[bash] cutting text with sed


I'm looking for a way to cut of some text.
With the commando 'pwd' I list the current directory. (example: /home/cs/server05)

With these to lines:

SPATH="$(cd $(dirname $0);pwd)" ## /home/cs/server05
SNAME=`echo $SPATH | cut -f 4 -d/` ## server05

I'm able to read the full directory and cut of the last 8 values (static, always 8 characters).

The next problem is that I want to read what's between /home/ and the /server05. This value is dynamic by name and length. I tried using sed but the commando below gives me "cs/server05".

SERVER=`echo $SPATH | sed -e s/\.home\.\/''/`

What do I need to change to get 'cs' ?

cut -d/ -f3

Or is it more complex than that and you really need sed?

First you can also get SNAME with:
SNAME=`basename $SPATH`

for SERVER, you could try:
SERVER=`echo $SPATH | sed -r 's#(.*)/(.*)/(.*)#\2#'`

[edit]
Ok, it seems you find a better way
