Just create a wrapper for the awk script posted by Corona688...this way you can tweak the REJECT value based on a shell parameter.

bzgrep

BZGREP(1)						      General Commands Manual							 BZGREP(1)

NAME

       bzgrep, bzfgrep, bzegrep - search possibly bzip2 compressed files for a regular expression

SYNOPSIS

       bzgrep [ grep_options ] [ -e ] pattern filename...
       bzegrep [ egrep_options ] [ -e ] pattern filename...
       bzfgrep [ fgrep_options ] [ -e ] pattern filename...

DESCRIPTION

       Bzgrep  is  used to invoke the grep on bzip2-compressed files. All options specified are passed directly to grep.  If no file is specified,
       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  bzgrep  is  invoked as bzegrep or bzfgrep then egrep or fgrep is used instead of grep.  If the GREP environment variable is set, bzgrep
       uses it as the grep program to be invoked. For example:

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