Linux目录权限读写但不删除(Linux directory permissions read write but not delete)

是否可以设置目录权限,以便一个组能够读取和写入文件和子目录但不删除任何内容?


Is it possible to setup directory permissions such that a group is able to read and write files and subdirectories but not delete anything?

这感觉有点哈克....我不以此为荣。 但它使你的数据集工作。

df['cummulative_value'] = (df.groupby(df['Date'].dt.strftime('%Y%m'))['cummulative_value']
                            .transform(lambda x: np.where(x.ge(-71).cumprod()
                            .shift(1).fillna(1),x,1000)))

输出:

        Date  cummulative_value
0 2017-01-08                 -3
1 2017-01-09                 -6
2 2017-01-10                -72
3 2017-01-11               1000
4 2017-01-26               1000
5 2017-02-07                 -5
6 2017-02-14                 -6
7 2017-02-21                 -6

This feels a bit hacky.... I am not proud of it. But it make work for your dataset.

df['cummulative_value'] = (df.groupby(df['Date'].dt.strftime('%Y%m'))['cummulative_value']
                            .transform(lambda x: np.where(x.ge(-71).cumprod()
                            .shift(1).fillna(1),x,1000)))

Output:

        Date  cummulative_value
0 2017-01-08                 -3
1 2017-01-09                 -6
2 2017-01-10                -72
3 2017-01-11               1000
4 2017-01-26               1000
5 2017-02-07                 -5
6 2017-02-14                 -6
7 2017-02-21                 -6
