首先，要找到Python的路徑

[[email protected] python2.6]$ python
Python 2.6.6 (r266:84292, Nov 22 2013, 12:16:22) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.path
[‘‘, ‘/usr/lib64/python2.6‘, ‘/home/hfrznew/intedio/python‘, ‘/usr/lib64/python26.zip‘, ‘/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‘, ‘/usr/lib/python2.6/site-packages/setuptools-0.6c11-py2.6.egg-info‘]
>>>

切換到目錄/usr/lib64/python2.6新建文件vim tab.py

#!/usr/bin/env python
#python startup file
import sys
import readline
import rlcompleter
import atexit
import os
#tab comletion
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

然後就可以在命令行裏面用TAB鍵來補全了

>>> sys.

然後可以在.bashrc裏面加一個環境配置，

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

執行命令source .bashrc

然後就可以不用在引用就直接可以TAB啦
