Repeats a character how many times you want.

repeat.sh

# 
#	Repeats a character how many times you want.
#
#	$1 The character you want.
#	$2 How many times you want.
# 
repeat() {
	character=$1
	times=$2
	string=$(printf "%""$times""s")
	
	echo "${string// /$character}"
}

in ruby

repeat() {
ruby -e "puts "$1" * $2"
}

Ruby is awesome. I always postpone to do something with it...
I hope I can find time to learn more "after the rain".

a ruby script:

#!/bin/env ruby

puts ARGV[0] * ARGV[1]

ActionScript:

function repeat( p_string : String, p_times : Number ) : String {
return Array([].length = p_times).join(p_string);
}
