hallo,

I have a little problem with bash

my a.out makes only printf(..., getpid(), getppid())

echo $$; ( a.out; v=1; )

results:

8093
27760 27759

8093 for PID of terminal-shell, 27759 for subshell
of '(...)' and 27760 for subshell of a.out.

What happens with:

echo $$; ( a.out; )

8093
27780 8093

one subshell "fails", why?

I have not found anything in man page.

Many thanks for help, Reiner
