You know how to install deb packages with apt-get cmd. But sometimes you need to find the package provides a specific file or executable.
RedHat or CentOS users have this command by default via yum cmd.
yum whatprovides updatedb
This command outputs all packages provide updatedb file (in that case it is an executable).
Ubuntu and Debian users need to install a package to have similar search capability.
First of all you need to install apt-file package:
sudo apt-get install apt-file
Then you need to fetch packages and their contents for the apt-file command to work:
sudo apt-file update
And you can now search within packages (not in package names or descriptions like apt-cache command)
sudo apt-file search updatedb $ sudo apt-file search updatedb augeas-doc: /usr/share/doc/augeas-doc/lenses/files/tests/test_updatedb-aug.html augeas-doc: /usr/share/doc/augeas-doc/lenses/files/updatedb-aug.html augeas-lenses: /usr/share/augeas/lenses/dist/tests/test_updatedb.aug augeas-lenses: /usr/share/augeas/lenses/dist/updatedb.aug locate: /usr/bin/updatedb.findutils locate: /usr/share/man/man1/updatedb.findutils.1.gz manpages-es-extra: /usr/share/man/es/man1/updatedb.1.gz manpages-ja: /usr/share/man/ja/man1/updatedb.1.gz manpages-pl: /usr/share/man/pl/man1/updatedb.findutils.1.gz mlocate: /etc/updatedb.conf mlocate: /usr/bin/updatedb.mlocate mlocate: /usr/share/man/man5/updatedb.conf.5.gz mlocate: /usr/share/man/man8/updatedb.8.gz nss-updatedb: /usr/sbin/nss_updatedb nss-updatedb: /usr/share/doc/nss-updatedb/README nss-updatedb: /usr/share/doc/nss-updatedb/changelog.Debian.gz nss-updatedb: /usr/share/doc/nss-updatedb/copyright nss-updatedb: /usr/share/man/man8/nss_updatedb.8.gz roundcube-core: /usr/share/roundcube/bin/updatedb.sh vim-runtime: /usr/share/vim/vim74/ftplugin/updatedb.vim vim-runtime: /usr/share/vim/vim74/syntax/updatedb.vim
