通过bash将输出重定向到文件

我需要在MIPS和ARM处理器上运行一系列程序执行模拟，为此我使用了一个名为。总共将有200多个模拟，所以我创建了一个bash脚本来逐个执行，并将输出保存到一个文件中。然而，由于某些原因，它没有像应该的那样重定向输出

下面是bash脚本：

source env.sh
echo "Simulation start"

echo "Simulation end"

例如，如果我运行：./MPSoCBench-p=mips-s=susansmoothing-I=noc.lt-n=1-r

终端输出为：

[['mips'], ['1'], ['susansmoothing'], ['noc.lt']]
./platform.noc.lt.x susansmoothing.mips.x 1

如果我尝试使用命令将此输出重定向到文件：./MPSoCBench-p=mips-s=susansmoothing-I=noc.lt-n=1-r>output/mips/susansmoothing/susansmoothing-1

然后一些奇怪的事情发生了，首先还是终端输出：

就像有些线路被重定向了，而另一些线路没有，这是怎么回事？也许是多线程？如果是这样，我如何等待程序完成执行，然后将终端输出复制到文件中

---

谢谢。

程序输出似乎在STDERR上而不是STDOUT上。尝试一下：

./MPSoCBench -p=mips -s=dijkstra -i=noc.lt -n=2 -r > output/MIPS/dijkstra/dijkstra-2.out

更改为

./MPSoCBench -p=mips -s=dijkstra -i=noc.lt -n=2 -r > output/MIPS/dijkstra/dijkstra-2.out 2>&1

---

注意重定向后添加的2>&1。它发送STDERR->STDOUT。

您可能没有在STDERR上进行管道输出。尝试使用&>而不是>bash4+。这与stderr无关，我只是尝试了一下，结果是一样的。也许这与多线程有关。出于某种原因，Tripp提出的解决方案不起作用，但使用&>did，@hnefatl可以将其作为答案发布吗？顺便说一句，这似乎需要了解ARM MIPS中的p；为Strings搜索dijkstra sha…等；在1,2,3,4中n的do；do./MPSoCBench-p=$p-s=$s-i=noc.lt-n=$n-r>output/$p/$s/$s-$n.out；完成；完成；完成
