问题ProcessBuilder运行脚本sh [英] Problem ProcessBuilder running script sh

问题描述

尝试使用以下代码执行脚本：

trying to execute an script, using this piece of code:

String command = "./myScript.sh";
pb = new ProcessBuilder(command, param1, param2);
pb.directory(directory);
pb.start();

我没有收到任何错误，但是没有出现假设的结果。无论如何，我尝试在终端中运行相同的命令，直接，并且一切正常。

我错过了什么？

I am not getting any kind of error, but neither the supposed results. Anyway, I tryed to run the same command, direclty in the terminal, and everything working correctly.
Am I missing something??

谢谢提前

推荐答案

问题不在于我调用脚本的方式，这是正确的。

但是它在剧本里面。起初它是：

The problem was not on the way I called the script, which was right.
But it was inside the script. At first it was:

#!/bin/bash
inputFolder=$1
outputFolder=$2 

cd $inputFolder

for file in `ls ` ; do
ffmpeg -i $inputFolder/$file -ar 22050 $outputFolder/$file.mp4 
done

但我找不到找不到ffmpeg命令，所以我将其更改为：

But I got ffmpeg command not found, so I changed it to:

#!/bin/bash
inputFolder=$1
outputFolder=$2 

cd $inputFolder

for file in `ls ` ; do
/usr/local/bin/ffmpeg -i $inputFolder/$file -ar 22050 $outputFolder/$file.mp4 
done  

带孔路径。但我仍然怀疑，为什么这是必要的，如果我在我的路径中有ffmpeg并且我在控制台直接执行任何目录？
如果有人可以给我一个答案，欢迎提供：）

with the hole path. But I have still doubts, why this is necessary, if I have ffmpeg in my path and I cand execute in console direclty form any directory?? If someone can give me an answer, it will be welcome :)
