You might have more success in using awk in filter your control file.

Slight change in format of control file:

Code:
RHEL apple
    echo apple
RHEL bravo 
    ls -l bravo*
RHEL church 
    chmod church.txt

SUSE drive
    chown user1 drive.txt
SUSE eagle 
    echo "eagle flies"
SUSE feather
    ls -l feather*

HP-UX google
    sed 's/^Google.*$/&\
ACTION: go to www.google.com/' google.txt

HP-UX heartache
    ls -l heartache.txt* | awk '{ print $9 }'


I set the variable CGRP to be the 2nd param on your control lines. The awk output could be piped to a shell once your happy it's looking OK:

Code:
OPER_SYS="$1"
  
case $OPER_SYS in
    RHEL|SUSE|HP-UX)
    ;;
    *)  echo "Usage $0 [RHEL|SUSE|HP-UX]" >&2
        exit 2
    ;;
esac

awk -v SYS=$OPER_SYS '
  NF==2 && $1==SYS { exec = 1 ; print "CGRP="$2 ; next }
  NF==2 && $1 ~ "(RHEL|SUSE|HP-UX)" { exec = 0 }
  exec { print }' control


example:
Code:
$ ./do_control HPUX
Usage ./do_control [RHEL|SUSE|HP-UX]

$ ./do_control HP-UX
CGRP=google
    sed 's/^Google.*$/&\
ACTION: go to www.google.com/' google.txt

CGRP=heartache
    ls -l heartache.txt* | awk '{ print $9 }'

NAME

       subscription-manager-gui - Launches the UI client of the Subscription Manager.

SYNOPSIS

       subscription-manager-gui [--register]

DESCRIPTION

       subscription-manager-gui  opens	the  local client tool to manage subscriptions and installed products on Red Hat Enterprise Linux systems.
       The same tasks that can be performed by invoking subscription-manager can be performed in the GUI, including  registering  systems  with  a
       subscription management service, applying and removing subscriptions, and viewing the subscription status of installed products.

       The Subscription Manager UI can also be opened by selecting the Red Hat Subscription Manager item from the Applications > System Tools menu
       in RHEL 5.x or the System > Administration menu in RHEL 6.x.

OPTIONS

       --register
	      If a system has not yet been registered, then the GUI registration page can be opened immediately, as the Subscription  Manager  GUI
	      comes up. This is only relevant for unregistered systems; if this is used after a system is registered, the option is ignored.

REFERENCES

       For  procedures	and  tasks that can be performed in the Subscription Manager UI, check the Gnome help files (by pressing <F1>) or refer to
       the RHEL Subscription  Management  Guide  at  <https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Subscription_Management/1.0/html/Sub-
       scription_Management_Guide/index.html>.
