How do I determine how much HDD space my system is using?
I'm not quite certain how to do this on Gentoo KDE.
I tried df:
| Code: |
George bob # df -Th
Filesystem Type Size Used Avail Use% Mounted on
rootfs rootfs 99G 83G 12G 89% /
/dev/root ext3 99G 83G 12G 89% /
rc-svcdir tmpfs 1.0M 76K 948K 8% /lib64/rc/init.d
udev tmpfs 10M 280K 9.8M 3% /dev
shm tmpfs 4.0G 0 4.0G 0% /dev/shm
|
I'm pretty sure I'm not using 200GB. At this point I shouldn't have any multi media files on my system.
Is there a better way of doing this?
Thanks! |

After that, you can find where do you use a lot of stuff with that command :
| Code: |
# du -h /home | sort -h
|
For example |

Ah, that makes sense, I don't know what I was thinking...
I found some more media files in my home directory.
/home/bob is no only 1GB, bringing the root partition down to 22GB used.
Still though, this seems like a lot.
It looks like /usr is about 16.4GB, /var is 2.7GB, and /sys is 1.5GB.
This seems like a lot to me. Why would they be so high? |

I usually use du -xaB1m | awk '$1 >= 200'

Ooo, thanks for the fancy command, d2_racing. I just spent the better part of an hour trying to find it.
Using this new found ability, I did some more investigating:
| Code: |
7.8G /usr/portage/distfiles
4.3G /usr/share
2.3G /usr/lib64
2.2G /usr/share/doc
1.6G /usr/src
924M /var/tmp
1.1G /var/log
1.5G /sys/devices/pci0000:00
|
Is this about right? The reason I am asking is because I am thinking about switching to an SSD, and at about a $1 gig, I am trying to make sure I use the space wisely. |

Bob ...
/var/tmp looks like you have some builds that died, /var/tmp/portage can be cleared of such things. Also /usr/share/doc would seem to me to be fairly large (here its only 113MB). Running 'eclean-dist' might slim down /usr/portage/distfiles (here its 934M). Otherwise it looks ok.
My 'disk use':
| Code: | | du -h --max-depth=0 --exclude='.*' */ | sort -rh |
HTH & best ...

How many packages do you have installed? The /usr/share/doc entry looks absurdly huge -- I'd look into what's contributing to this, in case you either have unnecessary packages installed or something that's gone awry with portage's compression of documentation.
The /usr/src entry looks like you may have a lot of old kernel sources/builds lying around. The older ones should be safe to remove with `emerge -av --depclean` and rm -rf on the remains.
The /var/log looks a bit on the large side, do you have logrotate installed? You may also have packages creating custom logfiles that aren't handled by logrotate that may need custom entries.
The /sys/devices entry is just plain weird to me (though I'm not intimately familiar with the inner workings of /sys). /sys is a psuedo-filesystem and likely isn't consuming any real space, though. |

Thanks, that should be all I needed then.
It looks like will need to make sure I have a good 30GB for Gentoo on my new SSD... |

| Great tip, thanks! That seems pretty neat. I wonder if I can use this when I install Gentoo. Based on the one post, it can decrease compile times. Decreased compile times and an SSD, Gentoo should install in no time flat... |
