python 中的命令补全脚本

该命令补全脚本来自网络，把脚本放到特定的目录下，用的时候import进来就可以了

路径如下查找：

>>> os.sys.path

['', '/usr/lib64/python26.zip', '/usr/lib64/python2.6', '/usr/lib64/python2.6/plat-linux2', '/usr/lib64/python2.6/lib-tk', '/usr/lib64/python2.6/lib-old', '/usr/lib64/python2.6/lib-dynload', '/usr/lib64/python2.6/site-packages', '/usr/lib/python2.6/site-packages']

把脚本放到/usr/lib64/python2.6/site-packages下即可

补全脚本：tab.py

#!/usr/bin/env python

# python startup file

import sys

import readline

import rlcompleter

import os

readline.parse_and_bind('tab: complete')

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