How to find directory size and disk free space:
1) command: du -sh /home/*
example:
tokunbo@debian7:~$ du -sh /home/*
40M /home/downloads
4.0K /home/web
20K /home/testuser
16G /home/tokunbo
tokunbo@debian7:~$
then to find details of directories under "/home/tokunbo":
command: du -sh /home/tokunbo/*
Just keep on adding the directories / subdirectories to know which file/s / DIR is eating up your diskspace. For example:
command: du -sh /home/tokunbo/subdir1/subdir2/subdir3/*
Another good command to bear in mind is:
command: df -h... outputs disk usage in human readable format, showing percntage used/available, etc
