    这是一个创建于 2132 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 

    请问下这个是什么问题导致的 :)

    -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
