f gdm remove"

I am trying to make a java application run on a barebone computer connected to a tv screen trough hdmi. I want to make this run as light as possible so gnome probably is overkill. currently I'm running fluxbox but I would like to encapsulate video and some other gui stuff in the program and run it command line(trough startup script.) Another way to do this would be running it when fluxbox starts in full screen. But I really don't know how to do this or where to edit the startup script so I can run it. I'm using ubuntu 10.04 server edition and only installed jre, fluxbox, and of course ssh-server.
