Python命令行自动补全

1. 设置"PYTHONSTARTUP"环境变量

 

cadenwu@cadenwu:~$ cat .bashrc
...
# setting python env
PYTHONSTARTUP='/home/cadenwu/.pythonstartup'
export PYTHONSTARTUP

2. 添加.pythonstartup文件

cadenwu@cadenwu:~$ cat .pythonstartup
try:
    import readline
except ImportError:
    print " readline not available"
else:
    import rlcompleter
    readline.parse_and_bind("tab: complete")
