Replace string of a file with a string of another file for matches using grep,sed,awk
I have a file comp.pkglist which mention package version and release . In 'version change' and 'release change' line there are two versions 'old' and 'new' Version Change: --> Release Change: -->

Code:
cat comp.pkglist 
Package list:  nss-util-devel-3.28.4-1.el6_9.x86_64 
Version Change: 3.28.4 --> 3.36.0 
Release Change: 1.el6_9 --> 1.el6 

Package list:   tzdata-2018e-3.el6.noarch 
Version Change: 2018e --> 2018g 
Release Change: 3.el6 --> 1.el6

for every package name I need to search in /tmp directory and replace it`s version from old version to new version and old release to new release:

Code:
grep -ri -n tzdata /tmp/. 
/tmp/core.pkglist:578:package tzdata                  2018e 3.el6    arch noarch  

sed -i '578s/2018e/2018g/' /tmp/core.pkglist // To replace '2018e by 2018g in 578th line.

How can I make it work for all packages in the comp.pkglist file to replace it`s old version to new version and old release to new release in any file under the directory /tmp.

The script should :
1) Run a loop with inputs as the name of the package in the comp.pkglist.
2) It should then grep for that package name in the /tmp directory to know which file contains the package.
Code:
grep -ri -n tzdata /tmp/. /tmp/core.pkglist:578:package tzdata                  2018e 3.el6    arch noarch

3) Then it should replace old version/old release of the same package with new version.
Code:
 sed -i '578s/2018e/2018g/' /tmp/core.pkglist

d-shlibmove

d-shlibmove(1)							  d-shlibs manual						    d-shlibmove(1)

NAME

       d-shlibmove - Move shared library files around in Debian package creation process

SYNOPSIS

       d-shlibmove [options] shared-library.so

DESCRIPTION

       Call this program in debian/rules as a replacement of dh_movefiles for shared library packages.

       It also checks debian/control for validity.

OPTIONS

       --movedev [filename] [relative dir-path]
	      Install  file  into  relative  directory path within the -dev package.  The dir will be created with install -d and the file will be
	      moved.

       --moveshl [filename] [relative dir-path]
	      Install file into relative directory path within the shared library runtime package.  The dir will be created with  install  -d  and
	      the file will be moved.

       --movedevdoc [filename]
	      Install file into the documentation directory of -dev package.  The dir will be created with install -d and the file will be moved.

	      Added in version 0.4

       --extralib [shared-library.so]
	      Install the shared library in the same package as the main shared library.

       --multiarch

	      By  default  d-shlibmove	installs  the  shared  library	and  any  extralibs  into  /usr/lib.   Add  this flag to install them into
	      /usr/lib/<architecture-tripplet> instead.

	      Added in version 0.48

       --commit

	      By default d-shlibmove runs in a dry-run mode. Add this flag to make the moving actually happen.

       --suffix [suffix to add to shared library package]

	      Add a suffix to shared library package.  This is a workaround when binary interface to package changed, and  some  fixup	to  Debian
	      packaging needs to be done.

	      Added in version 0.3

       --devsuffix [suffix to add to development package]

	      Add a suffix to development package.  For making incompatible development package.

       --shlibs-local [current-version]

	      Create  a  debian/shlibs.local  file  to	use,  and  specify  current-version  of  shared  library  package.   You  need	to  remove
	      debian/shlibs.local, because this only appends to, not overwrite.

	      Added in version 0.3

       --devunversioned

	      Install into unversioned development package.

	      Added in version 0.42

       --ignorelibdep

	      Suppress shlib dependency.  Useful when dynamically resolved e.g. using CDBS.

	      Added in version 0.42

       --c102

	      Add c102 suffix to package names, for C++ ABI transition.

	      Added in version 0.8

       --ldbl

	      Add dbl suffix to package names.

	      Added in version 0.35

       --include-a

	      Install the *.a files.  This is the default behavior.

	      Added in version 0.51

       --exclude-a

	      Avoid installing *.a files.

	      Added in version 0.51

       --include-la

	      Install the *.la files.  This is the default behavior.

	      Added in version 0.45

       --exclude-la

	      Avoid installing *.la files.

	      Added in version 0.45

       --override [override statement]
	      Add an overriding sed expression, which looks like --override s/libshared1-dev/libshared-dev/.  This expression  is  executed  after
	      the other rules.

	      Multiple --override can be specified.

	      Added in version 0.30

EXIT CODE

       Return 1 on error.

       Return 2 on dry-run.

       Return 0 on success.

EXAMPLES

       The following is a sample command-line of a hypothetical package installation.

       d-shlibmove    --commit	  --movedev    "debian/tmp/usr/include/*"    usr/include    --extralib	  debian/tmp/usr/lib/libhomeman-pthread.so
       debian/tmp/usr/lib/libhomeman.so
