Rename part of the directory names?

The following command found the following directories.

$ find tmp/ -name "date=*" -type d
tmp/year=2022/month=05/date=27
tmp/year=2022/month=05/date=21
tmp/year=2022/month=05/date=29
tmp/year=2022/month=05/date=24
tmp/year=2022/month=05/date=31
tmp/year=2022/month=06/date=01
tmp/year=2022/month=06/date=02

I need to rename the directories by replacing date= to day=.

find tmp/ -name "date=*" -type d -exec rename s/date=/day=/g "{}" +;

However, the command doesn’t rename the directories?

I will need to implement it in Python.

>Solution :

If you want to do this from Python anyway, a subprocess is just unnecessary.

import os

for curdir, dirs, files in os.walk("/tmp"):
    for dirname in dirs:
        if dirname.startswith("date="):
            new = dirname.replace("date=", "day=")
            os.rename(os.path.join(curdir, dirname), os.path.join(curdir, new))
