The output of a command is this

/opt/kirkby/gcc-4.4.2/lib/libgcc_s.so.1

how can I strip off the path, and so just get the 'libgcc_s.so.1' ?

I guess I need to strip from the first character, to the last '/', but are not
sure how to do this.

$ var="/opt/kirkby/gcc-4.4.2/lib/libgcc_s.so.1"
$ echo "$var"
/opt/kirkby/gcc-4.4.2/lib/libgcc_s.so.1
$ echo "${var##*/}"
libgcc_s.so.1

Apart from the command 'basename' which is tailor-made for this task,
you could do this too:

out='/opt/kirkby/gcc-4.4.2/lib/libgcc_s.so.1'
savIFS=$IFS IFS='/'
set -f
set x $out; shift
for var
do
:
done
IFS=$savIFS
printf '%s\n' "$var"

## or you could simply do:
printf '%s\n' "$out" | sed -e 's|.*/||'

As is POSIX parameter expansion.
