python的tab补全脚本

#!/usr/bin/env python

import sys

import readline

import rlcompleter

import atexit

import os

# tab completion

readline.parse_and_bind('tab: complete')

# history file

histfile = os.path.join(os.environ['HOME'], '.pythonhistory')

try:

    readline.read_history_file(histfile)

except IOError:

    pass

atexit.register(readline.write_history_file, histfile)

del os, histfile, readline, rlcompleter

为了日后的方便我们把这个脚本放到python的搜索目录中去

/usr/lib/python2.4/site-packages 这个时候不管我们在什么目录运行python目录 都能引入tab模块
