Thank you for this. I've spent a few hours today searching and experimenting
to produce this code. I can almost understand the sed command. Everything
between the quotes is the action to be taken. The 's' is for substitution,
the / / is the whitespace to be replaced, the/@@/ is what the whitespace is
replaced with but I don't know what the @@ stands for, the g means it's
applied globally. I think what I just said is wrong because I have no clue
why the second and third substitution are there. And finally the output is
directed to $2. I'll have to wait until tomorrow evening to play with it. I
look forward to it.
thanks,
Jerome
