OS X / Linux: pipe into two processes?

Question

I know about

program1 | program2

and

program1 | tee outputfile | program2

but is there a way to feed prog

Answer 1

Other answers introduce the concept. Here is an actual demonstration:

$ echo "Leeroy Jenkins" | tee >(md5sum > out1) >(sha1sum > out2) > out3

$ cat out1
11e001d91e4badcff8fe22aea05a7458  -

$ echo "Leeroy Jenkins" | md5sum
11e001d91e4badcff8fe22aea05a7458  -

$ cat out2
5ed25619ce04b421fab94f57438d6502c66851c1  -

$ echo "Leeroy Jenkins" | sha1sum
5ed25619ce04b421fab94f57438d6502c66851c1  -

$ cat out3
Leeroy Jenkins

Of course you can > /dev/null instead of out3.
