小编use*_*151的帖子

我试图在我的Java程序中运行以下命令

Runtime.getRuntime().exec("ls -lrt service/logs/post/level2.log | awk '{print $9}'");
or
Runtime.getRuntime().exec("ls -lrt service/logs/post/level2* | awk '{print $9}'");

它给了我以下错误

ls: 0653-341 The file | does not exist.
ls: 0653-341 The file awk does not exist.
ls: 0653-341 The file '{print does not exist.
ls: 0653-341 The file $9}' does not exist.

请帮助我
