How can I direct standard output into two pipes?

Question

I need to do two separate things with the standard output stream of my program: Say, direct it into two pipes, or print it to the terminal and direct it into a pipe. But - none of these things is directing it into a file.

If I wanted a pipe + a file, I would use the tee command: myprog | tee out.txt | another_command, as explained here. But what if none of the two actions are writing to a file?

You can use process substitution in bash to do that. Say you want to redirect output from myprog to two separate entities to read on, use the >(..) along with tee

myprog | tee >(prog1) >(prog2)

See Greg's Wiki or the man bash docs for more information.

@Inian; Indeed, the direct duplicates' answers are inferior to yours :-) – einpoklum Aug 28 '20 at 10:37
