tformat.py

#!/usr/bin/python
import time
import sys
import re


def tf(line):

  timestemp = re.findall(r'(16\d{8})\D', line)
  for x in timestemp:
      s_time = time.strftime("%Y-%m-%d %H:%M:%S",time.localtime(int(x)))
      line = line.replace(x,s_time)
  #s_time = time.strftime("%Y-%m-%d %H:%M:%S",time.localtime(seconds))
  print line.rstrip()
  return



if len(sys.argv)==1 :
    data = sys.stdin.readlines()
    for line in data:
        tf(line)
else :
    fp = open(sys.argv[1], "r")
    while True:
        line = fp.readline()
        if not line:
            break
        tf(line)

使用方法：

chmod a+x ./tformat.py
cat  file | ./tformat.py

或者

tformat.py file

另一种用法：
leon@ubuntu:~/work$ cat <<EOF | ./line.py
