Well, considering that pd-ksh will fail in the same manner that bash does, I'm not sure that this is any great loss. But just use
#! /usr/bin/ksh
on Linux to invoke pd-ksh. I believe that the real ksh is available for Linux, but I don't know how you get it. You need to stop doing
some-command | read this that
to get your script to work with bash or pd-ksh. If you can't think of anything else,
some-command > tempfile
read this that < tempfile
rm tempfile
should do it.

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  is used to invoke the grep on compress'ed or gzip'ed files. All options specified are passed directly to grep.  If no file is speci-
       fied, then the standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed	if  necessary  and
       fed to grep.

       If  zgrep  is invoked as zegrep or zfgrep then egrep or fgrep is used instead of grep.  If the GREP environment variable is set, zgrep uses
       it as the grep program to be invoked. For example:

	   for sh:  GREP=fgrep	zgrep string files
	   for csh: (setenv GREP fgrep; zgrep string files)
