At a first step,to determine the reason,can you show us the output of
a problematic file,plus a working file with:
cat -A file |tail -n 2

cat is able to display these kind of symbols,included the end of
line character as ($) with the -E switch and the tab character as (^I) with the
Then it's a matter of cat'ing the file and feed it to sed.
cat -E $filename| sed '$!d;/$/!d'
What I want to see from Warren and in a way that also would be beneficial for
the list,is to translate the human logic to actions and code.
Here is what I am thinking.
find the files in this directory with suffix let's say *.sql and do for them:
if one of these has:
first (a) condition and maybe a second condition (b) etc ...
then do: the (A) *action* and possible a (B) action ect ...
otherwise (else) do: (C) action,or continue, or exit
Then we can translate the above paragraph to a snippet of code and do the job.
That way,I believe Warren himself can find the solution not only for
this problem but for the others will come.
