Free Space

I am using FreeBSD and would like to know exactly how much free space I have on my hard drive at any given time. If I do a DF, this is what I get:

/dev/ad0s1a 49583 27912 17705 61% /
/dev/ad0s1f 3877828 248293 3319309 7% /usr
/dev/ad0s1e 19815 1618 16612 9% /var
procfs 4 4 0 100% /proc

Is this in Bytes? I believe I have a 4 GIG or a 3 GIG Drive in this machine. Is there a way to tell how much free space in MB I have left? Kinda like windows chkdsk?

I would also like to know if there is a way I can specify a username not to go back in a folder. For instance, If I setup username blah on my server, Is there a way I can tell ONLY that user has access ONLY to the /usr/home/blah folder and nothing below that subdirectory?

Not bytes, 1-K blocks (i.e. a kilobyte). So yor root directory (/) has 17.7 meg free and your /usr directory has 3.3 gig free. If that was my system I would want a lot more space in / (especially sence /home and /tmp are not seperate partitions) and less in /usr.

Here is a DF from my machine with the heading from DF included. As you can see, the third column is the one that tells you the amount of free (Available) space.

Filesystem 1k-blocks Used Available Use% Mounted on
/dev/hda8 497829 335615 136512 72% /
/dev/hda5 23302 8342 13757 38% /boot
/dev/hda1 2028098 1301788 621488 68% /home
/dev/hda7 6040288 4296264 1437188 75% /usr

If you type the following at a prompt, it will give you total available free space in KB:

df | awk '{n=n+$4} END {print n}'

and if you type this it will give you the answer in MB:

df -m | awk '{n=n+$4} END {print n}'

Hmmm...that was ugly scripting - it would be marginally better as:

df | awk '{n=n+$4} END {print n}'

for KB output

and

df -m | awk '{n=n+$4} END {print n}'

;)

Shoot me now.

Third time lucky:

df | awk '{n+=$4} END {print n}'

for KB, and

df -m | awk '{n+=$4} END {print n}'
