Might help if you say what you are trying to achieve.

In particular, there are two lines like:

Code:

cat > $original_var

Perhaps what you actually want is

Code:

echo $original_var

(this shows the value of the variable: eg a filename?)
or perhaps

Code:

cat $original_var

(this shows the contents of a file if $original_var is a filename).

As evo2 said, it would help if we knew what was wrong. Provide useful details, like what the script is SUPPOSED to do, what it's ACTUALLY doing, etc.

Also, SPELL OUT YOUR WORDS, and write clearly.

You can mark the thread as "[SOLVED]" if it's solved.
