Works for me. Outer loop reads a line from file1 then reads a line from file2 and so on:

Code:
while read file1;do echo $file1;while read file2;do echo $file2;done < file2;done < file1
This is file #1.
This is file #2.
This is file #1.
This is file #2.
This is file #1.
This is file #2.

NAME
xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files SYNOPSIS
xzcmp [cmp_options] file1 [file2] xzdiff [diff_options] file1 [file2] lzcmp [cmp_options] file1 [file2] lzdiff [diff_options] file1 [file2] DESCRIPTION
xzcmp and xdiff invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), or bzip2(1). All options specified are passed directly to cmp or diff. If only one file is specified, then the files compared are file1 (which must have a suffix of a supported com- pression format) and file1 from which the compression format suffix has been stripped. If two files are specified, then they are uncom- pressed if necessary and fed to cmp(1) or diff(1). The exit status from cmp or diff is preserved. The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils. SEE ALSO
cmp(1), diff(1), xz(1), gzip(1), bzip2(1), zdiff(1) BUGS
Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified. Tukaani 2009-07-05 XZDIFF(1)
