Linux python <tab>自动补全

为Python添加交互模式下TAB自动补全以及命令历史功能。

1.获取python目录

[root@localhost ~]# python

Python 2.6.6 (r266:84292, Jul 23 2015, 15:22:56)

[GCC 4.4.7 20120313 (Red Hat 4.4.7-11)] on linux2

Type "help", "copyright", "credits" or "license" for more information.

>>> import sys

>>> sys.path

['', '/usr/lib/python2.6/site-packages/paramiko-1.7.7.1-py2.6.egg', '/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/lib64/python2.6/site-packages/gst-0.10', '/usr/lib64/python2.6/site-packages/gtk-2.0', '/usr/lib64/python2.6/site-packages/webkit-1.0', '/usr/lib/python2.6/site-packages', '/usr/lib/python2.6/site-packages/setuptools-0.6c11-py2.6.egg-info']

>>>

从上面看出python在我系统上的路径是 /usr/lib/python2.6/site-packages

2.切换至该目录写个tab.py的脚本,脚本目录就是处理python中<tab>事件，脚本内容如下

[root@localhost]# cd /usr/lib/python2.6/site-packages

[root@localhost python2.6/]# vim tab.py

#!/usr/bin/python

# python tab 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.切换至自己主目录

[root@localhost python2.6]# cd

[root@localhost  ~]# vim .bashrc

4. 增加环境变量

export PYTHONSTARTUP=/usr/lib/python2.6/site-packages/tab.py

5.配置环境变量生效

[root@localhost ~]# source .bashrc
