create_ln.py同步nginx中两个文件夹的内容

在nginx的sites-avaliable中，增加新文件之后，需要创建软连接到sites-enable里，reload才会生效，所以写了如下脚本：

• create_ln.py

#!/usr/bin/env python3
import os
from pathlib import Path


def run_and_echo(cmd: str) -> int:
    print('-->', cmd)
    return os.system(cmd)


def main():
    pwd = Path(__file__).resolve().parent
    ps = pwd.glob('*.*')
    target = pwd.parent / 'sites-enabled'
    count = 0
    for i in ps:
        name = i.name
        p = target.joinpath(name)
        if name.endswith('.bak') or name.endswith('.py') or p.exists():
            continue
        print(f'creating ln of {name} ...')
        run_and_echo(f'sudo ln -s {i} {p}')
        count += 1
    if not count:
        print('No need to create soft link.')


if __name__ == '__main__':
    main()

Usage::

chmod +x create_ln.py
sudo mv create_ln.py /etc/nginx/sites-available/
cd /etc/nginx/sites-available/
./create_ln.py
sudo nginx -t
