Disk cleanup

[e-hawk]

Hello!

Every time after upgrade I use equo cleanup, but recently I noticed, that free disk space suddenly reduced by approx. 600-700 Mb. I'd like to know the reason. My usual work could not use such amount of disk space and I didn't install any new packages, except usual upgrade. Any suggestions where to start?

do you use only entropy (equo/sulfur) or you use portage too (emerge)?

Just Sulphur.

Try to execute this script:

Code: Select all

#!/bin/bash

if [ $UID -ne 0 ]; then
   echo "You have to be root in order to get better results" >&2
fi

DIRS=$(ls -m /)
DIRS=${DIRS//","/""}

for D in $DIRS; do
D=/$D
if [ -d "$D" -a "$D" != "/proc" ]; then
   USAGE=$(du -h "$D" 2>/dev/null)
   if [ $? -eq 0 ]; then
      printf "%s" "$USAGE" | grep -E '[[:space:]]'"$D"'$'
   else
      echo "Failed to get $D directory Disk Usage (probably permissions were denied)" >&2
   fi
fi
done


This is a little script I made to list the disk space occupied by each directory in /, you should execute it as root to be able to walk in any directory.

You should copy it to a text file and make it executable to run it.

You should get a result like:

Code: Select all

5,3M   /bin
13M   /boot
472K   /dev
16M   /etc
25G   /home
16K   /install-data
196M   /lib
8,0K   /media
40K   /mnt
254M   /opt
108M   /root
18M   /sbin
8,0K   /scripts
0   /sys
48K   /tmp
7,6G   /usr
1,2G   /var


The output could be useful to determine what is taking so much space...

if you run equo cleanup regularly I can only think about an installed application that installed many dependencies (like a KDE application in a Gnome system) or about logfiles growing too large.
In the second scenario you could install logrotate, that utility is awesome.
To cleanup your system you could also be interested in the:

Code: Select all

equo unusedpackages


command, it lists packages that are not dependency of any other package, but be careful, because this does not mean that they are useless.

Thank you, your script worked like a charm. Logs are OK and I didn't install anything at all. Just upgrades. And I am KDE user I've checked almost everything right now. Now I'm checking /usr folder, and I am thinking about kernel upgrade. Could it be the reason? I see /usr/src folder (about 300 MB), is it OK? I've also noticed, that KDE cache folder is about 300 MB (home folder), but it seems inevitable.

Try to run from a console:

Code: Select all

equo query installed linux-sabayon


it should list any kernel and kernel sources installed in your system, I think that the linux sources could take up that space, or maybe you have 2 versions of the kernel installed...

But how much space is wasted?

The output is:

So everything is OK, Iguess.
At least 600 MB was wasted. May be 700 MB.
