问我想通过管道将一个脚本的输出传递给不同的脚本，这些脚本将独立处理第一个脚本的输出。

#!/usr/bin/env bash
my_fifo=~/.my_ipc_fifo
mkfifo "$my_fifo" || exit
exec {out_to_fifo}>"$my_fifo" || exit

answer="n"
while [ "$answer" != 'y' ];do
    echo "enter the first value :"
    read first
    echo "the output is: "
    echo 6                          # one copy for the user
    printf '%s\0' 6 >&$out_to_fifo  # one copy for the other program
    echo "enter value of A:"
    read  A
    printf '%s\0' "$A" >&$out_to_fifo
    echo "do you want to exit"
    read answer
done

#!/usr/bin/env bash
my_fifo=~/.my_ipc_fifo
exec {in_from_fifo}<"$my_fifo" || exit  # note that the first one needs to be started first!

while IFS= read -r -d '' first <&"$in_from_fifo"; do
  echo "Read an input value from the other program of: $first"
  read -r -d '' second <&"$in_from_fifo"
  echo "Read another value of: $second"
  read -p "Asking the user, not the FIFO: Do you want to exit? " exit_answer
  case $exit_answer in [Yy]*) exit;; esac
done
