I use the 10.04 ubuntu, somehow I did something and now the apt-get install command doesn't work. No matter what package I try to download, there's always a "couldn't download all packages run update or --fix...." message. When I scroll up I see that it downloaded some packages but it couldn't find them all. So I thought that I should try a different server. I googled it and found that the server's address is stored in /etc/apt/sources.list. I edited that file and replaced all the deb and deb-src lines with the server's address. I saved that but when I tried to download something (like vlc) I got a "E: Couldn't find package vlc" message. I also tried many different server's but there was no difference. Am I doing it wrong? Should I run a command after editing the /etc/apt/sources. list file? Or didn't I edited the file right?
I accidentally removed gnome-desktop when I removed PuleAudio. When I boot, I log in and I am stuck at the CLI. However, I can't get any command to install Gnome to work, including sudo apt-get install gnome-desktop or sudo apt-get install gnome. I forget what the error messages were.
I am trying to install openoffice, so I downloaded installation file from openoffice.org and saved in my desktop... /Desktop/OOo_3.2.1_Linux_x86_install-rpm-wJRE_en-US.tar.gz Now I tried using yum command it doesn't work also sh <path> its not working...
I don't know why --exclude doesn't work when I use tar command. Please see this code Code: mahmood@pc:~$ l a/ 1.txt 2.txt 3.txt b/ mahmood@pc:~$ tar cvjf compressed.tar.bz2 --exclude=/home/mahmood/a/b/ a/ a/ a/2.txt a/1.txt a/3.txt a/b/ mahmood@pc:~$ As you can see although I excluded b/ but tar command ignored that.
I'm running this command, and seems not to work, following the command:Quote:for nic in `ls /sys/class/net | grep -v lo`; do echo ${nic}; udevinfo -a -p /class/net/{nic} | grep -i address; doneThe output is the following:Quote:eth0eth1But the output should show something like this: (showing the MAC address)uote:
I am have trouble getting the ls command to work exactly how I want, for example, sometimes I want to list the contents of a directory into a text file by command:
Code: ls directory > list.txt
(assume the only objects the directory contains are files with extension .dat eg file1.dat, file2.dat, ...)sometimes I want the relative path of the files prepended to them in my text file eg:
path/file1.dat path/file2.dat path/file3.dat
[Code].....
It feels like ls is unpredictable in this regard - sometimes it prepends the path and sometimes it doesn't and sometimes it adds both entries (with and without the path prepended into the text file)....How can better control the way ls works?
I am teaching using an Ubuntu 10 server. The course stipulates the students use the mail command to send me assessment work, however I can't get mail to work (I did have to install it in the first place). After I end the message with a dot I get the message "send-mail: cannot open mail:25".
i am using rhel 5.4..today i type the command setup! is not workERRor: error while loading shared libraries: libslang.so.2: cannot open shared object file: No such file or directory
I want to install some software using sudo apt-get command,but it dosen't work.(my network works well) how to handle it? below is the output of terminal:

Ive been using linux for a few months now and every now and again i come accross a program that doesnt have a rpm package but says that it can be installed on Fedora using source. I'm familiar with build essentials and the following commands:-
tar xzvf package.tar.gz cd package ./configure make make install
but from what i have read fedora uses a differnet compiler. I'm trying to install Buddi budget manager and the ./configure command doesnt work, which im guessing is because it doesnt have a configure file? Can anyone confirm how to compile from source and whether there are any tutorials specific to fedora.
When in command mode one can come out of the file temporarily by Code: :sh in command mode. When I find myself on the shell on RH 9 the aliases dont work but in RHEL 4 all aliases work like charm. Does anyone know why is it so?
I can make aliases fine by editing the .bashrc file in my home directory, but the first thing I do when I open a terminal window is sudo su so I don't have to type sudo in front of every command. The problem is, I am then not able to use my aliases. How can I make aliases that work after I run the sudo su command?
I have a PDF that I built using BIRT, and that works fine. At this point I'm trying to print it using lpr or some other command. It seems as though I should just be able to type lpr invoice.pdf and it should print to the default printer. However, lpstat -t shows "Empty print file!" for the printer, and the printer doesn't do anything, let alone print the file. lpr -l invoice.pdf prints the file, but unformatted - just a bunch of characters and whitespace on a seemingly infinite number of pages.
When i use the shutdown-command in the terminal as root, it nearly works. It starts to shut down, and it looks like all programs and the kernels shuts down. I end up with a black screen, sometimes with the ubuntu-logo on, but it never powers off. I have to force it off by holding the power button. When i use the graphical interface to shut it down, it works perfectly. The poweroff-command works without problem too.
CUPS was not originally installed on my server, I have installed it but cannot print to my network printer. On my laptop, I can... they are both running the same version of Debian. What could be missing?
Here are some details...
I have two computers running the same version of Debian. One is a server with no GUI and the other is my laptop with GDM installed. My laptop (which prints with no problem) is connected via Wifi. My server is connected directly to the router via Ethernet. I cannot print from the server.
The printer is a Canon Pixma MP495 that connects to the router via Wifi. I have downloaded drivers for the printer from [url] and installed them successfully using dpkg on both computers.
Right now I have a regular text file that I am using for a test page. To print from my laptop (with success) I type:
Code:
This does not work from the server. What could I be missing?
" Mark the start of the text with "v", "V" or CTRL-V. The character under the cursor will be used as the start.""With CTRL-V (blockwise Visual mode) the highlighted text will be a rectanglebetween start position and the cursor."I can mark the start with "v" or "V".But it doesn't work when I push ctrl+V.
Im running opensuse 11.2 with "Lxde". Problem is I cant get xmms2 to work from the command line. I think i need to get mad (mp3) support to work. I installed libmad0 but when I check the installed plugins, theres nothing there to handle mp3's. Heres the installed plugins:
I am going to compile and install my first linux application from the command line. The program is the port scanner program NMAP, and I am looking at the documentation to learn how to do it. I saw this thread [URL], and I just want to make sure I understand what it is I'm doing.
bzip2 -cd nmap-5.35DC1.tar.bz2 | tar xvf - cd nmap-5.35DC1 ./configure make su root make install
"bzip2 -cd nmap-5.35DC1.tar.bz2 | tar xvf -" Here I am calling the bzip2 program to work with a specified file. look for the file nmap-5.35DC1.tar.bz2 in the current diretory (-cd) and to pipe (redirect) something, this is where I get lost, I think. And I know what x & v mean but not f, or what that has to do with the previous commands.
cd nmap-5.35DC1 Chage to the named directory. ./configure I assume this is a command? make Builds an executable su root make install not sure what the difference is between this and the above.
I am looking out for a command which can give me the list of applications installed and the corresponding install paths for those.let me know if there is any such command. Also, i am using rpm command to get the list of packages installed(i am assuming that this shows the list of applications installed).
"You'll probably want to operate from inside your home directory. If your user is (for example) username, your home directory will be /home/username/. For the rest of this section we will assume you have downloaded your zip file to /home/username/src. If you do not have a src directory, you can create it with the following "mkdir" (make directory) command:"
Where do the commands go? I cant make it work in terminal. How do I get back to "home" from where i am now? example /home/mydesktop/. I am working in mydesktop. I have downloaded some packages that pkcon search will not find, but when I try to install them using "synaptic" it cant find the packages i dl. So I found this tutorial.
"So, we have our source package in /home/username/src/. Change to the /home/username/src/ directory with the "cd" (change directory) command like so: cd /home/username/src/ but I dont know where to write the commands.
