There is a huge difference between making a request more clear and removing the code about which you were asking questions. And, changing the requirements of your script after people have responded to your original question just confuses readers of your thread who are trying to help you and trying to make sense of the non-sensical responses to a post that no longer matches your original post.

If we go back to your original post (with CODE tags added, as captured in post #2 in this thread) and we assume that your file contains:

Code:

CMD_HG-120-V1
CMD_HG-120-V1-DEV-SUCCESS
CMD_HG-120-V2
CMD_HG-120-V2-DEV-SUCCESS
CMD_HG-120-V3

then what is assigned to the variable oldnum by the command:

Code:

oldnum=`cut -d '-' -f3 /tmp/file/new.txt

? Is that what you wanted?

What happens when you add 1 to a multi-line non-numeric string value using expr? Does it give you a number or does it print a diagnostic message instead?

If you're unwilling to answer these questions and the questions RudiC asked in post #2, this thread will be closed. We are here to help you learn how to fix your code to get the results you want. We are not here to act as your unpaid programming staff nor to try to guess at what you are trying to do.

DAPTUP(8)						      System Manager's Manual							 DAPTUP(8)

NAME

       daptup - wrapper script on 'apt-get update'

SYNOPSIS

       daptup [ --pre | --post | --last ] [ -h | --help ] [ --nocolor ]

OPTIONS

       --pre  Do only 'pre' stage: collect info that will be used as 'old'. Usually need to be specified only in apt hooks.

       --post If  appropriate option is enabled in config file, do only 'post' stage: collect 'new' info and output changes. Otherwise do nothing.
	      Usually need to be specified only in apt hooks.

       --last Output changes only. This option is supposed to be specified when you want to see changes made in the last update. Note that list of
	      outdated packages, if daptup is configured to output it, will be rebuilt.

       -h --help
	      prints the help

       --nocolor
	      Disables	color  output, useful for scripts or when output is not terminal. Now works only with --last option, however, you can dis-
	      able color globally in configuration file.

       daptup is a script that runs "apt-get update" inside and outputs list of packages recently entered to repo, list of packages which got  new
       updates, list of changes in 'watched' packages and, optionally, list of outdated packages.

       Starting with 0.8.0 version, daptup uses apt hooks and you don't need to explicitly call it if you use 'apt-get update'.

TROUBLESHOOTING

       If  daptup was interrupted while building the lists, the cached lists can stay in inconsistent state, which is inappropriate if you want to
       use --last option before the new update. There is nothing to do if interrupt was occured  at  the  moment  when	old  lists  were  building
       (besides  running  the  new  update). However, if interrupt was occured when the new lists were building, you can easily redo this stage by
       calling 'daptup --post'.

FILES

       /etc/daptup.conf
	      self-documented configuration file

       /var/spool/daptup/outdated
	      cached file with info about outdated packages
