Situation

File space is low

Trouble shoot disk hog

Resolution

The following command will list files/folders that are at least 1 GB in size in ascending order:

 

 sudo time du -ah / | uniq | grep "^[0-9]*[G]" | sort -g

 

The output will be similar to this:

 

user@server1:~> sudo time du -ah / | uniq | grep "^[0-9]*[G]" | sort -g       

du: cannot access '/proc/24299/task/24299/fd/3': No such file or directory

du: cannot access '/proc/24299/task/24299/fdinfo/3': No such file or directory

du: cannot access '/proc/24299/fd/4': No such file or directory

du: cannot access '/proc/24299/fdinfo/4': No such file or directory

If you need to refine your search you can list files in MB by changing the grep section as shown

 

 sudo time du -ah / | uniq | grep "^[0-9]*[M]" | sort -g

 

This will return far more hits:
