python tab补全

liuming794

　　一、python tab补全
　　前提：tab补全先检查readline包是否安装，未安装通过yum安装即可
　　[iyunv@CentOS_11 day01]# rpm -qa |grep readline
readline-6.0-4.el6.x86_64
　　
　　1、可在任意目录下编辑脚本如下
　　[iyunv@CentOS_11 day01]# cat tab.py
# 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
　　
　　2、加入全局变量
　　[iyunv@CentOS_11 day01]# cat /etc/profile
　　export PYTHONSTARTUP=/root/scripts/python/day01/tab.py
　　
　　3、加载全局变量生效
　　[iyunv@CentOS_11 day01]# source /etc/profile
　　
　　4、验证
　　[iyunv@CentOS_11 day01]# python
