Convert Bash history to Zsh history

bash-to-zsh-hist.py

#!/usr/bin/env python
# -*- coding: utf-8 -*-
# 
# This is how I used it:
# $ cat ~/.bash_history | python bash-to-zsh-hist.py >> ~/.zsh_history

import sys
import time


def main():
    timestamp = None
    for line in sys.stdin.readlines():
        line = line.rstrip('\n')
        if line.startswith('#') and timestamp is None:
            t = line[1:]
            if t.isdigit():
                timestamp = t
                continue
        else:
            sys.stdout.write(': %s:0;%s\n' % (timestamp or time.time(), line))
            timestamp = None


if __name__ == '__main__':
    main()

Worked like a charm !! Thank you 👍
Wondering why zsh framework doesn't have a feature to import the bash history as part of initial setup. 🤔

Thank you!!

Thanks!

Worked perfectly. Thanks

If you have UnicodeEncodeError:

    lines = []
    with open("/home/mmatrosov/.bash_history", "rb") as f:
        while bytes := f.readline():
            lines.append(bytes.decode("ascii", "backslashreplace"))
