Doh! Forgot about the extra parameters to instr (like the negative value for where to start searching!). Thanks anyway and sorry about the wasted bandwith. For those interested, here's the answer;

select '/dir1/dir2/test/file.out' filenm, substr('/dir1/dir2/test/file.out',
instr('/dir1/dir2/test/file.out','/',-1),length('/dir1/dir2/test/file.out')) shortnm
from dual;

FILENM                   SHORTNM
------------------------ --------

/dir1/dir2/test/file.out file.out
