This is to handle files with spaces in filenames (IFS= removes internal space field separator)
I dont know how to make this in one line (becouse of
besaname syntax, it cannot read filenames from stdin)
By the way, to compare files by content you can use
cmp command (but you need to compare each file with each).

GZDIFF(1) General Commands Manual GZDIFF(1)
NAME
gzcmp, gzdiff - compare compressed files
SYNOPSIS
gzcmp [ cmp_options ] file1 [ file2 ]
gzdiff [ diff_options ] file1 [ file2 ]
DESCRIPTION
gzcmp and gzdiff are used to invoke the cmp or the diff program on compressed files. All options specified are passed directly to cmp or
diff. If only 1 file is specified, then the files compared are file1 and an uncompressed file1.gz. If two files are specified, then they
are uncompressed if necessary and fed to cmp or diff. The exit status from cmp or diff is preserved.
SEE ALSO
cmp(1), diff(1), gzmore(1), gzgrep(1), gznew(1), gzforce(1), gzip(1), gzexe(1)
BUGS
Messages from the cmp or diff programs refer to temporary filenames instead of those specified.
