Hi.

Start by removing the spaces when assigning variables. The shell doesn't like it. Your expr commands, per se, are fine.

i.e.
Code:
rfiles = `expr $rfiles + 1`

Should be
Code:
rfiles=`expr $rfiles + 1`

If you said
Code:
X = 1

you've more chance of starting X-Windows than assinging 1 to variable X!

I would recommend not using expr, or backticks `

The shell has more elegant ways of doing this kind of thing without either.

i.e.
Code:
$ X=1
$ ((X = X + 1))
$ echo $X
2

Or
Code:
$ X=1
$ X=$((X + 1))
$ echo $X
2

It's also good practice to quote variables.

So:
Code:
if [ ! -d $file ]

Should be:
Code:
if [ ! -d "$file" ]

And it's generally not good to pass unknown-sized argument lists to commands in this way:
Code:
for filename in $file/*

Better is to write everything to a file, and then use a construct more like:
Code:
while read A B C etc; do
...
done < file

debconf-mergetemplate

DEBCONF-MERGETEMPLATE(1)					      Debconf						  DEBCONF-MERGETEMPLATE(1)

NAME

       debconf-mergetemplate - merge together multiple debconf template files

SYNOPSIS

	debconf-mergetemplate [options] [templates.ll ...] templates

DESCRIPTION

       Note: This utility is deprecated. You should switch to using po-debconf's po2debconf program.

       This program is useful if you have multiple debconf templates files which you want to merge together into one big file. All the specified
       files will be read in, merged, and output to standard output.

       This can be especially useful if you are dealing with translated template files. In this case, you might have your main template file, plus
       several other files provided by the translators. These files will have translated fields in them, and maybe the translators left in the
       english versions of the fields they translated, for their reference.

       So, you want to merge together all the translated templates files with your main templates file. Any fields that are unique to the
       translated files need to be added in to the correct templates, but any fields they have in common should be superseded by the fields in the
       main file (which might be more up-to-date).

       This program handles that case properly, just list each of the translated templates files, and then your main templates file last.

OPTIONS

       --outdated
	   Merge in even outdated translations. The default is to drop them with a warning message.

       --drop-old-templates
	   If a translation has an entire template that is not in the master file (and thus is probably an old template), drop that entire
	   template.
