#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
[root@localhost ~]# 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
[root@localhost ~]# tail -1 /etc/bashrc export PYTHONSTARTUP="/usr/lib/python2.6/site-packages/tab.py"
#注销重新登陆
[root@localhost ~]# login
#测试
