We noticed that not only Debian-users like Grml but also people coming from the BSD-section, Gentoo-Linux and so on. You don't need any Debian knowledge to use Grml, but if you would like to use the package management you should know some basics. The following table provides a comparison of the package management of Debian compared with some other well known package management systems:
| Action | Debian | Gentoo | RPM | OpenBSD | BSD Ports |
|---|---|---|---|---|---|
| useful tools | apt-file |
app-portage/esearch, app-portage/portage-utils, app-portage/gentoolkit, app-portage/eix |
yum, rpmbuild | ... | ... |
| search for foobar | apt-cache search foobar |
emerge search foobar or esearch foobar |
yum search foobar |
grep foobar index.txt |
cd /usr/ports/ && make search key=foobar |
| show all packages that match 'pattern' | dpkg -S pattern |
qfile pattern or equery b(elongs) pattern |
yum whatprovides pattern or repoquery ––whatprovides pattern |
grep foobar index.txt |
cd /usr/ports/ && make search key=foobar |
| list files in installed $package | dpkg -L $package |
qlist $package or equery f(iles) $package |

emerge -u foobar |
rpm -U $package |
pkg_add -r $package |
... |
| simulate upgrade | apt-get -s upgrade |

... | (before replacing, it is always simulated) |
... |
| simulate installation of package | dpkg -i --no-act $package.deb |
emerge -pv $package | rpm -i --test $package.rpm |
... | ... |
| upgrade the distribution (including dependencies) | apt-get dist-upgrade |
emerge -uD world |
... | run install ISO or Download all Install sets to the local HDD and move the new "bsd.rd" to /bsd. After the reboot choose "upgrade" and install the install sets from HDD. After the installation use pkg_add -u to upgrade your installed software too. |
... |
| install $package | apt-get install $package |

Another frontend and easy to handle system to the debian package management is the ncurses based 'aptitude'. 'aptitude' can also be used in a console-oriented way (like apt-get). Just replace 'apt-get' in the above commands with 'aptitude'. As of Debian Sarge this is even the prefered way to install and upgrade packages, as 'aptitude' is better in handling dependencies.
For handling /etc/apt/sources.list take a look at the apt-howto basics, for further information on package management read chapter 3 of apt-howto.
See grml.org/files/ for instructions how to use the grml-repository. You can use the grml-repos even if you don't use a grml-system but any other Debian system. With introduction of apt-0.6 it's possible to check integrity of the packages. The following warnings will disappear then:
W: GPG error: http://deb.grml.org grml-stable Release:
The following signatures couldn't be verified because the public key is not available: NO_PUBKEY F61E2E7CECDEA787
WARNING: The following packages cannot be authenticated!
For the grml-repository just run:
apt-get --allow-unauthenticated install grml-debian-keyring
or:
gpg --keyserver subkeys.pgp.net --recv-keys F61E2E7CECDEA787
gpg --export F61E2E7CECDEA787 > /etc/apt/grml.key
apt-key add /etc/apt/grml.key
Or if you do not want to store the key in a file:
gpg --keyserver subkeys.pgp.net --recv-keys F61E2E7CECDEA787
gpg --export F61E2E7CECDEA787 | apt-key add -
Or even simpler, in one line:
apt-key adv --keyserver subkeys.pgp.net --recv-keys F61E2E7CECDEA787
