针对配置文件进行切分，重组，每隔30行为一段，进行重新生成功能。
代码如下
#!/usr/local/python/bin/python
# coding=utf-8
import sys
import re
import os
f = open('config.conf','r')
#判断文件条数
def file_num(filename):
num_col = 0
with open(filename,'rb') as Fnum:
while(Fnum.readline() !=''):
num_col = num_col + 1
return num_col
file_num = file_num('config.conf')
print '文件总条数：' + str(file_num)
i = 0 #设置计数器
while i < file_num : #表示文件行数
with open('/tmp/newfile/newfile'+str(i),'w') as f1:
for j in range(0,30) : #这里设置每个子文件的大小
if i <= file_num : #这里判断是否已结束，否则最后可能报错
f1.writelines(f.readline())
i = i+1
else:
break
filepath1='/tmp/newfile/'
def eachFile(filepath):
num = 1
pathDir = sorted(os.listdir(filepath))
for allDir in pathDir:
child = os.path.join('%s%s' % (filepath, allDir))
file_name = child.decode('gbk')
print file_name
with open('/tmp/check.py','a+') as f2:
fopen = open(file_name, 'r+')
f2.writelines("# config.py sql" + str(num) + " beginn")
count=0
for line in fopen.readlines():
if count == 0:
f2.writelines(line)
count= count+1
else:
f2.writelines("UNION ALL " + line)
f2.writelines("# config.py sql" + str(num) + " endn")
f2.writelines("n")
num = num + 1
eachFile(filepath1)
脚本说明：
目录路径：/tmp
配置文件：config.conf
准备目录：/tmp/newfile/
最终新的配置文件为：check.py
