How can I check if two gzipped files are equal?
So, assuming that the file name is constant and the same command ( gzip “$name”) is used, one can check whether two files are different by using cmp and skipping the first bytes including the time: Note: the assumption that the same compression options is important, otherwise the command will always report the file as different.

How to get a Dataframe of all rows with a common user ID?

How to find common rows in two pandas?
This is essentially the algorithm you described as “clunky”, using idiomatic pandas methods. Note the duplicate row indices. Also, note that this won’t give you the expected output if df1 and df2 have no overlapping row indices, i.e., if In fact, it won’t give the expected output if their row indices are not equal.
