Hi!
If I want to extract a character from a specific position of a string, I can use ${string:1:1} (if I want character at the position 1). How can I do the same thing, when the number of position is contained in the variable? ${string:$var:1}doesn't work, unfortunately.
Thanks in advance. (2 Replies)

Many thanks in advance. (12 Replies)
