1. 先准备一个tab.py的脚本

  shell> cat tab.py

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

#!/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

2. 查看Python默认的模块存放地址

1 2 3 4 5 6 7

[root@localhost ~]# 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 Type "help", "copyright", "credits" or "license" for more information. >>> import sys >>> sys.path ['', '/usr/lib64/python26.zip', '/usr/lib64/python2.6', '/usr/lib64/python2.6/plat-linux2',

3. 拷贝该脚本到默认模块存放路径

1	cp tab.py  /usr/lib64/python2.6/

4. 现在可以用了
