Hi,
    Let's say there are many many sub-directories under the
current
directory, and all sub-dir is named like "sub00", "sub01",
"sub02",
etc., under each sub-dir there is an executable, a.out.

    What I want is a script or command, which can go to each
sub
directory and call a.out and re-direct the dump out from
a.out to a
file, something like

        cd sub00
        a.out > log

    I am not familiar with c-shell program, is such
command/script on
top of your mind?

Thanks.
