Software :: Determine Difference Between Application List And Default One In Ubuntu?
Nov 4, 2009
I have used ubuntu for some time, installed&removed many packages, and now i need to determine which packages are removed&installed on my installation, comparing this list to default one. If i had another machine with just installed ubuntu, it would be just as easy as list installed packages on two machines and then diff these lists. But i don't have another machine to clean install ubuntu on it. How can i do this without having clean ubuntu installation?
I have created a custom debian netinst USB stick. It has the default UK repositories in the sources list, but people in the US also need to use the stick from time-to-time.
Would it be a bad idea to mix US and UK repositories in the sources.list? Would Debian be clever enough to pick up the best repo depending on where the user is using the OS from? Or would I need to be a bit clever and create some sort of script to deal with this. (I am avoiding non-free/experimental software).
Finding the process that is using a certain port in linux
I have an Ubuntu Server setup, where I'm trying to set up a daemon that wants to have access to port 8080. When I run the command, the error message says it's being used by another process. But which one, it doesn't say. How can I go about finding which program uses this port?
I want to generate a temporary random list from a directory of files and then determine the size of an arbitrary block of files from this list (say 1-25 or 26-50) and add their names to a file along with some other info for each name. I can generate a random list with file sizes like this: ls -l | sort -R | cut -d " " -f 6 but i'm not sure how to add up the sizes of just a certain block of these files and at the same time save the file names.
I just upgraded my kernel to version 2.6.38 & I seem to have missed a few modules. I tried using diff to get a list of the differences between the files lsmod-2.6.35 & lsmod-2.5.38, which I created for this. Unfortunatly I can't seem to figure out the right syntax to do what I want which is to just show me whats missing. For example, I want to subtract the lines from file1 & file2 which are the same, leaving me with the difference in file3. i.e. file3 = file1 - file2 Is this possible or am I just using the wrong program.
Is there a description of the features and differences between the Desktop and Default kernels? Did "Desktop" arrive with 11.2 and 2.6.31? I did not notice it at first. I loaded 11.2 on a desktop machine and both default and desktop kernels were loaded to system, with Desktop set as default in grub. I have been working thru several "strange" behaviors ever since loading 11.2. At the top of my list has been the ability to shutdown the system from remote logins. I normally connect to the system via a Xwindows package (Xmanager). X works fine and I could shutdown via the GUI (Application Launcher - Leave-Shutdown).
When connected via a remote ssh link, either from a windows machine or a different linux machine, attempts to shutdown (shutdown -H now) send the expected messages, close the remote connections but leave the system still powered on but in a no-remote-connectivity state. When I upgraded to KDE 4.3.4 following the Forum Repository guidelines, I could no longer shutdown via the GUI. In searching about, I found that the Desktop kernel was running. Changed grub, rebooted under default, shutdown under GUI works again. So, for starters, I am trying to decide which kernel environment (default or desktop) should be my target for continuing to work thru issues.
I'm looking for a to-do list program that can be shared between my windows 7 and ubuntu dual boot partitions. I already thought of google calender but I need offline access as well.
I recently got a new desktop, and did a fresh install of Ubuntu 9.04 Jaunty Jackalope. The reason I installed 9.04 is because the laptop I have been on for the last 7 years or so suddenly stopped operating with grub updates. I would t urn the computer on and it would never get past the 'grub loading' screen. but thats a whole different story. So I did a fresh install of 9.04 off of a startup disc I made a while back. Then I copied my /home file from my laptop (the old one) and inserted it into the new desktop's /home directory. Worked like a charm (more or less), and all my settings were transferred to my new computer. Desktop, Preferences, Admin stuff, I can't find a problem with it. Now for the applications.
I've tried multiple how-to's but none of them have worked. I found one that told me to do the following in terminal. Keep in mind, although I've been running Ubuntu for about three or four years now, I would still consider myself a noob. Anyway:
sudo dpkg --get-packages <filename><destination>
this left me with a text only file called 'package.selections' I was then to copy this file into the home folder on the new computer and run the following:
sudo dpkg --set-selections <directory>
Up until that last command, everything worked just fine. The list had tons of package titles (none with a .deb or anything though) and their state, got it on to the new computer and ran the code only to get the following error:
dpkg --set-selections does not take any argument
So i ran it without the directory, and it gave me a new line. So I typed in the directory and it gave me the following:
dpkg: unexpected end in package name at line 1
I've tried numerous other commands changing up the syntax as I go, but haven't gotten any farther. My goal is to have all the same applications installed on my new rig without having to go and install all the packages one by one.
A friend installed QCad. All seemed well but he cannot find the app in the Applications menu under any category. Strange thing is, the Software Centre shows that it is installed. How can he run it if it does not appear in the Apps menu?n it be run from the command line?
Since I do not have an internet connection I would like to get the DVD. I would like to get a list of the application contained on the DVD. Can someone direct me to a fedora link with that info.
