HowTo get rid of GUIs to save space? knoppix takes 8gigs!

**MemMaker** · 10-19-2003, 01:18 PM

Hi,
I am hoping to find a solution to the following problem:
after the knoppix hd install on a p133 with 96mb ram and
8gb scsi hdd and fiddling around with the apt-get upgrade options,
my linux system apparently (when i select all files on a windows box
over samba shares and rightclick for the filesize) takes up all of
the 8 gb of hdd-space I have. I only installed a few packages (apache2,
centericq, qwsv & ddclient).

1. Question: Can this be?
which linux command do I have to use find out about
the disk space usage?
2. is there a way to completely strip the
kde, xfree86, gnome, etc. GUI-stuff from debian/knoppix?

I am running this on a box which shall in the future run without
a monitor, so i won't use graphic intense applications, besides
of the missing cpu power..

Does anyone have some suggestions?

1. Question: Can this be?

It's pretty damn unlikely. It seems to me that the 8Gb is simply the size of the partition.

To find out how much of it is full, use KDeiskFree.

I'm not sure what you're trying to do by pulling the GUI's off. Seems pretty drastic.

df -h in a console window.

apt-get --purge remove kdelibs4 kdebase libarts xserver-xfree86 xserver-common xlibs gnome-common

For anything left over dpkg --get-selections > selections.txt then edit the file and remove the lines of any other programs you do not want then dpkg --set-selections < selections.txt to import the package list and dselect update to update the package system then apt-get deselect-upgrade to upgrade to the packages in the list. After you are done you may want to run orphaner if it has not been removed and get rid of any old libraries left laying around and not in use, if it has been removed then apt-get install deborphan

You can also use df from the command line to check out disk space.

--What in the world... Let me get this straight. You mounted your linux box's filesystem over **samba shares** and checked the disk space from WINDOWS

(sputter)
(speechless)

--I recommend finding a LUG (Linux Users Group) in your area as fast as possible, you've definitely been hanging around Windoze too long.

--Okay, just joking

, enough teasing. To check disk space for a specific directory (if you use / , it will check the whole system) use du. ' man du '

--Typical syntax:
' du -s -h /usr ' == Summary of /usr, in human-readable format
' du --max-depth=2 /home ' == See usage of /home/user1, /home/user2...
' du -h --max-depth=1 / ' == See usage of each dir hanging off of root

--And as others have mentioned, use ' df ' for usage of mounted filesystems/partitions. It also accepts the ' -h ' flag.

Thanks for the replies, i got the follwing output for "df -h":

Code:

[root@xserver]:[root]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda1             8.1G  1.1G  6.7G  14% /
/dev/root.old         2.2M  235K  2.0M  11% /initrd

There's one thing I wonder about, why's there a difference between used+
avail. compared to disksize? Is this because of the fs?

So I see i got plenty of space left on my hdd.. just a commom mistake..

I am stripping the GUIs because I want a slim machine and get
some knowledge about linux in general, also the mentioned system
(p133, 94mb ram, 512kb vga) would be to slow for the big one
like gnome and kde and so I decided to be a little more drastic.

@dave_bechtel
;p - not really, I didn't connect my windows machine to the linux
over samba just to check the filesize, it already was connected
so because the linux box acts as router/gateway for my win2k pc.

@stephen
thanks for the purging commands..
well I got one mor Question about this:
How do I get apt-get do remove the
configuratoin dirs even when they aren't
empty?

Making sure that you are removing the right directory or you will screw up the system rm -rf /non/empty/directory/tree. I usually check just to make sure that it is only the configuration files left some packages don't clean up as well as they should and orphan the config files, it is usually only one or two files left in the whole directory tree anyway so you could just leave them there if you want.

--Most likely the -h flag is doing some rounding.

Code:

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/hde3              2298164    997984   1300180  44% /

Filesystem            Size  Used Avail Use% Mounted on
/dev/hde3             2.2G  975M  1.3G  44% /

--Using the second result, (1300*1024)+(975*1024) == 2329600, which is above the actual filesystem size. Even the actual (fdisk) size of the partition is only 2298240. If you need precice measurements, df w/o the -h flag gives the right results.

--FYI, I'm using reiserfs. If you're using ext2/ext3, a certain percentage of the fs is reserved for root (use tune2fs to check / modify == ' tune2fs -l /dev/blah ' to look ; ' tune2fs -m 1 /dev/blah ' to set reserved to 1%.)

@stephen
The by-foot-way is what I wanted to avoid. I thought there
could be an easier possibility, e.g. something like:
"purge all non-empty removed-package config-dir".
But thanks anyway.

@dave
yes, i am using ext2. What are the differences, between
reiserfs, ext2 & ext3..? what would you recommend?
