General :: Bring Cursor To 1st Char In Current Line (Command Mode)
Dec 4, 2010
Just in case someone can reply a silly question, I've quite forgot the vi/vim command to bring the cursor to the 1st char in the current line. I do remember that for bringing it to EOL is '$'.

so the safest way to go about this is to assume I know nothing. I mean, I have a rough Idea of what a kernel is, no idea what a shell is, etc. I do consider myself computer savvy, but know NOTHING about linux and thats why I'm Diving in, hopefully not too much, this is just to give you an idea of what we're working with here.
After several install attempts I kept getting a blank screen. Whether it be black,white, or the default gnome desktop (without any icons, and simple things like ctrl+alt+backspace just doesn't work, or anything else for that matter) I was ending up with a blank screen. Driver for moniter....maybe....but I did succesfully install it once, and it worked like a charm...shutdown properly, and the next day after work...Boom, same thing after startup.today I started from scratch and re-installed....samething, until I hit the power button, went from the dvd(iso) and did a fail safe, now my resolution is much better than it was the first time..Actual questions.....what did I do to fix it when failsafe never worked before?
Is there a way to save these settings, so I don't run into the problem again, because I don't even want to turn of my computer at this point?If i'm trying to dive in and learn the command line actions, is there any substancial difference between gnome terminal or hitting "c" to bring up the command line?

Let's say I have a program open on another virtual desktop. Is there a way I can bring that program to the current desktop through a script? The following command is the closest I can get:
wmctrl -a program This will switch to the desktop where the program is open and make it the foremost window. However, instead of going to the desktop where the program is, I want to bring the program to the current desktop. There is also this command:
wmctrl -R program The documentation says that this will do what I want, but it just does the same thing as the former command.

How do I install Broadcom Wi-Fi on Arch Linux in command line mode on an Acer eMachines EM350?
I assume that Broadcom STA should be the driver used and my USB key the way to install it with the help of another PC, assuming that I can't use a RJ45 ethernet connection on LAN.

Is there a vim command or sequence of commands that will append the current line into the clipboard? Given the example below:
4
5
3
1
2
Lets say I wanted to cut 3, 4, 5 (in that order) then paste them below 2 so that the numbers are in order?

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

EDIT: sudo /etc/init.d/gdm stop worked, not sure why it did not before. Sorry for the whining!
I need to boot Ubuntu into a non-x, command line mode. So I can install an nvidia driver for my new GeForce GTX 260 (I had a GeForce 7900 running on my Ubuntu system using the synaptic open source 185 driver for nvidia, but there is no driver except the one I downloaded just now from nvidia's site for the GTX 260 card). That requires there be no X session running, not even in a separate domain so to speak. There is no rescue mode in Grub2. Recover mode in Grub still boots an X session (Gnome). Alt+F1 appears to be a clean command line terminal but even that does not work because the nvidia driver installer script sees through that ruse and knows there is an active Gnome session. I tried sudo /etc/init.d/gdm stop and that did not work. I tried ctr+alt+backspace and that did nothing.
What can I do? I tell you some days linux is just too frustrating, about to just toss the baby with the bath water and go back to Winblows. Bought a new graphics card today, and here I am stuck not being able to even install the driver from a command line prompt, geesh.

I am using xterm and sometimes when typing long commands into a small window, the command extends beyond the end of the line. On my old uni setup, when this happens, the cursor moves to the line below and you can see what text you have typed above however on my slack 13 setup, it overwrites the current line so you cannot see what you have typed! How can I set xterm to move onto the next line instead of overtyping?

my fedora 14 did an automatic update tonight and on reboot it hangs displaying the "f" before the login in menu. The "f" is how I now feel.I do "fn+f2" as it is booting and it displays the sequence of loading items which report all is "ok" until it gets to "jexec services" and then it hangs.I do not know how to access the machine in command line mode and I am not sure what to do from here. I beleive the "jexec service" is a Sun Java item but I am not sure.

My guess is it starts: phatch -vkc --desktop [action] [path]

Is it possible to instruct Ubuntu to start up (GUI) Graphical User Interface mode from (CLI) Command Line Interface mode? In the old days, you can type "win" in DOS to get into Windows - something along that line. Is it possible for Ubuntu in this case?
Yes, you can reboot to switch between the modes, but shouldn't there be a command for this?

I just loaded up the Ubuntu 10.04 onto a newly scratch built computer. It went to the desktop after loading up and asking for my password. I then navigated to SYS>ADMIN>DRIVERS and preceded with download of recommended drivers for Nvadia G430 on-board display adapter. Restarted the computer to activate the new drivers and it's stuck in Command Line Mode. I tried Ctrl/Alt/F7 to escape, along with a bunch of other things but nothing will kick this puppy into the desktop.

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 need to execute evince from command line or from a shell script and open it directly in full screen, or start some program for presentation.
I mean:
$ evince (this opens evince)
$ evince /dir1/dir2/file.toview (this opens evince and the file.toview but not in full screen)
$ evince /dir1/dir2/file.toview 'in mode presentation'

First time I've done this in awhile Upgrading my Slackware64 -current VM, following the standard routine that has always worked in the past -
Code:
slackpkg clean-system
slackpkg install-new
The clean-system removed 2 packages -
util-linux-ng
eggdbus
Installpkg will no longer work, complaining that the rev command is not found. The problem hit with the removal of util-linux-ng. I cp'd util-linux to ~/. Extracted with tar and executed the doinstall. Fixed.

I am using Vi editor for editing and configuring my file.I am facing a little problem when there is long file like 3000 lines. Normally i use
Code:

Greetings, I have installed a VMware host on Windows 7 64bit and followed with a 10.04LTS 64 bit guest install. Everything went smooth. I have used VMware before, but the other way around.. Linux host and Windows guest.
So this time I am installing the VMWare tools on the guest, ubuntu 10.04, but it seems to be failing. The vmware tools install ran fine the first time with no errors, but I was getting the follwoing error after logging into the Ubuntu guest afterwards.
Could Not Apply the Start Configuration for Monitors
Error Line 1: Char 1 Whitespace or empty file
So I re installed the VMware tools once again, but still the same.
I am hoping that someone here has come across this before and hs a workaround. I don't think the vmware tools was installed correctly.

I mis-clicked and now my monitor resolution is WAY too high. I could fix that by re-clicking, but the menu to bring up the screen I need to click is off-screen.By blind clicking I got a command line window. Can anybody tell me the command line to bring up the system preference for monitor resolution?
