Are you refering to shell redirection?
>From the bash man pages ...
In the following descriptions, if the file descriptor num-
ber is omitted, and the first character of the redirection
operator is <, the redirection refers to the standard
input (file descriptor 0). If the first character of the
redirection operator is >, the redirection refers to the
standard output (file descriptor 1).
The word following the redirection operator in the follow-
ing descriptions, unless otherwise noted, is subjected to
brace expansion, tilde expansion, parameter expansion,
command substitution, arithmetic expansion, quote removal,
pathname expansion, and word splitting. If it expands to
more than one word, bash reports an error.
Note that the order of redirections is significant. For
example, the command
ls > dirlist 2>&1
directs both standard output and standard error to the
file dirlist, while the command
ls 2>&1 > dirlist
directs only the standard output to file dirlist, because
the standard error was duplicated as standard output
before the standard output was redirected to dirlist.

Subject: piping stderr and stdout to 2 different apps
is there a [simple | non-simple way to pipe the stderr of one
application
to the stdin of the next? i want this to work on standard libs, so I
can't just recompile the application generating the stderr.
if possible, i would like stdout to go to another pipe.
thanx,
will
