Get list of packages not in base system

abesirovic1 · 11-02-2010, 09:40 PM

Hey all,

Is it possible to get a list of packages installed on the system that are not a part of Slackware (i.e. take all installed on system, take all packages that originally come with slack, find difference)?

Worthy to mention is that I use slackpkg and run -current.

Thanks lots.

You can use 'slackpkg clean-system' to show you the packages installed that are not part of the official Slackware tree.

From slackpkg manpage:

Quote:

clean-system
This action removes all of the packages that don't belong to a standard Slackware installation. With this option, you can clean up your system,
removing third-party packages as well as any packages that were removed from the official Slackware package set.
If you have some third party (or custom built) packages that you would like to keep, you can temporarily add them to the list of blacklisted packages
before you run the 'clean-system' action.

I don't want to remove any packages nor a clean install, just to see packages I have installed by hand.

No packages will be deleted unless you say to do so. You can still scroll through the list and when done just select cancel.

I do slackpkg clean-system to see the third party packages installed on my Slack. However, I found it hard to dump the list into a text file. I resorted to running it, then cancel. Copy and paste to a text file then repeat again scrolling down for the next line until all packages are copied to text file.

With 78+ packages currently I have, is there a better way of dumping those list somewhere. I cannot see such option on the man page.

Use slackpkg

Code:

$ generate-template installed

This will give you a list of installed official Slackware packages in /etc/slackpkg/templates/installed. But you'd still have to do some cutting and grepping and diffing to compare with the output of

Code:

$ ls /var/log/packages

as external packages usually come with custom tags, to see them you can also filter the standard ones out with a regexp

Code:

ls -1 /var/log/packages/ | grep -v '\-[0-9]\{1,2\}$'

on my laptop (running 64-current)

Code:

# ls -1 /var/log/packages/ | grep -v '\-[0-9]\{1,2\}$' | wc -l
653

I'm not sure if this still works (I checked it in a previous release...either 12.2 or 13.0 and it still did), but I recall this thread, which mentions this:

Code:

slackpkg -dialog=off -batch=on -default_answer=no clean-system > NonSlackwarePackages.txt

There is also this thread for those who do not wish to use slackpkg.

thanks for the links, very interesting threads

I'll dive into them.

T3slider: That works!

Thanks

Just to show another way to skin the cat.
This script uses the PACKAGES.TXT file that slackpkg creates.
It will also show packages that are blacklisted in /etc/slackpkg/blacklist

Code:

#!/bin/bash

# Script to list non-official installed packages
# Official packages are referenced from PACKAGES.TXT created by slackpkg
# Installed packages are referenced from contents of /var/log/packages/

for PKG in /var/log/packages/* ; do
  if ! grep -q ${PKG##/var/log/packages/} /var/lib/slackpkg/PACKAGES.TXT ; then
    echo ${PKG##/var/log/packages/}
  fi
done
