No output mean that there are no difference. Any differences would be displayed to the screen, or you could choose to direct them to a file as usual.
As for the return code, a zero value of $? indicates that there are differences and a value of one indicates that the files match.
I presume that these are quite large files if they take 3 minutes to work through. I know that there can be performance issues with grep and the -f flag with files over a certain size. is this time critical?
I hope that this helps,
Robin

curlopt_wildcardmatch
CURLOPT_WILDCARDMATCH(3) curl_easy_setopt options CURLOPT_WILDCARDMATCH(3)
NAME
CURLOPT_WILDCARDMATCH - enable directory wildcard transfers
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_WILDCARDMATCH, long onoff);
DESCRIPTION
Set onoff to 1 if you want to transfer multiple files according to a file name pattern. The pattern can be specified as part of the CUR-
LOPT_URL(3) option, using an fnmatch-like pattern (Shell Pattern Matching) in the last part of URL (file name).
By default, libcurl uses its internal wildcard matching implementation. You can provide your own matching function by the CUR-
LOPT_FNMATCH_FUNCTION(3) option.
A brief introduction of its syntax follows:
* - ASTERISK
ftp://example.com/some/path/*.txt (for all txt's from the root directory)
? - QUESTION MARK
Question mark matches any (exactly one) character.
ftp://example.com/some/path/photo?.jpeg
[ - BRACKET EXPRESSION
The left bracket opens a bracket expression. The question mark and asterisk have no special meaning in a bracket expression.
Each bracket expression ends by the right bracket and matches exactly one character. Some examples follow:
[a-zA-Z0-9] or [f-gF-G] - character interval
[abc] - character enumeration
[^abc] or [!abc] - negation
[[:name:]] class expression. Supported classes are alnum,lower, space, alpha, digit, print, upper, blank, graph, xdigit.
[][-!^] - special case - matches only '-', ']', '[', '!' or '^'. These characters have no special purpose.
[[]\] - escape syntax. Matches '[', ']' or ''.
Using the rules above, a file name pattern can be constructed:
ftp://example.com/some/path/[a-z[:upper:]\].jpeg
PROTOCOLS
This feature is only supported for FTP download.
EXAMPLE
See https://curl.haxx.se/libcurl/c/ftp-wildcard.html
AVAILABILITY
Added in 7.21.0
RETURN VALUE
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
