这是一个创建于 1829 天前的主题，其中的信息可能已经有所发展或是发生改变。
代码如下:
proc = subprocess.Popen(['ps -ef |grep java |grep -v grep'], stdout=subprocess.PIPE, shell=True)
proc.communicate()
retcode = proc.returncode
返回结果
root 1494 1 0 12 月 05 ? 00:04:51 java -jar -Dxxx=xx -Dxxx1=xx -Dxxx2=xx -Dxxx3=xx -Dxxx4=xx -Dxxx4222d
预期在 bash 上执行结果如下
[root@iZbp11om21c05wzu8e4tx0Z ~]# ps -ef |grep java |grep -v grep
root 1494 1 0 12 月 05 ? 00:04:51 java -jar -Dxxx=xx -Dxxx1=xx -Dxxx2=xx -Dxxx3=xx -Dxxx4=xx -Dxxx4222dsdfsdfsdfsdfsfdsfsdfsdfsdfsdfsdfsdfsdf=1 -Dxxx4222dsdfsdfsdfsdfsfdsfsdfsdfsdfsdfsdfsdfsdfx=1 -Dxxx4222dsdfsdfsdfsdfsfdsfsdfsdfsdfsdfsdfsdfsdt=1 -Dxxx4222dsdfsdfsdfsdfsfdsfsdfsdfsdfsdfsdfsdfsdfh=2 demo-0.0.1-SNAPSHOT.jar

-w Wide output. Use this option twice for unlimited width.
If ps can not determine display width, as when output is redirected (piped) into a file or another command, the output width is undefined (it may be 80, unlimited, determined by the TERM variable, and so on). The COLUMNS environment variable or --cols option may be used to exactly determine the width in this case. The w or -w option may be also be used to adjust width. |

bash 有.profile 等环境加载
然后非交互式 shell 和交互式 shell 了解一下，编程开发的非交互式不加载环境 |
