Question

Named pipes work fine, but you have a nicer, more direct syntax available via bash process substitution that has the added benefit of not using a permanent named pipe that must later be deleted (process substitution uses temporary named pipes behind the scenes):

foo -o >(other command)

Also, should you want to pipe the output to your command and also save the output to a file, you can do this:

foo -o >(tee output.txt) | other command
