python tab补全

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

[root@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

[root@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

[root@CentOS_11 day01]# cat /etc/profile

export PYTHONSTARTUP=/root/scripts/python/day01/tab.py

3、加载全局变量生效

[root@CentOS_11 day01]# source /etc/profile

4、验证

[root@CentOS_11 day01]# python
Python 2.6.6 (r266:84292, Nov 22 2013, 12:16:22)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] on linux2

>>> a
