下面是如何实现PythonTab补全和历史命令管理方法。

Python的startup文件

为readline添加tab键自动补全功能，像shell一样管理历史命令

  • 获取python安装目录

>>> import sys
>>> sys.path
['', '/usr/lib64/python27.zip', '/usr/lib64/python2.7', '/usr/lib64/python2.7/plat-linux2', '/usr/lib64/python2.7/lib-tk', '/usr/lib64/python2.7/lib-old', '/usr/lib64/python2.7/lib-dynload', '/usr/lib64/python2.7/site-packages', '/usr/lib64/python2.7/site-packages/gtk-2.0', '/usr/lib/python2.7/site-packages']

安装目录为’/usr/lib64/python2.7’

  • 切换目录编写startup.py脚本,cp startup.py /usr/lib64/python2.7/

#!/usr/bin/env python

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
