How to force delay in command execution in unamed pipe?

[Peng Yu]

Hi

cmd <(cmd1) <(cmd2)

For a command like the above, I will need to let cmd2 run after cmd1
finishes. Of course, one could use temp files like the following. But
is there a way to follow such a constraint with unnamed pipes?

cmd1 > file1
cmd2 > file2
cmd file1 file2

Another way to avoid using unnamed pipes is to use a pipeline with
redirection like this. Is there a way to force cmd2 to run only after
cmd1 finishes in this pattern?

cmd1 | {
cmd2 | {
cmd "$fd1" "$fd2"
} {fd2}<&0
} {fd1}<&0
