Redirecting output to a file via bash
本问题已经有最佳答案，请猛点这里访问。
我需要在MIPS和ARM处理器上运行一系列程序执行模拟，因为我正在使用一个名为MPSoCBench的基准测试。 总共将有200多个模拟，所以我创建了一个bash脚本来逐个执行它并将输出保存到文件中。 但是，出于某种原因，它不会像应该的那样重定向输出。
这是bash脚本：

例如，如果我运行：
终端输出是：

如果我尝试使用以下命令将此输出重定向到文件：
然后发生了一些奇怪的事情，首先还有终端输出：

就像有些线路被重定向而其他线路没有被重定向，这里发生了什么？ 也许多线程？ 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？
谢谢。
程序输出似乎是STDERR而不是STDOUT。 尝试一下：
1 | ./MPSoCBench -p=mips -s=dijkstra -i=noc.lt -n=2 -r > output/MIPS/dijkstra/dijkstra-2.out |
改变为
1 | ./MPSoCBench -p=mips -s=dijkstra -i=noc.lt -n=2 -r > output/MIPS/dijkstra/dijkstra-2.out 2>&1 |
请注意重定向后添加的
