Shell Programming and Scripting

for i in {1..100};do printf "%s" "#";done;printf "\n"

That doesn't work in the ksh93 I have.

The function the OP referred to (from my book) concatenates 3 instances on each iteration.

Quote:

bash3

Code:

printf -vch  "%100s" ""
printf "%s\n" "${ch// /#}"

That's a nice idea.

I used it (somewhat modified) in a couple of functions so that the character and number of repetitions can be easily specified:

The first function stores the result in a variable, by default $_REPEAT.

The second prints the result.

Code:

_repeat() ## USAGE: _repeat STRING NUM [VAR]
{
 eval "printf -v ${3:-_REPEAT} '$1%.0s' {1..$2}"
}

repeat() ## USAGE: repeat STRING NUM
{
 eval "printf '$1%.0s' {1..$2} "
 echo
}
