python命令行自动补全

~$ cat .pythonstartup
import os
import readline
import rlcompleter
import atexit

#tab completion
readline.parse_and_bind("tab: complete")

#history file
history_file = os.path.join(os.environ["HOME"],".pythonhistory")
try:
readline.read_history_file(history_file)
except IOError:
pass
atexit.register(readline.write_history_file,history_file)

del os,history_file,readline,rlcompleter

.bashrc中追加export PYTHONSTARTUP="~/.pythonstartup"source .bashrc使之生效这样Python命令行就支持自动补全和记录历史命令的功能了
