You need to define clearly the aims, then break them down into smaller tasks. Try to draw the process or write it out. Keep clear that the three basic logical flow types are:-
  • Sequence
  • Branch
  • Loop
The sequence can be any number of statements (including the other two) and calls to commands etc.


Is there a reason your peers are 'not recommending' tar? Do they not trust it, or is it that they just haven't suggested it.

It is nice that your script uses functions (Local2Remote etc.) but as they are called just once, it seems a little odd. Perhaps it makes the main part of the scripts easier to read, but I also worry that you are trying to call zip within sftp and I'm not sure it will work.

I would suggest that your two test at the beginning of the main part are the wrong way round. You should test for the lock-file first, then the configuration file.

I'm not too sure on why you exec < ${FILE_CONFIG} in your code the read in in your loop. Could you just simply . ${FILE_CONFIG} which will execute the file in the current shell, i.e. any variables or functions set are then available to the script that called it.

Your loop with a break and the eval statements are a little perplexing too.

Can you explain what your input file FILE_CONFIG will contain and the eventual process you want to achieve? There may be a simpler way to get there.


There is definitely some good stuff in the script though, so don't lose confidence. I'm just trying to understand the overall objective and trying to get the best outcome for you in a way that you can maintain.

dh_installdebconf

DH_INSTALLDEBCONF(1)                                                 Debhelper                                                DH_INSTALLDEBCONF(1)

NAME

       dh_installdebconf - install files used by debconf in package build directories

SYNOPSIS

       dh_installdebconf [debhelperoptions] [-n] [--params]

DESCRIPTION

       dh_installdebconf is a debhelper program that is responsible for installing files used by debconf into package build directories.

       It also automatically generates the postrm commands needed to interface with debconf. The commands are added to the maintainer scripts by
       dh_installdeb. See dh_installdeb(1) for an explanation of how that works.

       Note that if you use debconf, your package probably needs to depend on it (it will be added to ${misc:Depends} by this program).

       Note that for your config script to be called by dpkg, your postinst needs to source debconf's confmodule. dh_installdebconf does not
       install this statement into the postinst automatically as it is too hard to do it right.

FILES

       debian/package.config
           This is the debconf config script, and is installed into the DEBIAN directory in the package build directory.

           Inside the script, the token #DEBHELPER# is replaced with shell script snippets generated by other debhelper commands.

       debian/package.templates
           This is the debconf templates file, and is installed into the DEBIAN directory in the package build directory.

       debian/po/
           If this directory is present, this program will automatically use po2debconf(1) to generate merged templates files that include the
           translations from there.

           For this to work, your package should build-depend on po-debconf.

OPTIONS

       -n, --no-scripts
           Do not modify postrm script.

       -- params
           Pass the params to po2debconf.

SEE ALSO

       debhelper(7)

       This program is a part of debhelper.
