1.获取python目录【我使用的是64位ubuntu系统】
[~$]python
Python 2.7.3 (default, Apr 102013, 06:20:15)
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits"or"license"for more information.
>>> import sys
>>> sys.path
[‘‘, ‘/usr/lib/python2.7‘, ‘/usr/lib/python2.7/plat-linux2‘, ‘/usr/lib/python2.7/lib-tk‘, ‘/usr/lib/python2.7/lib-old‘,
‘/usr/lib/python2.7/lib-dynload‘, ‘/usr/local/lib/python2.7/dist-packages‘, ‘/usr/lib/python2.7/dist-packages‘,
‘/usr/lib/python2.7/dist-packages/PIL‘, ‘/usr/lib/python2.7/dist-packages/gst-0.10‘, ‘/usr/lib/python2.7/dist-packages/gtk-2.0‘,
‘/usr/lib/python2.7/dist-packages/ubuntu-sso-client‘, ‘/usr/lib/python2.7/dist-packages/ubuntuone-client‘,
‘/usr/lib/python2.7/dist-packages/ubuntuone-control-panel‘, ‘/usr/lib/python2.7/dist-packages/ubuntuone-couch‘,
‘/usr/lib/python2.7/dist-packages/ubuntuone-installer‘, ‘/usr/lib/python2.7/dist-packages/ubuntuone-storage-protocol‘]
>>>
从上面看出python在我电脑上的路径是 /usr/lib/python2.7
2.切换至该目录写个tab.py的脚本,脚本目录就是处理python中<tab>事件，脚本内容如下：
#!/usr/bin/python
# python startup file
import sys
import readline
import rlcompleter
import atexit
import os
# tab completion
readline.parse_and_bind(‘tab: complete‘)
# history file
histfile = os.path.join(os.environ[‘HOME‘], ‘.pythonhistory‘)
try:
readline.read_history_file(histfile)
except IOError:
pass
atexit.register(readline.write_history_file, histfile)
del os, histfile, readline, rlcompleter
3.切换至自己主目录
[/usr/lib/python2.7$]cd
[~$]vi .bashrc
4. 增加环境变量
#for python
export PYTHONSTARTUP=/usr/lib/python2.7/startup.py
5.配置环境变量生效
[~$]source .bashrc
