針對配置文件進行切分，重組，每隔30行為一段，進行重新生成功能。
代碼如下
#!/usr/local/python/bin/python
# coding=utf-8
import sys
import re
import os
f = open('config.conf','r')
#判斷文件條數
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 '文件總條數：' + str(file_num)
i = 0 #設置計數器
while i < file_num : #表示文件行數
with open('/tmp/newfile/newfile'+str(i),'w') as f1:
for j in range(0,30) : #這裡設置每個子文件的大小
if i <= file_num : #這裡判斷是否已結束，否則最後可能報錯
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) + " begin
")
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) + " end
")
f2.writelines("
")
num = num + 1
eachFile(filepath1) 腳本說明：
目錄路徑：/tmp
配置文件：config.conf
準備目錄：/tmp/newfile/
最終新的配置文件為：check.py
