一个很实用的Python脚本

开了好几个term，当前路径都一样，分不清咋办？

在.bashrc里执行term-title.py

#!/usr/bin/python
s = [
'黄山四千仞，三十二莲峰',
'会当凌绝顶，一览众山小',
'谁将依天剑，削出倚天峰',
'惟有南岳独如飞',
'人天北柱',
'长留一片月，挂在东溪松',
'没有木耳的黑木崖',
'穿过你的黑毛的我的手']
i = 0
F = '/tmp/term-title'
try:
  with open (F, 'rb') as f: i = int.from_bytes(f.read())
except Exception: pass
try:
  with open (F, 'wb') as f2: f2.write((i + 1).to_bytes())
except Exception: pass
print(f'\033]2;{s[i % len(s)]}\a')
