Newbie: Which partition is directory on?

| I hope this isn't a stupid question:
If I run df, I can see /, /boot, /home, etc, along with the amount of free
space. I can't however see /etc, /dev, /local, etc.
How do I tell how much room the partition with /etc has?

If you have /etc in its own partition then you "will" see it with 'df' i
susspect you dont have it mounted on its own partition that is not a
normal thing to do, not with /etc, possable yes, unlikly no.

du -m /etc
man du for more details.

/etc is on the / partition, apparently.
To see the disk space available for any directory:
cd <the directory> ; df .
is the easiest way. No need to fuss over seeing what is mounted where.
I suggest you do some reading on Unix, as this is a pretty basic
concept. My old favorite is:
The Unix programming Environment
by Brian W. Kernighan and Rob Pike.
Prentice Hall, Inc., 1984.
ISBN 0-13-937681-X (paperback), 0-13-937699-2 (hardback).
I used that when it first came out, maybe in an earlier edition ...
likely I am quite obsolete :-) I'll let others add their suggestions,
assuming you get any in between the flames -) If you search on Amazon or
google you will find many good modern books and on-line references.

The *nix filing tree starts with the root directory, aka '/', which is in a
specific partition (eg /dev/hda1). To access other partitions seamlessly,
*nix mounts (see: $ man 8 mount) them onto this filing tree at specific
directories. Thus, you may have partition '/dev/hda2' mounted at '/home'.
As *nix traces a file down this tree, it automatically jumps across the
partitions (or machines if the partition is on another machine!) as necessary.
So, not having a '/etc' partition tells you that it resides on (as part of)
another partiton. But which one? Trace back up its path directories until
you meet a known partition. In this case, the parent of '/etc' is '/',
which is a known partition. So '/etc' resides on the '/' partition.
eg for the file '/home/fred/bloggs', the parent of 'bloggs' is '/home/fred'
- not a partition, trace up... the parent of 'fred' is '/home' - a
partition. So '/home/fred/bloggs' resides on the '/home' partition.
If you want to know how much space the '/etc' tree is using of the '/'
partition, try the 'du' command:
#man du
DU(1) FSF DU(1)
NAME
du - estimate file space usage
SYNOPSIS
du [OPTION]... [FILE]...
DESCRIPTION
Summarize disk usage of each FILE, recursively for direc_-
tories.
....
# du -s /etc
6716
/etc

If it doesn't show up with df, it's not on its own partition.
Use:
df /etc /usr ...

| If you don't see /etc, /dev, /local, etc., and just see /boot, /home,
then all these partitions (wich you dont see in df) are under / (root),
so, the free space available for all of these is the free space in your
/ partition.

Another useful command if you want to know how much space a directory is
using is 'du -hs /directory_name"
Example:
# du -hs /etc/
17M /etc
The -s specificies a summary rather than listing each file individually, and
the -h specifies "human-readable" (i.e. translate from bits to K, M, or G as
appropriate).
Cheers,
Brian
