I wanted to view only executables installed by a package. This seemed to work. There's got to be easier way, please share. Note: (1) Replace iptables with the package name of your interest (2) The command will trash any existing environment variable named 'lst' (3) Instead if you are interested in viewing just .ko or .so files installed by this package, then that would be easy: $ dpkg -L iptables | grep "\.[sk]o$" Show Sample Output
1lst=`dpkg -L iptables` ; for f in $lst; do if [ -x $f ] && [ ! -d $f ] ; then echo $f; fi; done; -
If the first two letters are "ii", then the package is installed. You can also use wildcards. For example, .
dpkg -l openoffice*. Note that dpkg will usually not report packages which are available but uninstalled. If you want to see both which versions are installed and which versions are available, use this command instead: .apt-cache policy pythonShow Sample Output1dpkg -l python -

The other commands were good, but they included packages that were installed and then removed. This command only shows packages that are currently installed, sorts smallest to largest, and formats the sizes to be human readable. Show Sample Output
1dpkg-query --show --showformat='${Package;-50}\t${Installed-Size}\n' `aptitude --display-format '%p' search '?installed!?automatic'` | sort -k 2 -n | grep -v deinstall | awk '{printf "%.3f MB \t %s\n", $2/(1024), $1}' -
VPS server hosts suspect DOS attack if PPS is too high. This limits packets at the interface level. Do "sudo apt-get install iptables-persistent" to make persistent, or, if you already have, reconfigure with "sudo dpkg-reconfigure iptables-persistent" Show Sample Output
1sudo iptables -A INPUT -m limit --limit 2000/sec -j ACCEPT && sudo iptables -A INPUT -j DROP -
1sudo apt-get remove --purge $(dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d')

Some command names are very different from the name of the package that installed them. Sometimes, you may want to find out the name of the package that provided a command on a system, so that you can install it on another system. Show Sample Output
1dpkg -S "$(readlink -e $(which w))" | cut -d ':' -f 1 -
Put this one-line function somewhere in your shell init, re-login and try
whatinstalled <command>This is an elaborate wrapper around "dpkg -S", with numerous safeguards. Symlinks and command aliases are resolved. If the searched command is not an existing executable file or was installed by some other means than dpkg/apt, nothing is printed to stdout, otherwise the package name. Show Sample Output1whatinstalled () { local cmdpath=$(realpath -eP $(which -a $1 | grep -E "^/" | tail -n 1) 2>/dev/null) && [ -x "$cmdpath" ] && dpkg -S $cmdpath 2>/dev/null | grep -E ": $cmdpath\$" | cut -d ":" -f 1; } -
0dpkg -l | grep ^rc | awk '{print $2}' | sudo xargs dpkg -P

OS: Debian based (or those that use dpkg) Equivalent to doing a dpkg -S on each file in $PATH, but way faster. May report files generated though postinstall scripts and such. For example . It will report /usr/bin/vim .. which is not not a file installed directly by dpkg, but a link generated by alternatives hooks
0echo -e "${PATH//://\n}" >/tmp/allpath; grep -Fh -f /tmp/allpath /var/lib/dpkg/info/*.list|grep -vxh -f /tmp/allpath >/tmp/installedinpath ; find ${PATH//:/ } |grep -Fxv -f /tmp/installedinpath -
List packages and their disk usage in decreasing order. This uses the "Installed-Size" from the package metadata. It may differ from the actual used space, because e.g. data files (think of databases) or log files may take additional space. Show Sample Output
0perl -ne '$pkg=$1 if m/^Package: (.*)/; print "$1\t$pkg\n" if m/^Installed-Size: (.*)/;' < /var/lib/dpkg/status | sort -rn | less -
0dpkg-query -W -f='${Version}' package-name

on a dpkg managed system this PATTERN will help you generate .deb files from source AND remove all the dev libs you had to install. i hate cluttering up my machine with rouge packages and headers. it would be pretty darn easy on rpm systems as well. i just dont have a rpm managed system to test on right now. NOTE, you sharp ones will notice that it uninstalls the deb you just made! yeah, but the deb is still there to do with it what you want, like re install it. or you can just grep -v after the diff
0dpkg-query -l > 1.lst; sudo apt-get install -y build-essential; ./configure; make; sudo checkinstall -D make install; dpkg-query --list > 2.lst; diff 1.lst 2.lst | grep '^>' | awk '{print $3}' | xargs sudo apt-get remove -y --purge -
Lists all packages in "rc" state and purge them one at a time.
0dpkg -l | grep ^rc | cut -d' ' -f3 | xargs dpkg -P -
0dpkg -S file
-
0dpkg -S locale.alias
-
Similar to command 7822, but handles errors gracefully. Show Sample Output
