Bash: how do I pipe stdout and stderr of one process to two different processes? -

-

i have process myprocess1 produces both stdout , stderr outputs. want pipe 2 output streams 2 different downstream processes, myprocess2 , myprocess3, massage data , dump results 2 different files. possible single command? if not, 2nd best running 2 separate commands, 1 process stdout, other stderr. in case, first run be:

myprocess1 | myprocess2 > results-out.txt

what similar command process stderr? thx

without fancy games should work:

{ myprocess1 | myprocess2 > results-out.txt; } 2>&1 | myprocess3 > results-err.txt

with fancy games (which not work in /bin/sh, etc.) this:

myprocess1 2> >(myprocess3 > results-err.txt) | myprocess2 > results-out.txt
