You can use stat with a file glob:

$ stat -f "%m%t%N" /var/log/*.gz | sort -rn | head -1 | cut -f2-

The %m is the file time and the %N is the file name. That pattern is then used for a decorate-sort-undecorate to find the newest.

You can add sed to that to filter file names that have a regex pattern if desired.

You can use ls -ltr xyz*.gz and have the gz-file with the shortest modification time at the bottom of the listing
