[ILUG] Bourne[-again] shell

[Peter Flynn]

How's your shell? I have a script with variables

SURNAME1=foo
SURNAME2=bar
etc
SURNAME9=blort

and I want to reference these in a loop. My bash is rusty,
to say the least, and I don't do Perl.

while [ something]; do

COUNTER=(some function which increments the counter)

do something with ${SURNAME$COUNTER}
                  ^^^^^^^^^^^^^^^^^^ This is causing an error

done


The error says "bad substitution" but I can't see why. Or is
there something non-obvious needs to be done to the $COUNTER
to force it to evaluate and catenate with the string SURNAME?
