Many Thanks Ravinder for the solution
And Thanks Rudic For the explanation.

Ravinder,
The single quote one worked.
Code:
/usr/bin/sed 's/'${a}'/'${b}'/g' /user/iomaint/tempo/gtm/sed/filetosedreplace

and the double quote one is not working as one can expect/ assume.

Thanks
Goutam

Hi RudiC,

I think I am not that good at explaining things/ issues.
Yes in command line , i was just using values in sed command and not using variables.

Will try to be more precise while narrating issues henceforth.
Anyways thanks again for the help. Happy that issue got resolved and most importantly i realized the fault.

pkgproto

pkgproto(1)							   User Commands						       pkgproto(1)

NAME

       pkgproto - generate prototype file entries for input to pkgmk command

SYNOPSIS

       pkgproto [-i] [-c class] [path1]

       pkgproto [-i] [-c class] [path1=path2...]

DESCRIPTION

       pkgproto scans the indicated paths and generates prototype(4) file entries that may be used as input to the pkgmk(1) command.

       If  no paths are specified on the command line, standard input is assumed to be a list of paths. If the pathname listed on the command line
       is a directory,	the contents of the directory is searched.  However, if input is read from stdin, a directory specified as a pathname will
       not be searched.

OPTIONS

       -i	       Ignores symbolic links and records the paths as ftype=f (a file) versus ftype=s (symbolic link).

       -c class        Maps the class of all paths to class.

OPERANDS

       path1	Pathname where objects are located.

       path2	Pathname which should be substituted on output for path1.

EXAMPLES

       Example 1: Examples of the use of pkgproto.1.

       The following two examples show uses of pkgproto and a partial listing of the output produced.

       Example 1:

       example% pkgproto /bin=bin /usr/bin=usrbin /etc=etc
       f none bin/sed=/bin/sed 0775 bin bin
       f none bin/sh=/bin/sh 0755 bin daemon
       f none bin/sort=/bin/sort 0755 bin bin
       f none usrbin/sdb=/usr/bin/sdb 0775 bin bin
       f none usrbin/shl=/usr/bin/shl 4755 bin bin
       d none etc/master.d 0755 root daemon
       f none etc/master.d/kernel=/etc/master.d/kernel 0644 root daemon
       f none etc/rc=/etc/rc 0744 root daemon

       Example 2:

       example% find / -type d -print | pkgproto
       d none / 755 root root
       d none /bin 755 bin bin
       d none /usr 755 root root
       d none /usr/bin 775 bin bin
       d none /etc 755 root root
       d none /tmp 777 root root

EXIT STATUS

       0	Successful completion.

       >0	An error occurred.

NOTES

       By  default,  pkgproto creates symbolic link entries for any symbolic link encountered (ftype=s). When you use the -i option, pkgproto cre-
       ates a file entry for symbolic links (ftype=f). The prototype(4) file would have to be edited to assign such file types as v (volatile),  e
       (editable), or x (exclusive directory). pkgproto detects linked files. If multiple files are linked together, the first path encountered is
       considered the source of the link.

       By default, pkgproto prints prototype entries on the standard output. However, the output should be saved in a  file  (named  Prototype	or
       prototype, for convenience) to be used as input to the pkgmk(1) command.
