Question

我是python的新手。

想知道如何逐行将Solaris11命令的输出转换为变量。目的是一次提取一行输出。

Solaris 11命令pkg list | pkg info，提供服务器上所有已安装软件包的详细列表。我只对提取名称，描述，版本，大小感兴趣。

到目前为止，我有以下代码：

#! /usr/bin/python

import os
import commands

'''
PCI package compliance

The purpose of this program is to pull package information from
Solaris11 and place that information into a comma separated file that can be read by excel.
the information in question is Name, Description, Version, size
'''

pkg_list = commands.getoutput('pkg list | pkg info')

pkgname = pkg_list[0]

print pkgname

然而，pkgname = pkg_list [0]并没有给我以name开头的整行。 pkgname = pkg_list [10]将只打印N.所以我相信我的问题是弄清楚如何格式化输入，这样我就可以输出每个记录4个字段。

根据要求，以下是“pkg list | pkg info”命令的一些示例输出。

       Name: x11/xmag
       Summary: xmag - magnify parts of the screen
   Description: The xmag program allows you to capture a static image of a
                portion of an X screen, and display it magnified.

更新：以下命令：

print pkg_list.split('\n')[0]+","+pkg_list.split('\n')[1]+','+pkg_list.split('\n')[4]+','+pkg_list.split('\n')[5]

产生输出：

Name: archiver/gnu-tar,       Summary: GNU version of the tar archiving utility,      Category: Development/GNU,         State: Installed

现在我需要遍历这些项目。有什么建议吗？

好吧，我快到了。以下代码循环遍历系统上的所有包：

#! /usr/bin/python


import os 
import commands

'''
PCI package compliance

The purpose of this program is to pull package information from
Solaris11 and place that information into a comma separated file that can be read by excel.
the information in question is Name, Description, Version, size
'''




for list in (commands.getoutput('pkg list | awk -F" " \'{print $1}\'').split('\n')):
        #command1 = "pkg info "+list
        pkg_list = commands.getoutput("pkg info %s" %list)
        print pkg_list.split('\n')[0]+","+pkg_list.split('\n')[1]+','+pkg_list.split('\n')[2] #+','+pkg_list.split('\n')[5]

提供以下输出：

Name: compress/pixz,       Summary: parallel indexing version of XZ,   Description: pixz compresses and decompresses files using multiple

然而，我不得不砍下最后一块，即元素[5]。添加代码后，我收到错误：

Traceback (most recent call last):
  File "/root/Documents/python/pci3", line 22, in <module>
    ver = pkg_list.split('\n')[5]
IndexError: list index out of range

有关如何获取最终元素的任何建议？

我能够从输出中删除空格。见下文。但是，我仍然需要打印最后一个元素即元素5（＃+ pkg_list.split（'\ n'）[5]）

#! /usr/bin/python


import os 
import commands

'''
PCI package compliance

Solaris11 and place that information into a comma separated file that can be read by excel.

for list in (commands.getoutput('pkg list | awk -F" " \'{print $1}\'').split('\n')):
        #command1 = "pkg info "+list
        pkg_list = commands.getoutput("pkg info %s" %list)
        #print pkg_list.split('\n')[0]+","+pkg_list.split('\n')[1]+','+pkg_list.split('\n')[2] #+','+pkg_list.split('\n')[5]
        output = []
        output = pkg_list.split('\n')[0]+","+pkg_list.split('\n')[1]+','+pkg_list.split('\n')[2]
        print output.replace(" ","")
