java 调用其他应用程序时，可能在windows下没有问题，但是转到linux下，却会报这样那样的错误，比如有设计文件操作会报FileNotFoundException等等(如下代码)：

ProcessBuilder builder = new ProcessBuilder();
builder.command(ffmpeg -i /data/download_video/20160425/20160425235938929164582_1.flv -y -vcodec libx264 -vpre ultrafast -vpre baseline -cqp 28 -coder 0 -refs 3 -deblockalpha 1 -deblockbeta -1 -me_method umh -subq 9 -me_range 32 -trellis 2 -chromaoffset -2 -nr 0 -b_strategy 1 -bframebias 0 -directpred 3 -g 250 -i_qfactor 1.3 -b_qfactor 1.4 -flags2 +bpyramid+wpred+mixed_refs+8x8dct -acodec libfaac -s 640*360 -b 532000 -ab 58000 -r 15 -pass 1 /data/video/output/20160425/20160425235938929164582_1_06400360.mp4);
builder.start();

原因：不同的操作系统指令之间如果存在空格，可能会出现无法识别指令的错误。

解决方法：指令中有空格的需要用不同的字符串分开,将指令用空格进行split，通过数组方式进行指令传值，使用API：

public ProcessBuilder command(String... command)

可参考ProcessBuilder 类说明：

Constructs a process builder with the specified operating system program and arguments. This is a convenience constructor that sets the process builder's command to a string list containing the same strings as the command array, in the same order. It is not checked whether command corresponds to a valid operating system command.

Parameters:

command a string array containing the program and its arguments
