#需求

为了方便工作，我们需要在Python终端下添加Tab健补全功能

 

#存放脚本路径

Pyhton2.6

/usr/lib/python2.6/site-packages/

Python2.7

/usr/lib/python2.7/dist-packages/

 

 

#脚本代码

[[email protected] ~]# cat /usr/lib/python2.6/site-packages/tab.py
try:
    import readline
except ImportError:
    print("Module readline not available.")
else:
    import rlcompleter
    readline.parse_and_bind("tab: complete")

 

#bashrc文件配置

[[email protected] ~]# tail -1 /etc/bashrc
export PYTHONSTARTUP="/usr/lib/python2.6/site-packages/tab.py"

 

#注销重新登陆

[[email protected] ~]# login

 

#测试
