Python shell 交互返回结果被截断

資深大佬 : chenshun00 63

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

[[email protected] ~]# 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 :）

@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
