linux python tab补全

默认python是没有tab键补全功能的：

import tab
Traceback (most recent call last):
File “”, line 1, in
ImportError: No module named tab

创建tab.py文件

# vi tab.py

添加以下内容：

#!/usr/bin/python
# python tab 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

将tab.py文件拷贝到/usr/lib64/python2.7/

# cp tab.py  /usr/local/python/lib/python2.7
#chmod 755 /usr/local/python/lib/python2.7/tab.py、
