compare two words, 1st word = file name appended with date and 2nd word = just date alone. compare should display the lines with different date [closed]

I am writing a script to compare the file name appended with date(YYY-MM-DD) with date of the file modified.

Example:

filename.2019-01-07.log   2019-01-09
filename.2019-01-07.log   2019-01-07
filename.2019-01-07.log   2019-01-07

Output:

filename.2019-01-07.log 2019-01-09

compare above two words with dates and display the file that has different dates.

please let me know the possible ways to perform this

Thanks

Delete every line that has a pattern repeated:

sed -r '/([-0-9]{10}).*1/d' input

or more accurate

sed -r '/([0-9]{4}-[0-9]{2}-[0-9]{2})[.]log.*1/d' input
