Calculating the difference between dates

Hello!

i need to find files lower and bigger that one date i pass, i search in the man find, but i didn't find anything, the only that i find is the parameter -mtime, in this parameter i can pass a number of days, but i need to know the difference between dates, any built-in function for do this? or any parameter for pass to the find command?

Thanks!

hmm I am not shure if you could do that with some linux utility, maybe with scripting somehow, or ls -laR / and then use grep but this will have big overload

You can touch a temp file with the desired date, then use either
Code:
find path -newer tmp-file

or
Code:
find path ! -newer tmp-file

Note, with "! -newer", find will include files older OR EQUAL to the date.

I can't use this, because i need to pass a date, not a file.

It is worth using the search box at the head of the page for common questions like this. For example: -https://www.unix.com/shell-programming-scripting/24177-difference-between-two-dates.html

I found a lot of posts of this, but i don't believe that not exists a built-in function for do this, really I need to copy the function to my code? or what i didnt' understand?

Why not ?

Pass the date to the function, in that function create a temp file and touch with the passed date.

Then you can use the suggested find command for the mentioned purposes.
