How to find (as grouped) the directory who is taking all the disk spaces?

# df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/vda1        60G   54G  6.4G  90% /
devtmpfs        1.4G     0  1.4G   0% /dev
tmpfs           1.4G     0  1.4G   0% /dev/shm
tmpfs           1.4G  161M  1.3G  12% /run
tmpfs           1.4G     0  1.4G   0% /sys/fs/cgroup
tmpfs           285M     0  285M   0% /run/user/0

It does not help to see /dev/vda1 is 90%, how to check which directories having the largest disk reserve?

example:

/var/log/httpd    20GB
/var/log/pluto    10GB
/var/log/syslog    5GB
/var/log/tcpdump   1GB
/...              restGB
  • Try this sudo du -hca --time / | grep -E "^[0-9\.]*[G]" . Read here for extra info: https://askubuntu.com/a/1167390/968501 – Raffa Oct 04 '19 at 02:11

In addition to the above, files that are open(2)ed for write will take up diskspace. I use bigopenfiles to see them.

alias bigopenfiles='sudo lsof / | awk '\''{if($7 > 1048576) print $7/1048576 "MB" " " $9 }'\'' | sort -n -u'

Other "invisible" files are those which programs open(2) O_TMPFILE option, or have been opened and unlink(2)ed.

alias deletedfiles='sudo lsof / | egrep '\''PID|\(deleted\)'\'''

For example,

walt@bat:~(0)$ bigopenfiles
lsof: WARNING: can't stat() fuse.gvfsd-fuse file system /run/user/1000/gvfs
