That is actually my problem. I need the variable to be valid in both places.
So is there a way to accomplish that (like in "while read -r line; do echo
${line}; done < somefile")?
(This is somewhat of a theoretical discussion, because I decided to do this
in perl anyway. - I seem to have a tendency to try to solve problems in an
inappropriate language, like OOP in c (you definitely learn how to cast
pointers that way ;) ). - But useful info for simple command line tasks
anyway.)
Bye,
Leonard.
