How can I do to make less not to do line wraparound? That is, if there is a line exceeding 80 chars, I want to see only the first 80 ones. Of course, if I wish, I would afterwards be able to see the rest of the line by pressing the End key.

[code]...
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.
How, using the command line can I detect my wireless card and make it work under SUSE Enterprise Desktop? The wireless card works in Win XP.

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.
To hide the user input to be displayed on screen, use the terminal line setting command stty -echo, whatever the user enters after this command will not be displayed in the screen. to make the input characters get displayed on the screen use stty echo.
View 1 Replies View RelatedI need a substitution of a particular string (StringA) with another string (StringB). However, there may be more than one occurrence of StringA within the file, but only one instance needs to be changed, which is why I'm trying to be sure of it's positioning against something I know will be unique in the file, and will always have the same distance from the string to be replaced. So, I intend to match on a string (StringC) above the string to be substituted and then have sed go to StringA below and replace with StringB.

I am combining data from a couple different input files and creating an output file in a specific format. I notice that if I use the >> operator, information gets appended to a new line in my output file. This is useful, but if I'd like to append onto the CURRENT line, is there an easy way to do this? I've been googling around and see lots of complicated answers, nothing that suggests to me an easy way to do this. For example, if my output file looks like this:
b1a:] cat test
hello my name is
b1a:]
and I'd simply like to append "Bob", how can I do it? If I use
b1a:] echo Bob >> test
b1a:] cat test
b1a:] hello my name is
Bob
b1a:]
So what I would prefer is some command that would create the result:
hello my name is Bob

I am trying to figure something out as part of something else I am going to do. I was just wondering the easiest and quickest way to run a loop at the Linux command line which will make x amount of symbolic links when I need them.

I have a slight problem. Whenever I type something in rxvt, and sometimes it's a loooong something, I end up having to make it span multiple lines, as do you, probably. Anyway, my problem is that if I'm in any console at all, (aside from the TTY console and such) and I try to go multiple lines, this is what happens:
Code:
[root@SectionI13] > aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
After the first pass...
Code:
aaaaaaaectionI13] > aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
And after the second pass...
Code:
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
aaaaaaaaaaaaaaaaaaaaa
Now, I'd be fine and dandy with this, if it wasn't so hard to figure out what I was typing after the first pass, because it's just plain hard to understand a command when there's the second half of it in front of the first half of it.

View 14 Replies View RelatedThe 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.
