Well, I will try your suggested answer in a while but have got a similar problem as well:

Code:
[root@SVHJ1315 SCRIPTING]# cat cmd
cat -n reduce_opt.sh "|" grep -iw
[root@SVHJ1315 SCRIPTING]# 
[root@SVHJ1315 SCRIPTING]# 
[root@SVHJ1315 SCRIPTING]# cat file
echo
[root@SVHJ1315 SCRIPTING]# 
[root@SVHJ1315 SCRIPTING]# cat command1 
#!/bin/sh

one=$(sed -n '1p' cmd)
two=$(sed -n '1p' file)
both=`echo $one $two`
echo `$both`
[root@SVHJ1315 SCRIPTING]# 
[root@SVHJ1315 SCRIPTING]# 
[root@SVHJ1315 SCRIPTING]# ls -lrt command1 
-rwxr-xr-x. 1 root root 94 Mar  2 20:58 command1
[root@SVHJ1315 SCRIPTING]# 
[root@SVHJ1315 SCRIPTING]# 
[root@SVHJ1315 SCRIPTING]# sh command1 
cat: invalid option -- 'i'
Try `cat --help' for more information.

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  invokes  grep  on  compressed  or  gzipped  files.   These  grep  options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other 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 the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
