Slackpkg is an automated tool to manage local packages and to install new package over a network. Nowadays slackpkg comes as part of Slackware, but if you do not have it installed, the latest version can be downloaded from SourceForge and installed with installpkg.
Before slackpkg can be used it needs to have a current list of packages and their versions and that can be downloaded automatically by the tool itself once a mirror site is selected. To select a mirror, just uncomment a single URL in the file
/etc/slackpkg/mirrors. Note that the links are sorted by Slackware release versions so make sure that the selected link is in the same release that you are interested in.
darkstar~# slackpkg update gpg
The next step would be to update the package list with:
darkstar~# slackpkg update
If there hasn't been a change to the list, you will be prompted with:
No changes in ChangeLog.txt between your last update and now. Do you really want to download all other files (y/N)?
Otherwise slackpkg will download and install the current package information and will use that list.
slackpage will take into consideration any pattern from
/etc/slackpkg/blacklist. For example the following patterns will make slackpkg disregard any package that was installed from SBo and from alienBob's repository:
Slackpkg uses patterns to search install and remove packages. The pattern will be searched on the list of packages and any package that matches the pattern is shown.
Searching a package will show you information about the package full name, version and installed status.
darkstar~# slackpkg search mc Looking for mc in package list. Please wait... DONE The list below shows all packages with name matching "mc". [ installed ] - mcelog-1.0pre3-i486-1 [uninstalled] - pcmciautils-017-i486-1 [ installed ] - mc-22.214.171.124-i486-1 [ installed ] - libmcrypt-2.5.8-i486-1
To search a specific file and later install or remove the package that contains this file:
darkstar~# slackpkg file-search sshd Looking for sshd in package list. Please wait... DONE The list below shows the packages that contains "sshd" file. [ installed ] - openssh-6.0p1-i486-2
To get information about a package
slackpkg Info packagename will print the package's information to the screen.
To install a package use
slackpkg install pattern. If a package was found a dialog window will present any packages that matches to the pattern and the user can un/check which packages to install.
To install everything in a branch you can type:
slackpkg install branch for example
slackpkg install kde will install everything under kde (but nothing from kdei).
To remove a package use
slackpkg remove pattern. If a package was found a dialog window will present any packages that matches to the pattern and the user can un/check which packages to remove.
If an update is available for a certain package, it can be updated with
slackpkg upgrade packagename.
This command can be used if a package became broken and needs to be re-installed.
This can be used to add a certain package to the blacklist. Blacklisted packages are being disregarded by slackpkg.
If you need to re-install the entire system or install a new PC that will have similar installed packages, a user can generate a template to be installed later.
This command is used to have all the packages in a template be installed on this PC.
Running slackpkg with this argument generates a list of packages that were introduces to the Slackware recently, for example new dependencies to a package. It is advisable to run this command before updating the system if you synchronize to slackware-current.
Running slackpkg with this argument will generate a list of all packages that can be upgraded with a new version. The user can un/check which packages to upgrade from a dialog list.
Running slackpkg with this argument will generate a list of all packages that are obsolete and can be safely removed from the system. Note that non-official packages will be listed here unless blacklisted.
During installation a new configuration file might be installed and overwrite your configurations. To prevent that the file will receive a “.new” prefix and after installation slackpkg will inform the user about the existence of these files. Running slackpkg with this argument will search for the existence of these files and will ask the user for instructions.
Running slackpkg with this argument will produce a clean printout if there are any available updates.
