Listmates,

I don't know if this can be done, but I was trying to get a c style for loop to dereference the counter i to the equivalent command line parameter $1, $2, etc.. Like:

for ((i=1;i<=$#;i++)); do echo "\$$i = ${$i} done

Look into the "let" and "eval" built-ins (in the BASH manual page). Understanding BASH array variables may also help.
