Default value or argument

I used it for this function, which prints hashes:

function liner {



printf %${num_lines}s|tr " " "#"



Note the colon-dash, instead of the usual colon-equals.

Very similar but no use of `tr` for

function liner() {

local num_lines=${1:-42}

local line=$(printf %${num_lines}s)

echo ${line// /#}
