Content-type: text/plain; charset=utf-8; format=flowed Content-transfer-encoding: 7bit ${var// /} When doing that sort of substitution, is is possible to test for newlines? I'm playing with a function that grabs history and I'm trying to strip off the leading numbers. At one point I have the output captured in a variable and various forms of substitution come close, but the substitution treats the entire variable as one entity whereas I want the substitution to be performed fresh on each new line of output. I can't find any specific newline character. OTOH if the variable was an array there'd probably be some way of processing each line as a separate entity, which would serve fine. I know I'm close, but I can't quite bag it.
