File Size

[Kevin Daines]

I'm trying to find the answer to why my root volume has grown by about 38Mb. However the find command:

find . -size 30000000c

returns no values, am i doing something wrong?

Hi Kevin,

Here a command to see all the large files/dirs in a filesystem

du -akx / | sort -rn | more

I suspect there are no files in / that are *exactly* 30000000 bytes in size. The command will only find files that size.

Another thing to watch for.

If a filesystem was unmoutned and files were copied in and then its mounted. The files are invisible but still take up space.

Example

/steve is a fs and its unmounted.
copy in 20 MB
mount /steve

You can't see the files but they take up space.

If the prior post doesn't help, you may want to poke around with folders umounted. /var can only be done in single user mode.

Try,

find / -size +30000000

Kevin,

you need a +3000000.

NB: the du command mentioned above could potentially take a really long time to run if (as I do) you make / the entire disk.

Hi pcross,

Check that command again.

The -x will restrict it to *that* filesystem only.
It's really about the only why to poperly run the du command in an FS that has other filesystems mounted into it IF you're looking for space hogs.

Uhhmmm - OK - I just reread your post.

Why in the world would you make / the _entire_ disk?
