推荐答案

有没有做到这一点任何UNIX的一般方式。结果每个操作系统都有不同的方式来处理它，有些是很辛苦。你虽然提到Linux操作系统。对于Linux，该信息是在/ proc文件系统。结果要得到的进程id 9999在命令行中，读取文件的/ proc / 9999 / CMDLINE 。

There is not any general way to do this unix.
Each OS has different ways to handle it and some are very hard. You mention Linux though. With Linux, the info is in the /proc filesystem.
To get the command line for process id 9999, read the file /proc/9999/cmdline.
