difflib模块对比apache配置文件差异

我们可以同下面的代码对所有的配置文件进行差异的html输出.

[root@www difflib]# cat  diff_conf.py 

#!/usr/bin/python  

import difflib  

import sys  

 

try:  

    textfile1=sys.argv[1]       #第一个配置文件路径

    textfile2=sys.argv[2]       #第二个配置文件参数

except Exception,e:  

    print "Error:"+str(e)  

    print "Usage: simple3.py filename1 filename2"  

    sys.exit()  

 

def readfile(filename):    

    try:  

        fileHandle = open (filename, 'rb' )  

        text=fileHandle.read().splitlines()      

        fileHandle.close()  

        return text  

    except IOError as error:  

       print('Read file Error:'+str(error))  

       sys.exit()  

 

if textfile1=="" or textfile2=="":  

    print "Usage: simple3.py filename1 filename2"  

    sys.exit()  

 

text1_lines = readfile(textfile1)    

text2_lines = readfile(textfile2)  

 

d = difflib.HtmlDiff()    

print d.make_file(text1_lines, text2_lines)   

[root@www difflib]# 

测试:

[root@www difflib]# python diff_conf.py /etc/httpd/conf/httpd.conf /etc/httpd/conf/httpd.confv2 >diff_con.html

然后你打开网页看一下,ok!
