1、查看python模块存放的路径。

python

import sys

>>> 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

看到我的模块路径为/usr/lib64/python2.6.

2.到/usr/lib64/python2.6路径下面去创建补全文件。

cd /usr/lib64/python2.6

vi startup.py

#!/usr/bin/python

# python startup file

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

3、编辑/etc/bashrc

vi /etc/bashrc

export PYTHONSTARTUP=/usr/lib64/python2.6/startup.py

4、source /etc/bashrc
