Is there a generalised way to find out what package caused the installation of a command?

Open a terminal and try the following commands:

dpkg -S 'command name'

eg: dpkg -S /bin/ls

Sample output:

coreutils: /bin/ls

You can also obtain detailed status information about coreutils package, enter:

 dpkg -s coreutils

Sample output:

From the command name you can use the 'type' and 'dpkg' commands to determine the package which is responsible for their installation. For example to find out which package installed the command 'who' you could do the following commands at a command prompt:

$ type who
who is /usr/bin/who
$ dpkg -S /usr/bin/who
coreutils: /usr/bin/who

there is another one method, maybe a little silly, but faster than previous ones :) just mistype a command and you will get correct command name and package it came from.

Sample output:

pawel@pawel-desktop:/var/www$ sfn
No command 'sfn' found, did you mean:
 Command 'sn' from package 'mono-devel' (main)
 Command 'sfc' from package 'syfi-bin' (universe)
 Command 'svn' from package 'subversion' (main)
sfn: command not found

That is indeed very silly! – LassePoulsen Nov 18 '10 at 10:56
but it works :P – Paweł Karpiński Nov 18 '10 at 11:53

You can also do it with one line:

dpkg -S $(which command)

For example, I want to know what package contains ls:

dpkg -S $(which ls)

And here is the output:

coreutils: /bin/ls

So now I know that ls command, /bin/ls file, comes from coreutils package.

Now for a completely different approach.

Go to and follow your nose. In particular, scroll down to "Search the contents of packages" and enter the file name or system command.

  1. drop to a command prompt (Menu > Applications > Accessories > Terminal)
  2. enter dpkg-query --search 'command' where 'command' is the command whose owning package you're trying to find.
