I followed Camaleón's suggestion, the output of

cd /
du -h | grep "[0-9]M" | sort -n -r | less

the first few ones even reached hundreds of M.

Are those big figures for files or folders?


folders.



636M ./src/some_software
592M ./src/some_software/
543M ./.local/share
543M ./.local
540M ./.local/share/Trash/files
540M ./.local/share/Trash
494M ./Documents/p
392M ./Documents/c
375M ./Documents/c/BS409
356M ./src/some_software/software/test
356M ./.mozilla/firefox/3gbs90vf.default
356M ./.mozilla/firefox
356M ./.mozilla

Then it's fine. I would worry when a file gets oversized, that may
indicate a problem.

But I would carefully watch your "/.local/share/Trash" and your Firefox
profile. Both folders look very big to me, you may have there "erasable"
files (deleted and/or cached files you can safely remove).

Look:

sm01@stt008:~$ du -hs .local/share/Trash .mozilla
104M .local/share/Trash
120M .mozilla


I just made a clean. now better. Thanks ^_^ for your time.



the output of du -h is 34G

Tip: "du -sh" to get the summary the output, but it will be also
interesting to know what's the result of "df -h" to get the whole
picture of your system space.


# df -h

(...)

Overall looks good.

Sorry I still don't know which files took the partition which /
mounted.


are there some easy way to see which files sit on which partition?

You can also use "df" for files, it will print the partition on what
they're are mounted. For example:

sm01@stt008:~$ LANG=POSIX; df -h /data/backup/sm01/2010-09-12.tar.bz2
.mozilla
Filesystem Size Used Avail Use% Mounted on
/dev/sdb1 459G 401G 35G 93% /data/backup
/dev/sda3 115G 22G 94G 19% /


The command #LANG=POSIX; df -h * is cool. Thanks,

Question 1: still missing few MB, which I don't know being occupied by which
files. welcome providing guess. and there is none invisible file in /. is it
reasonable for below files?

/# LANG=POSIX; df -h /lib
Filesystem Size Used Avail Use% Mounted on
/dev/sda5 658M 377M 248M 61% /

330M /lib
12M /etc/
6.7M /bin
5.7M sbin/
4.6M /lib32
1.3M /root/

200K srv/
4.0K selinux/
4.0K lib64/
16K lost+found/
8.0K media/
8.0K mnt/

Question 2: is it normal?

# LANG=POSIX; df -h sys/
Filesystem Size Used Avail Use% Mounted on
sysfs 0 0 0 - /sys

I don't have /sys partition.

Thanks,
