Ubuntu :: Recommended Newbie Guide For Command Line?
Jul 20, 2010
I just installed Ubuntu 10.04 Server the other day, which gives me access to a command line only, to start out with. I'm hoping someone would be able to recommend a guide (online or a book, either way) for absolutely clueless beginners, so that I can learn to competently get around from the command line.
This would include information like:
Navigating the file system.
Editing text document.
Installing drivers.
Mounting data sources.
Installing and configuring packages.
and eventually installing a desktop environment.

I have been trying to set up an LDAP server for a development environment as part of an internship for a week now, and I cannot get past this point. I have been following the 10.04 server guide to set up LDAP here: URL...Once I get to the following point in the guide, it just hangs:"As an example of modifying the cn=config tree, add another attribute to the index list using ldapmodify:"I've been working on this for a week and can't understand why this won't work. I am fairly certain that I've followed the guide to a 'T.'Any idea why am I receiving a permission denied error? Is this a permissions issue with one of the config files?

I know my way around MS Windows much better, but I just don't feel right trying to program something for Android on a Microsoft operating system. I am interested in Android programming so I followed the instructions on [URL] to install the environment on my computer...
I just installed the JDK, SDK, Eclipse successfully (or I assume):
* When I get to Step 4 where I'm supposed to run 'android' it will not run. I get the error message "android: command not found" (I am definitely in the right directory).
** When I double-click it in nautilus, it opens up in gedit. I can set the permissions in nautilus (through the properties - Allow executing file as a program) and get it to work,
My system:
Intel i7
Ubuntu 10.10 Maverick Meerkat
android-sdk-linux-x86
eclipse 3.6.2

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.

Code: cmd='date | wc'
$cmd If this script is executed, an error is generated. The reason written was that "The execution fails because the pipe is not expanded and is passed to date as an argument".What is meant by expansion of pipe. When we execute date | wc on the command line, it goes fine.then | is not treated as an argument. Why?

I tried
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'm about to install a 'new' ATI Radeon video card into a Ubuntu 10.04 computer of mine (an ASUS A7VT) that has VIA onboard graphics. My question is, how will Ubuntu deal with this? Will it automatically download the required drivers or would I be better off with a fresh install after I've put the card in?

How can we do everything, or as much as we can do, from the command line? In particular, I am trying to get rid of the top panel in Ubuntu. Because,
1) It takes unnecessary valuable space.
2) Even if I use a huge monitor, it introduces distraction to me while working.
I created a shortcut so that with a single keyboard key I can open a terminal. For example, if I want to restart the computer, I use: "sudo shutdown -r now". Or I can even create a shorter alias. So I do not need the logout menu. But my problem is, some programs put an icon on the top panel when they are working. So, what is the best way of using command line, and getting rid of the top menu.

I was wondring if 7zip still only runs in the command line. I searched and got a bunch of old threads like this: [URL].. but I'm not sure if that has changed since 2007. A GUI would be awesome.

I have a virtual private server that I SSH into. While I am using SSH, I need to be able to FTP from command line to another server. I want to do this in the easiest most sure way possible. (I am not using my real IP below for security.) I have tried the following commands.
sftp 10.99.99.99
ssh: connect to host 10.99.99.99 port 22: No route to host
Couldn't read packet: Connection reset by peer
ssh 10.99.99.99

About two months ago I upgraded my dual boot Linux-x86-64 Vista from Heron to 10.04 Lucid. Initially everything worked fine including wireless etc. Once I accidentally changed a few /etc permissions which caused a problem, but fixed it going into recovery mode. For the past weeks, I only used the windows. Over the weekend I tried logging into Ubuntu, the gnome would not come up. So, I went into recovery mode and typed "sudo apt-get update && sudo apt-get upgrade" which also went through. However, after that I lost the recovery options. I had used that command very successfully in the past. Right now, I have no command line that would allow me to type something. I was wondering if there are any keys Alt+Del + something that would give me a prompt I can work with. I'm totally baffled as to how this can happen.

I have tried few things which were I found out on other forums but nothing seems to be working. how can I log in to GUI rather than command line.

I'm new to Linux and Ubuntu 9.10. I have installed Ubuntu 9.10 on an older Compaq Presario 6100. Initially my built in wireless was not working. I searched the forum and was able to get my wireless working (I think) by installing the BCM43XX driver. I assume that works on my computer since I believe the BCM4306 driver is needed. Anyway, assuming my wireless is working, my home network does not show up in the pick list when I go to network<wireless.
I've spent a couple of hours already researching this and up someone can help me out. I would really like to give this new system a try.

every now and then my company cleans its it trash by giving away computers to its employees. this i became the owner of a p4, 2ghz compaq evo with 512 mb ram and no hard drive. i bought a 500 gb hdd, dowloaded ubuntu, created a live disk and in a matter of minutes i had a new desktop! i love it! a new computer with a new operating system set by a non-techie in 15 minutes? not even microsoft can beat that. oh, and the total cost was zero!
then i started clearing issues (mysterious crash on p4 computers solved with a patch, screen resolution solved with a new mode, not recognized microsoft webcam to be solved, connection to stora nsa to be solved, etc.). this is nothing different from what you would go through installing windows on a new computer, in fact the process seemed easier for me as there's tons of documentation and people willing 1. overall system performance, mostly while browsing seems low. could it be the 512 mb of memory? would it improve its performance to jump to 1 or 2 gb? or it's just the processor that's too slow and not all the memory in the world would make it faster? while we're at it, is it reasonable to expect good performance on ubuntu 10.4 on a p4 2.0 ghz? (my notebook, a 2 ghz core duo runs faster on xp, but it has 3 gb memory, so i guess memory would help...).
2. choppy videos and other video, both in partial and full screen modes. again, would more ram help? updating drivers? updating flash? (i think it's all updated, but i'll retry...). or is my bottleneck in the processor? 3. my computer has an extra video card, but it's disconnected. i'm not sure about brand or model or even whether this would be an improvement on the on-board card. should i plug it and see what happens? would a better video card improve my performance?
simplifying, this is a computer for me to play and for my baby boy to pound at the keyboard. if i were to spend little money on it, what's the best investment, memory or a new video board? (i think i know the answer, memory). i don't want to extrapolate too much from my windows experience because this is a new os, but i think i would go for extra memory. if memory were the solution to all my problems... how much memory? should i go for an additional gb? full 2 gb? 3? what about buying a 1 gb card and plugging it side by side with the existing 512 mb? would 1.5 gb be enough?

So I installed FC11 and it seemed to be working ok I was having an issue configuring sendmail so I decided to use Yum to remove it and to re-install sendmail.I type yum remove sendmail and it asked me if I wanted to remove 39 dependancies.

Lately I have been very interested in minimal Linux distro's. At the moment I am specifically searching for command line only intended distro's (up to date) and even more preferable: command line only distro's available on a live cd or usb. Can anyone of you point me in a right direction or recommend a distro?
