Whenever you replace something in a text file you either have to memory map the whole in C, make changes, then close the file. Or. Loop through the original file processing line by line and write the new file. In Linux
Code:
sed -i

will do this - update in place. (It does the loop behind closed curtains). Other UNIXES, no.

We need:
Your shell and your unix OS to go further.

And it would be nice to know why loops are out of the question. Sounds misguided to me.

Excel::Template::Container::Loop(3pm)			User Contributed Perl Documentation		     Excel::Template::Container::Loop(3pm)

NAME
Excel::Template::Container::Loop - Excel::Template::Container::Loop PURPOSE
To provide looping NODE NAME
LOOP INHERITANCE
Excel::Template::Container ATTRIBUTES
o NAME This is the name of the loop. It's used to identify within the parameter set what variables to expose to the children nodes each iteration. CHILDREN
None EFFECTS
None DEPENDENCIES
None USAGE
<loop name="LOOPY"> ... Children here ... </loop> In the above example, the children nodes would have access to the LOOPY array of hashes as parameters. Each iteration through the array would expose a different hash of parameters to the children. These loops work just like HTML::Template's loops. (I promise I'll give more info here!) There is one difference - I prefer using Perl-like scoping, so accessing of variables outside the LOOP scope from within is perfectly acceptable. You can also hide outside variables with inner values, if you desire, just like Perl. AUTHOR
