For example: sudo cp /etc/apt/sources.list /etc/apt/sources.list~  With this command I not see any changes. What does the final tilde do?

In Windows, I believe that files with a tilde in the file name represent files that are currently open in an application. For example, Microsoft Word creates a file with almost the same name as the file you currently have open, but with a tilde in the name. It's icon is also partially faded. As far as I'm aware, this signifies a temporary file that exists   in case the application crashes and you didn't get a chance to save your file, or to allow the original file to remain unlocked by the file system and accessible to other applications.   In Linux, I ran into a *.log file with a tilde at the end of the file name (scan.log~). Does that mean the log file is currently open in another application that is potentially writing to it?

Of course when you type:  sudo apt-get install whatever   It asks you:   Do you want to continue [Y/n]?    Is there any way I can just install it without it asking me if I want to continue? I don't really care about space, I have more then enough.

Is there a way to show the history of packages that were changed by apt-get via command line?

Okay, I understand how I may use apt-get {install|upgrade|remove} mypackages to install, upgrade, or remove binaries as well as their configuration data files and dependencies (actually, remove will only remove the binaries unless additional flags are provided).  I am not looking for how it is used as the man describes this, but high level what it is doing.  My end goal is to create a means for me to install and manage some custom software (created by a make file) on multiple remote machines, and I need to learn more about the process.  If answers to this question are based on which distribution is used, please tailor to Debian.  In addition to generally how it works, I have the following specific questions:   How does the client that is accessing the apt repository keep track of the files? Must the repository be hosted on the same operating system (i.e. can apt repository be hosted on redhat)? How are the locations to install files specified?  Is this specified by the .deb file? How is a remote machine accessing the repository?  Is it just ftp(s) or http(s)? Is the machine that is hosting the repository running special software (like gitlab for a git repository), or is it just some structured file system?

I would like to create a symlink to ~/foo/ but when I write that, ~ is always resolved to the absolute home path. I've used ../s in the past and they work fine, is ~ not allowed?  The reason I'd like to do that is because ~ has a different absolute path depending on the machine and Linux/OSX, but always points to my home directory.  I'd like to include such a link in a git repo sync'd across several machines.

If the which command is not available, is there another 'standard' method to find out where a command's executable can be found?  If there is no other 'standard' method available, the actual system I face currently is a bare Android emulator with an ash , if that means anything.

I saw this snippet in some installation instructions:  $ apt-get install update   I know what apt-get install XXXX does and I know what apt-get update does, but I can't find any info on what this combined statement does. What does it do?

As we know that we are using  for installing packages and repositories configuration file located at /etc/apt/sources.list.  I am using Ubuntu 12.10 (Quantal Quetzal) which reaches . That means no updates or support. So, the question is, can I use sources.list file from another version, say Ubuntu 12.04 LTS, and will it negatively affect the system.

I've searched the net for such information and found different command lines, like these ones:  sudo apt-get remove application sudo apt-get remove application*  sudo apt-get remove --purge application sudo apt-get remove --purge application*  sudo apt-get purge application sudo apt-get purge application*   So, what is the correct way? Is it necessary to use that "*"?  After that, I also found these commands:  sudo updatedb sudo locate application sudo rm -rf (file/folder name)

It often happens that I have to watch this screen for minutes:    I have no clue what's happening in the back. And I'm also not interested in watching the  for changes.  I would love to know if there's a way that gives more feedback. Preferably something I can invoke from the command line (like apt-get).

As time goes by we tend to do apt-get install and add or replace software.  Are these archived in some form or do they get auto-cleared after installation? And if it doesn't get auto-cleared, it would mean that a clean up is needed, isn't it?  Finally, if they're not auto-removed, can we reuse these packages on different machines?

In my terminal prompt definition in my .bashrc file, among other things, I have this snippet of code:  ${debian_chroot:+($debian_chroot)}   What does this do, and do I need it?

For instance, netstat. This doesn't show up when you type help, but netstat /? does provide the information.  Are there any other commands that will not get listed?  Also, the command netstat /? &gt; netstat.txt won't work. Any idea why? The netstat.txt file is created but remains empty.  I have write-permission on the map and the CMD.EXE is running as admin.

I tried to add a new repository to software sources, but "add source" button is unavailable. I can't click on it.  I also tried to add a new software source from the terminal, but it didn't work.  sudo‬‬ ‫‪add-apt-repository‬‬ ‫‪ppa:n-muench/burg‬‬   s‫‪udo‬‬: command not found     I also tried these commands:  ‫‪sudo‬‬ ‫‪add-apt-repository‬‬ ‫‪deb‬‬ ‫‪http://ppa.launchpad.net/n-muench/burg/ubuntu‬‬ natty‬‬ ‫‪main‬‬   sudo‬‬: command not found

I've added many PPAs using the add-apt-repository command. Is there a simple way to remove these PPAs? I've checked in /etc/apt/sources.list for the appropriate deb lines but they aren't there.   This is on a server system so a command line solution would be great!

We know that do-release-upgrade “does a release upgrade”. But at a little lower level what does it really do?  I plan to do a more manual upgrade, for instance the Debian way: aptitude update and aptitude full-upgrade after setting up the sources. Actually, I plan to do it entirely interactive with aptitude. But that leaves me curious about what else do-relase-upgrade does, except hosing up my sources.list.

I have successfully installed some packages using the command line 'sudo apt-get install packagename' when I have known in advance that those packages are available.  But how can I search for or get a list of what is available in the repositories?
