读取.bash_history的脚本

如果.bash_history中 包含timestamp，将很难阅读，下面Python 3脚本可翻译.bash_history

#! /usr/bin/env python3

import re
import sys
import time

if __name__ == '__main__':
    pattern = re.compile(br'^#(\d+)$')
    out = sys.stdout.buffer
    for pathname in sys.argv[1:]:
        with open(pathname, 'rb') as f:
            for line in f:
                timestamp = 0
                while line.startswith(b'#'):
                    match = pattern.match(line)
                    if match: timestamp, = map(int, match.groups())
                    line = next(f)
                out.write(time.strftime('%F %T ', time.localtime(timestamp)).encode('ascii'))
                out.write(line)
