Debian-goodies is a package that includes toolbox-style utilities used to manage Debian and its derivative systems such as Ubuntu, Kali Linux. The utilities under this package are developed in such a way to combine with many recognized shell tools and others are included because they cannot be developed as their own packages on Debian-based Linux distributions.
8 Debian Goodies Utilities to Manage Debian Packages
In this guide we shall look at how to use the utilities under the debian-goodies package which include dglob, debget, dpigs, dgrep, debmany, checkrestart, popbugs and which-pkg-broke.
Let’s see the description of each tool below:
- dglob – Produce a list of package names which match a pattern
- dgrep – Search all files in given packages for a regex
- dpigs – Display which installed packages taken the most disk space
- debget – Obtain a .deb for a package in APT’s database
- debmany – Choose manpages of installed or removed packages
- checkrestart – Finds and restart processes which are using outdated versions of upgraded files
- popbugs – Show a customized release-critical bug report based on packages you use
- which-pkg-broke – Catch which package might have broken another
These are very useful utilities that can make System Administration a lot more easy when used with other shell tools. In-fact, Debian-goodies tool shows more information about packages than standard tools such as dpkg and apt tools.

5. How to Use debmany Utility
It is used to select the manual entry pages of installed or uninstalled packages on your system. This utility allows you to view all the manpages of a package.
Some of the following options you can use with debmany to display the manpage using your viewer of choice:
If you use KDE desktop environment, use -k option to use kfmclient.
[email protected]:~# debmany -k tar
Note: I don’t have KDE DE installed on my system, so it’s difficult to show output of the above command.
If you use GNOME desktop environment, use -g option to use gnome-open.
[email protected]:~# debmany -g tar
View Man Pages of Installed Packages
If you use KDE/GNOME/Xfce desktop environment, use -x option to use kdg-open.
[email protected]:~# debmany -x tar
Make sure that the above viewers are installed before you can use them or else you may get an error.
6. How to Use checkrestart Utility
The chechstart is used to find and restart processes that are using old versions of files that have already been upgraded.
To use checkrestart with all processes, use the -a option.
[email protected]:~# checkrestart -a
lsof: WARNING: can't stat() fuse.gvfsd-fuse file system /run/user/1000/gvfs
Output information may be incomplete.
Found 30 processes using old versions of upgraded files
(28 distinct programs)
(23 distinct packages)
Of these, 1 seem to contain systemd service definitions or init scripts which can be used to restart them.
The following packages seem to have definitions that could be used
to restart their services:
openssh-server:
1947 /usr/sbin/sshd
1889 /usr/sbin/sshd
These are the initd scripts:
service ssh restart
...
To specify only process deleted files that are attached to a given package on the system, use the -p option.
[email protected]:~# checkrestart -p
lsof: WARNING: can't stat() fuse.gvfsd-fuse file system /run/user/1000/gvfs
Output information may be incomplete.
Found 0 processes using old versions of upgraded files
You can generate a detailed output information by using the -v option.
[email protected]:~# checkrestart -v

7. How to Use popbugs Utility
It is used to show a list of customized release-critical bugs based on the packages you commonly use on your system. When you run popbugs without any option for the first time, it will show you a message such as the one below.
[email protected]:~# popbugs
There is no popularity-contest data present on your system. This
probably means that popularity-contest has not yet run since it
was installed. Try waiting for /etc/cron.daily/popularity-contest to
to collect some data or manually run (as root user):
/usr/sbin/popularity-contest >/var/log/popularity-contest
To generate the popularity-contest log, run this command below.
[email protected]:~# /usr/sbin/popularity-contest > /var/log/popularity-contest
To store output in a file, use the –output=/path/to/file option. The output file should be a html file.
[email protected]:~# popbugs --output=/tmp/output.html
To view the output file open the file from the web browser by specifying the file location.
