人有偏见 说什么都无用 本来不想理你

或者 mpirun 加上一个参数--stdin none
会导向 stdin 的程序 有点恶心 不太好用

#!/bin/bash
while read -r line
do
echo $line
(mpirun -np 1 ~/bin/test & wait) &
sleep 1
done < tasklist.txt
wait
echo "end..............."

打错

#!/bin/bash
while read -r line
do
echo $line
(mpirun -np 1 ~/bin/test &) &
sleep 1
done < tasklist.txt
wait
echo "end..............."
