我正在尝试使用Spur通过SSH连接到远程服务器。当我给出“ ps”和“ aux”参数时，它会很好地工作。当我输入“ ps”，“ aux”，“ |”，“ grep”和“ java”时，它给我一个错误

spur.results.RunProcessError: return code: 1

我的代码如下：

import spur

shell = spur.SshShell(hostname='hostname',

username='uname',

password='password')

with shell:

result = shell.run(['ps', 'aux', '| grep java'])

print result.output

如果有人遇到类似问题，请帮助我

解决方案

它应该通过执行以下操作：

import spur

shell = spur.SshShell(hostname='host',

username='user',

password='password')

with shell:

result = shell.run(['sh','-c','ps aux | grep java'])

print result.output

就我而言，结果是：

user 5090 0.0 0.0 9632 2472 ? Ss 04:06 0:00 sh -c ps aux | grep java

user 5093 0.0 0.0 9116 904 ? S 04:06 0:00 grep java
