-
(also works on Ubuntu) Copies the 'install,' 'hold,' 'deinstall' and 'purge' states of packages on the remote machine to be matched on the local machine. Note: if packages were installed on the local machine that were never installed on the remote machine, they will not be deinstalled by this operation.
27ssh remotehost 'dpkg --get-selections' | dpkg --set-selections && dselect install -
Limits the usage of bandwidth by apt-get, in the example the command will use 30Kb/s ;) It should work for most apt-get actions (install, update, upgrade, dist-upgrade, etc.)
18sudo apt-get -o Acquire::http::Dl-Limit=30 upgrade -
13apt-get install `ssh root@host_you_want_to_clone "dpkg -l | grep ii" | awk '{print $2}'`
-
Requires: imagemagick and graphviz On Debian systems, displays a graph of package dependencies. Works also with other image formats, like svg :
apt-cache dotty bash | dot -T svg | display9apt-cache dotty apache2 | dot -T png | display -
Shows all configurations to apt and dpkg, rarely changed, you probably still have the default configuration. Go ahead and explore your configuration if you dare, perhaps change your apt-cache directory, Dir::Cache "var/cache/apt/"; or the names of the log files. Show Sample Output
6apt-config dump -
3apt-get --just-print upgrade
-
3dpkg -l

Change the APP variable's value to whatever you want to install. Depending on how fast your machine is, you'll want to adjust the value 50 to something else. You might also want to play a different game than Gnometris - just make sure it's a GUI game.
2APP=wine; if [ $(sudo apt-get --print-uris -y install $APP | sed -ne 's/^After this operation, \([0-9]\{1,\}\).*MB.*/\1/p') -gt 50 ]; then gnometris 2>/dev/null & sudo apt-get install $APP; else sudo apt-get install $APP; fi -
This script compares the modification date of /var/lib/dpkg/info/${package}.list and all the files mentioned there. It could be wrong on noatime partitions. Here is non-oneliner: #!/bin/sh package=$1; list=/var/lib/dpkg/info/${package}.list; inst=$(stat "$list" -c %X); cat $list | ( while read file; do if [ -f "$file" ]; then acc=$(stat "$file" -c %X); if [ $inst -lt $acc ]; then echo used $file exit 0 fi; fi; done exit 1 ) Show Sample Output
1package=$1; list=/var/lib/dpkg/info/${package}.list; inst=$(stat "$list" -c %X); cat $list | (while read file; do if [ -f "$file" ];then acc=$(stat "$file" -c %X); if [ $inst -lt $acc ]; then echo used $file; exit 0; fi; fi; done; exit 1) -
Shows the packages installed on your system that are recomemnded by other packages. You should remove these packages. Show Sample Output
1aptitude search '?and( ?automatic(?reverse-recommends(?installed)), ?not(?automatic(?reverse-depends(?installed))) )' -
Replace \-dev with whatever you wanna search for
1dpkg-query -Wf '${Installed-Size}\t${Package}\n' | grep "\-dev" | sort -n | awk '{ sum+=$1} END {print sum/1024 "MB"}' -
In this case, linux- is the prefix; simply running
apt-cache pkgnameswould list every package APT knows about. The default APT config assumes -g, --generate; to use the cache as/is, you could similarly run:apt-cache --no-generate pkgnames [prefix]Adding --all-names, like so:apt-cache --no-generate --all-names pkgnames [prefix]would print all the packages APT knows about, using the cache as/is, including virtual packages and missing dependencies. This command was shamelessly stolen from the apt-cache(8) man-page. Show Sample Output1apt-cache pkgnames linux- -
If, for example, you want to remove all kernels and headers but the last three versions, you can't use one of that magic all-in-one "remove old stuff" commands. With this simple but elegant command you can remove a range of versions, or a list of versions with e.g. {14,16,20}. Show Sample Output
1apt purge linux*{14..18}* -
0apt-cache depends <packagename>
-
0apt-cache rdepends <packagename>
-
This will print the name of every installed package on a Debian system.
0aptitude search ~i -F %p -
">>" appends to the file ">" replaces the entire file make sure to use ">>" Show Sample Output
0sudo echo "package url" >> /etc/apt/sources.list -
Removes packages that are recommended by other packages.
0aptitude remove '?and( ?automatic(?reverse-recommends(?installed)), ?not(?automatic(?reverse-depends(?installed))) )' -
Install Ksuperkey one command in Kubuntu. You must manually add ksuperkey to autostart in System Settings KDE.
0sudo apt-get install git gcc make libx11-dev libxtst-dev pkg-config -y && git clone https://github.com/hanschen/ksuperkey.git && cd ksuperkey && make && sudo mv ksuperkey /usr/bin/ksuperkey && cd ~ && rm -rf ksuperkey -
I personally like it very much and have wrapped it into a function, named "apt-propos" ;), also you can use --names-only option for a sort-of "apt-whatis"
0apt-cache search byo | sed "s/^\([[:alnum:]\.-]*\) - /\1=%%%=- /" | column -s '=%%%=' -t -
0apt list --upgradable
-
For instance, to add mongodb 10gen package echo "deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen" | sudo tee -a /etc/apt/sources.list Show Sample Output
-2echo "[some repository]" | sudo tee -a /etc/apt/sources.list -
The legend in the first column: i = installed p = installable Show Sample Output
-6aptitude search NAME
