[SOLVED] Lets say I want to remove all SBo packages (I don't)

moisespedro · 12-02-2014, 04:28 PM

How would I do it? From the command line, all at once?

For example when I run:

Code:

ls /var/log/packages | grep SBo

I get:

Code:

acpica-20140926-i486-1_SBo
apulse-0.1.3-i486-1_SBo
atkmm-2.22.7-i486-1_SBo
atom-0.150.0-i486-1_SBo
bullet-2.82-i486-1_SBo
cairomm-1.10.0-i486-1_SBo
docker-1.3.1-i486-1_SBo
docutils-0.11-i486-1_SBo
dvtm-0.13-i486-1_SBo
ffmpeg-2.1.5-i686_custom-1_SBo
glibmm-2.36.2-i486-1_SBo
google-go-lang-1.3.3-i486-2_SBo
gparted-0.19.0-i486-1_SBo
gst1-plugins-base-1.4.1-i486-1_SBo
gstreamer1-1.4.1-i486-1_SBo
[...]
spotify32-0.9.4.183.g644e24e.428-i386-2_SBo
tamsyn-font-1.10-noarch-1_SBo
transmission-2.84-i486-1_SBo
valgrind-3.10.0-i486-1_SBo
virtualbox-4.3.18-i486-1_SBo
virtualbox-extension-pack-4.3.18-i486-1_SBo
virtualbox-kernel-4.3.18_3.17.2_smp_zram-i486-1_SBo
x264-20131101-i486-1_SBo
xfburn-0.5.2-i486-1_SBo

How would I pass this output as an argument to removepkg?

I tried:

Code:

ls /var/log/packages | grep SBo >> list
for i in list do;
removepkg $i;
done

It didn't work and even if it did I know already it is not the best way. I am sure there is a way to pass the result of "grep" directly to removepkg. How?

Found out I just had to use xargs

Code:

ls /var/log/packages | grep SBo | xargs removepkg

Is there a better way to do this?

removepkg /var/log/packages/*SBo

You also can run:

Code:

slackpkg clean-system

which though is a GUI in ncurses, is still technically a cli tool.

Yes , but be aware that will propose you to remove not only SBo packages but more generally all packages non shipped in the Slackware distribution, so use with care.

SBo packages were just an example, I just wanted to know how to pass the output as an argument (found out I can do that with xargs).

You probably should also use the blacklist file provided when you use self-maintained packages.

I have several custom packages I use which are updated only at my discretion blacklisted for just such a reason.

SBo is commented out by default in /etc/slackpkg/blacklist:

Code:

# You can blacklist using regular expressions.
#
# Don't use *full* regex here, because all of the following 
# will be checked for the regex: series, name, version, arch, 
# build and fullname.
#
# This one will blacklist all SBo packages:
#[0-9]+_SBo
#
# Alien Bob's packages
[0-9]+alien
#
# ruario's latest-firefox
[0-9]+ro
#
# Nouveau
xf86-video-nouveau
