List Packages in Ubuntu using dpkg

To list the packages in ubuntu you can use the “dpkg” command. This is the debian package manager. Ubuntu uses it since it is debian based.

computer@computer:~$ dpkg --list
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name               Version            Description
ii  accountsservice    0.6.14-1git1       query and manipulate user account information
ii  acl                2.2.51-3           Access control list utilities

This will produce a list of packages installed on the system. This an be combined with the grep command to find a specific package

computer@computer:~$ dpkg --list | grep vim

ii  vim-common                             2:7.3.154+hg~74503f6ee649-2ubuntu3      Vi IMproved - Common files
ii  vim-tiny                               2:7.3.154+hg~74503f6ee649-2ubuntu3      Vi IMproved - enhanced vi editor - compact version
