Don't know about tcsh but maybe this example can help a little :

Code:
# ls /opt/sfw/lib/*.so | head -2 >/tmp/input
# cat /tmp/input
/opt/sfw/lib/libFnlib.so
/opt/sfw/lib/libImlib.so
# while read line
> do
> echo "parsing1 = $line"
> echo "parsing2 = ${line##*/}"
> echo "parsing3 = $(basename $line)"
> echo "parsing4 = $(dirname $line)"
> echo "parsing5 = $(echo $line | sed 's|.*/||g')"
> done </tmp/input
parsing1 = /opt/sfw/lib/libFnlib.so
parsing2 = libFnlib.so
parsing3 = libFnlib.so
parsing4 = /opt/sfw/lib
parsing5 = libFnlib.so
parsing1 = /opt/sfw/lib/libImlib.so
parsing2 = libImlib.so
parsing3 = libImlib.so
parsing4 = /opt/sfw/lib
parsing5 = libImlib.so
#

Just feel free to test and adapt to your needs.

parsing 4 could also be written ${line%/*} (but i don't know whether tcsh handle it or not)

By the way, if you want to use sed in order to parse Path name that contains / you'd better go for a delimiter such as | or : instead of a / otherwise you would have to escape any / by a \ otherwise would be interpreted as a delimiter ...
