Why don't you read what I write ?
Please click on the link (I mean "crontab.guru" webpage), which I sent you before !!! There it is explained in human language, when exactly the specified time-entry will be started, in the CRON configuration line . This website is designed for exactly this purpose, or primarily for this purpose:
yes I have already thanked @Tech for this...
Well... but I wrote it to you first... just that @Tech didn't notice it and that's why he wrote the same thing as me. I also gave you an explanation + links to the aforementioned crontabs.guru website. Then you wouldn't have to ask the same question every time :-) if you read what I explained to you. Besides everything, the mistake in my opinion is that you don't use the interpreter (/bin/bash </path/shell-script>) to run your shell script, but send the shell script directly to CRON.
I don't care. It's help for you. If you don't want help... OK...don't read it ;-). I take it then that you don't need to know :-). But without knowing how the CRON time data works, you will never do it well :-). For me personally, it was a waste of time trying to find out, and for you personally, it was just a burden on people who, instead of writing an "article" for you, could be doing something else.
