An easy one for most of you,
given a piece of code like this:
var_1="first var"
var_2="second var"
var_3="third var"
read user_input
# user enters "2"
echo "User selected the ????iation"
# expected result is: "User selected the second variation"
Is there some kind of recursive variable resolution, ie. like
$var_$user_input, that would resolve into the expected result and if yes,
how would I have to code this?
What book would you recommend for a beginner who wants to write some "more
than trivial" shell scripts? (Or should I leave it at that and learn Pearl
instead?)
TIA
Robert
