Files used by mount

Question

/dev/md1 6068992 5204648 551080 91% /

I have 91% taken and am trying to discover what files are taking up space. I'm using linux. Does any one know the command?

thanks

Answer 1

du -k -S -x / | sort -n -r | head -10

Will return the 10 largest files on the root file system.

Edit: @Alnitak's answer included the -S and -x, included here for completeness.

Answer 2

This will list the directories in (reverse) order of size

# du -k -S -x / | sort -r -n

Note:

• -S tells it not to include subdirectory counts, so each directory figure will be the use of that directory, not the tree below it
• -x tells it not to leave that file system. Without this it'll go into /proc, /dev, /sys, etc, and you don't need to du those.

EDIT: doh! didn't mean the --max-depth=1 - just force of habit!

Answer 3

You can use find to locate the largest files on your system, for example:

find / -size 100M -print

Will find and print the names of all files that are 100 MB or larger. You can use the -mount option if you only want to look in the partition that the specified directory resides on:

find / -mount -size 100M -print

Answer 4

I usually use:

du -x / | sort -ns

But when on the GUI you can also use filelight or fsview.

Answer 5

This seems like a dupe of Tracking down where disk space has gone on Linux?

Answer 6

Often it is not the size of a single file but what is contained in the subdirectories. I usually use the --max-depth=1 option to du to find the "big directories" in my home. Everything outside of home is installed in some way, so I can go to my package manager and let it show all installed packages, sorted by disk size; then I can throw out some things I do not need anymore.
