vi python_tab.py

#!/usr/bin/env Python

import sys

import readline

import rlcompleter

import atexit

import os

#tab completion

readline.parse_and_bind('tab: complete')

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

将脚本复制到此目录下/usr/lib64/python2.6/

cp python_tab.py /usr/lib64/python2.6/

运行python，导入刚刚创建的脚本
