How does one find which files are taking up 80% of the space on a Linux webserver?
Solution 1:
Surely there are more elaborate ways, but the one I remember is
du --max-depth=1 -h /
Now take the directory that uses up most space (du --max-depth=1 -h /yourdir)
and go deeper until you find your culprit.
If want your output sorted by size and don't care for the human-readable format, you could also do du --max-depth=1 /your_dir | sort -n
Solution 2:
I find ncdu (http://dev.yorhel.nl/ncdu) to be quite helpful for this.
Solution 3:
I use the Gnome program baobab. You can run this on your desktop and t can connect via SSH to the server. It shows an easy to read graphical map of disk space usage. It's installed under Gnome as "Disk Usage Analyzer"
Solution 4:
Give gt5 a try.
Solution 5:
df -k shows which fs are the problem. Then cd to the top level dir for it and run du -xk | sort -n | tail -25 this will show the top 25 dir, sorted, for sun 9 or earlier, replace the x with a d.
