in this case file needs to be scanned for each and every search pattern

---->
better way would be to accumalate search patterns together and use egrep in a single shot
Code:
>cat input.txt
DDD
CCC
EEE
AAA
BBB

Code:
>cat search_pattern.txt
var1=AAA
var2=BBB
var3=CCC

Code:
>cat try.ksh
# !/usr/bin/ksh

pattern=""
for val in `sed -e 's/.*=//' search_pattern.txt`
do
   pattern=$pattern$val"|"
done

egrep -e $pattern input.txt
exit 0

XcmsCCCOfColormap(3)						  XLIB FUNCTIONS					      XcmsCCCOfColormap(3)

NAME

       XcmsCCCOfColormap, XcmsSetCCCOfColormap - query and modify CCC of a colormap

SYNTAX

       XcmsCCC XcmsCCCOfColormap(Display *display, Colormap colormap);

       XcmsCCC XcmsSetCCCOfColormap(Display *display, Colormap colormap, XcmsCCC ccc);

ARGUMENTS

       display	 Specifies the connection to the X server.

       ccc	 Specifies the CCC.

       colormap  Specifies the colormap.

DESCRIPTION

       The XcmsCCCOfColormap function returns the CCC associated with the specified colormap.  Once obtained, the CCC attributes can be queried or
       modified.  Unless the CCC associated with the specified colormap is changed with XcmsSetCCCOfColormap, this CCC is used when the specified
       colormap is used as an argument to color functions.

       The XcmsSetCCCOfColormap function changes the CCC associated with the specified colormap.  It returns the CCC previously associated with
       the colormap.  If they are not used again in the application, CCCs should be freed by calling XcmsFreeCCC.  Several colormaps may share the
       same CCC without restriction; this includes the CCCs generated by Xlib with each colormap.  Xlib, however, creates a new CCC with each new
       colormap.