Any of you ever heard of OS/2 WARP? My dad is a longtime user, as was I until I got my Mac (and now my netbook with Ubuntu). In any case, the OS is a tad...obsolete and my dad at some point wishes to try Ubuntu. In his current setup, he has a "Window List" that can be activated using a keyboard shortcut. It's a popup (not in a menu bar or "panel") that can be moved around and resized. From that you can use your keyboard to navigate to the program or window that you want. For instance, if I want to get to Firefox, I press Ctrl+Escape (to activate the Window List) and then I hit "F" as many times as needed to highlight "Firefox". Then I just hit "Enter" and I'm there. Anything similar out there for Ubuntu (it is preferable if the solution has text as well as icons or else can have the icons removed leaving only the text)
In addition, both him and I would be interested in some program for launching/switching to programs using keyboard shortcuts. On the Mac, I use Quicksilver for this, where it actually Launches the program if it's not open, and switches to it if it is. However, Gnome Do unfortunately lacks this functionality and I have no way to do it off the top of my head.
Is it possible to suggest an application to appear in the "Featured Applications" list in the Ubuntu Software Center?I would like to suggest that "OpenShot Video Editor" is included.
I open a new thread for ask you some help about a graphical problem concerning my graphic card under gnome3. My laptop is an Acer Aspire 5738zg and my graphic card is an ATI mobility radeon Hd 4570. I'm under gnome 3 and just made a recent installation in 64 bits from the DVD . I'm running with the free driver.I just got an horizontal artifact in the application list , here comes the screenshot URL...
I tried to find some help in french forum , but nobody have any ideas and the problem is reported on a bugzilla but those days , there was no answer or following on this subject. I give you the link too URL...I did a glxgears too and i can say you i'm running at 60fps so everything seems okay with the vertical synchro.
I once plugged in my mini video camera (6, good buy), and I accidentally clicked on 'Always use F-spot to open this kind of device'. The problem is, I can't set it back to nautilus. I've looked everywhere, including right clicking on the drive in 'Computer', but the default application in the 'properties' window is set to 'open folder'. When I right-click on the drive, I still see F-spot on the list. If I select 'Open with other application', I can't change it from F-spot.
I do a lot of torrenting on my xubuntu box, and ever since my introduction to computers, I have become attracted to the command-line way of doing things. My default editor is vi, my default torrent programme is rtorrent, my default gopher client is lynx... you get the idea. My web browsing, and sometimes also my file browsing, however, is always in graphical mode.
As you know, downloading a torrent involves downloading a small file with the extension .torrent. When I clicked on this .torrent file, although I have rtorrent installed, Transmission showed up. Not to insult the Transmission guys, but compared to an ncurses-based torrent client, Transmission is just too bloated. Anyhow, I right-clicked on the file, Open With Other Application, etc.
Into the box that showed up, I typed /usr/bin/rtorrent (the path to my favourite torrent client), and clicked OK. I double-clicked on the torrent file again, and nothing. Transmission didn't show up, but neither did my terminal client. I'm sick of having to go to the Applications menu and firing up the Terminal to torrent a file. I'd like to have the Terminal open up with rtorrent as soon as I double click the file.
just click the [Computer] button at the left-bottom corner of the GNome desktop, the menu will shown, now press the printscreen button [PrtSc], nothing happen. no screenshot was made.or open any application , then click the menu like [file], let the menu list shown, then press [PrtSc] button, same thing, nothing happen.
I like view file listings in Nautilus in the List View. By default the "Location" column is not visible and I have to set it to visible through "View -> Visible Columns" each time. Is there anyway to make the change permanent?
Some people love icons, but not me. I prefer the file list view. I have stumbled around Ubuntu 10.10 trying to find where to set this preference, but have had no success so far. In windows, you would set the preferred view and then apply to all folders. Ubuntu does not follow this paradigm, and indeed, why should it? I have searched the preferences in Ubuntu, and did a global search f this site for related topics. I know you have to be able to do this, I just don't know how. This is the type of topic I will probably kick myself for when someone shows me how easy it is to do. If you don't know how to do it though, it is still black magic.
I'm trying to install kweather in 11.2. I have downloaded and installed. I can find it in usr/bin and usr/lib but I can't add an application as in 11 or 11.1. It doesn't show up in the list of apps. It's there but I can't get it on the desktop.
I'm running Redhat 5 Enterprise (Nautilus 2.16.2) with Gnome and am having trouble changing the default application for PDFs. No matter what I do, it seems to always come up as evince.
First I tried browsing to a PDF file using Nautilus, right clicking on a PDF file, selecting properties, open with, and then changing the radio button. However, the radio button is selecting "Document Viewer" and clicking on the other buttons doesn't do anything. The button is stuck on "Document Viewer" (I'd like to use Adobe Acrobat).
I thought I'd do it manually then. Running `gnomevfs-info file.pdf" shows code...
So now xdg-mime and gnomevfs-info are showing different default applications for this file type. I've tried updating the mime database using update-mime-database ~/.local/share/mime as well as updating my desktop database using update-desktop-database ~/.local/share but nothing seems to be working.
Changing a default application really shouldn't be this difficult. What should I try next to change my default application?
, however, shows something different
My .local/share/applications/defaults.list file, however, shows the following:
I am looking for a default, or starting "exclude list" for system backups. We are currently using Symantec Backup Exec, but I also do not think that is important to this question. I would think that the Oracle "lock" files and the /var/run/*.pid files can be excluded from the backup, and probably the dell file also. Can some provide a list of files/directories that can be excluded (from backup) for RHEL 5?
