1.获取 *** 作目录
[root@liu site-packages]# pythonPython 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', '/usr/lib64/python2.6/lib-tk', '/usr/lib64/python2.6/lib-old', '/usr/lib64/python2.6/lib-dynload', '/usr/lib64/python2.6/site-packages', '/usr/lib64/python2.6/site-packages/gtk-2.0', '/usr/lib/python2.6/site-packages']>>>123456789
可以看出,我的工作目录是/usr/lib/python2.6/site-packages/。
2.进入工作目录,编写tab.py补全文件
[root@liu site-packages]# cd /usr/lib/python2.6/site-packages/[root@liu site-packages]# vim tab.py 123
tab.py内容如下,建议粘贴的时候保证格式正确性
1 #!/usr/bin/python
2 # python tab file
3 import sys 4 import readline 5 import rlcompleter 6 import atexit 7 import os 8 # tab completion
9 readline.parse_and_bind('tab: complete') 10 # history file
11 histfile = os.path.join(os.environ['HOME'], '.pythonhistory') 12 try: 13 readline.read_history_file(histfile) 14 except IOError: 15 pass
16 atexit.register(readline.write_history_file, histfile) 17
18 del os, histfile, readline, rlcompleter123456789101112131415161718
3.添加环境变量,使其生效
[root@liu site-packages]# cd [root@liu ~]# vim .bashrc123
在末尾添加一行
export PYTHONSTARTUP=/usr/lib/python2.6/site-packages/tab.py1
4.重读.bashrc文件
source .bashrc1
或者
. .bashrc1
5.测试效果
[root@liu ~]# python

完成。我一开始一直报错,然后通过排查就是因为tab.py格式不正确。注意其格式。
1.只需输入文件或目录名的前几个字符,然后按TAB键,如无相重的,完整的文件名立即自动在命令行出现,如有相重的,再按一下TAB键,系统会列出当前目录下所有以这几个字符开头的名字
2. 在命令行下,只需输入例如m,再连续按两次TAB键,系统将列出所有以m开头的命令,(包括自定义的Bshell命令函数),对查找某些记不清楚的命令特有用。例如输入ftp,将查到ftp,ftpcount,ftpwho,ftpshut等本不熟悉的命令。
