I don't know if this is the correct place to post but it looks right so.
I want to include something in my script that would use the user's input (a number) and based off of that number it would add X many of the user's specified chars.
So far I have

Code

clear
read -p "Amount? " A
read -p "Character? " C
A=${A//}
B=

I want B to be Char over and over A times.
Any ideas?
