Python shell 交互返回结果被截断

[chenshun00]

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 :）

改成 ps -efww

@keakon 因缺斯汀 ， 这个确实可以，请问下这个是由于什么原因 :)

-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
