(Debian/Ubuntu) Discover what package a file belongs to

dpkg -S /usr/bin/ls
'dpkg -S' just matches the string you supply it, so just using 'ls' as an argument matches any file from any package that has 'ls' anywhere in the filename. So usually it's a good idea to use an absolute path. You can see in the second example that 12 thousand files that are known to dpkg match the bare string 'ls'.
Sample Output
user@host:$ dpkg -S /bin/ls
coreutils: /bin/ls
user@host:$ dpkg -S ls | wc -l

If you need regex, apt-file -x search /some/file

apparently dlocate is much faster for this if you find yourself needing to do a lot of sleuthing.

This will do the opposite, what files a package generated during installation. dpkg -L packagename

The above are for apt based systems. For portage on gentoo, you need the app-portage/gentoolkit package installed and do equery belongs /some/file

I used grep to filter, and that additionally gives (A) all symbolic link (with the same name) installed by the package as well, (B) other files/directories with the same name installed by other packages. if that info is of any use to you. Example and output will make it more clear: Example: dpkg -S ip | grep "/ip$" Output: linux-headers-2.6.27-7-generic: /usr/src/linux-headers-2.6.27-7-generic/include/config/ip iproute: /bin/ip iproute: /sbin/ip First line of the output is a directory by name ls intalled by the package linux-headers-2.xxxx Second line is the executable by name ip The last line of the output is the symbolic link to the command ip You need to replace both instances of string ip with the command/file of your interest in my example command.

Typo: First line of the output is a directory by name ls intalled Read: First line of the output is a directory by name 'ip' installed

You might want: dpkg -S `which ls` You might know the command but not the full path, i.e. on Ubuntu 11.10: which ls /bin/ls So your command would't actually tell you what package ls comes from on this distro.

in the redhat world this is similar to rpm -qf fllename. I just learned this for debian based systems today. It's useful.
