14.04 - a command to list all packagas installed on the system and their installed files, how? - Ask Ubuntu

i using ubuntu 14.04 lts, trusty. want execute command list installed packages of system , each packages name , should list files package has installed on system. how can that?

you can run following command print information in terminal:

for in $(echo $(apt list 2>&1| grep installed | sed 's|/.*$||g')); echo $i; dpkg -l $i | grep -p '^.'$i'|$'; done | tee aptinstalled | grep -p '^[a-z0-9].*$|$' 

the command creates file information named aptinstalled.

alternatively, if list of files of installed package, can run command dpkg -l followed package name.

for example, list files installed package gnome-terminal, run following command:

dpkg -l gnome-terminal 

if want list installed packages, can run following command:

apt list 2>&1| grep installed | sed 's|/|  |g;s|\[.*$||g' | grep_color='0;32' grep --color=auto -p '^.*  ' 

if want list installed packages without information, can run instead:

apt list 2>&1| grep installed | sed 's|/.*$||g' 

if list installed package names in linear form instead of column, can run following command:

echo $(apt list 2>&1| grep installed | sed 's|/.*$||g') 

finally, if list installed packages , brief description of each package, run following command:

dpkg -l | grep --color=always ii 

the last command highlight "ii" in red printed directly before each package name make easier distinguish between package names , descriptions.

or, run following command instead:

dpkg -l

additionally suggested @steeldriver in comment, can use -f flag dpkg-query command print name. here's example:

dpkg-query -w -f='${package}\n' | while read -r p; echo "$p" & dpkg-query -l "$p"; done 

and here package name highlighted in green:

dpkg-query -w -f='${package}\n' | while read -r p; echo "$p" & dpkg-query -l "$p"; done | grep_color='0;32' grep -p --color=auto '^[a-z0-9].*$|$' 

and here in form of script create new directory ~/packagefiles. executing script create text file each package installed in new directory. each text file contains list of files each package. print in terminal normal, each package name highlighted in green:

#!/bin/bash mkdir -p /home/$user/packagefiles 2>&1 dpkg-query -w -f='${package}\n' | while read -r p; echo " $p" & dpkg-query -l "$p" | tee /home/$user/packagefiles/"$p"; done | grep_color='0;32' grep -p --color=auto '^[a-z0-9].*$|$' 

this convenient because each package listed in directory , ls ~/packagefiles list packages in nice columns.

don't forget make script executable.
