To fetch the new lists of all the packages from sources.list enter as root # apt-get update This command checks for new release-files on the given servers. Luckily the command is clever enough to check if the release-file has changed after the last update. ===Upgrade of all the files: To make an update of all the changed packages, enter the line # apt-get update -u The additional flag -u shows a list of upgraded packages as well. If you want to run the update in a cron-job, you should use the flags -dy. With this flags the new packages will be downloaded but not installed. You can install them later by writing apt-get update -u. ===Distribution Upgrade of all the files: To make an upgrade of your actual distribution (e.g from potato to woody or when using unstable) replace upgrade with dist-upgrade when entering your command. So you have to type apt-get dist-upgrade -dy apt-get dist-upgrade -u for an distribution upgrade. ===Add a package: How can you add a package to your system without the gui-programms? All you have to do is find out the name of this package and enter the command apt-get install sylpheed-claws to add the package sylpheed-claws. ===Remove a package: To get rid of the package foo which is no longer needed, enter the command # apt-get remove foo If the package is needed by other packages you will be prompted to remove this package and all packages which depend on it. ===Forced removing of a package: While making an distibution upgrade it coud happen that you have to remove a package first. But sometimes this is not possible with apt-get remove since the package has unmet dependencies or is not installed completely. You can remove the package foo by using the command dpkg --force-all --remove foo ===Read the contents of a installed package: Sometimes you wan't to know which files are in the package foo. To get this information enter the command dpkg -L foo ===Get the description of a package: You don't know what the package foo is for? Just write dpkg -p foo ===Search the package of a file: Have you ever wondered to which package belongs a given file? To get this information (e.g. for /usr/bin/apt-get), start the command dpkg -S /usr/bin/apt-get and it will tell you that this file is part of the package apt. |
