Redhat has a shell-script called /usr/bin/zless:

#!/bin/sh
/bin/zcat "$@" | /usr/bin/less

(zcat is hard-linked to gzip and gunzip)

/usr/bin/zmore also exists and is the same but has a much more 
complicated shell script.

It sets some terminal options and stuff.

I attached some files there are a bunch more too.

These are the executables in redhats gzip package.

/bin/gunzip
/bin/gzip
/bin/zcat
/usr/bin/gunzip
/usr/bin/gzexe
/usr/bin/gzip
/usr/bin/zcmp
/usr/bin/zdiff
/usr/bin/zegrep
/usr/bin/zfgrep
/usr/bin/zforce
/usr/bin/zgrep
/usr/bin/zless
/usr/bin/zmore
/usr/bin/znew
