Let's break out the command and understand one by one highlighted in pale Yellow.

find . -type f

 # find . -type f -printf '%TY-%Tm-%Td\n' | sort | uniq -c

Find . -type f 

Find command will fetch only the files ( -type f ) within present directory ( . )

-printf '%TY-%Tm-%Td\n'

 # find . -type f -printf '%TY-%Tm-%Td\n' | sort | uniq -c

-printf '%TY-%Tm-%Td\n' will prints the modification time of files in e.g. 2020-04-26 format

sort | uniq -c

 # find . -type f -printf '%TY-%Tm-%Td\n' | sort | uniq -c

sort : It will sorts the output 

uniq -c : It will count the sorted output by date.

Feel free to use it,  thank me later ;)
