Edit Question
Title
Body
Perl and PHP do this with backticks. For example, $output = `ls`; Returns a directory listing. A similar function, system("foo") , returns the operating system return code for the given command foo. I'm talking about a variant that returns whatever foo prints to stdout. How do other languages do this? Is there a canonical name for this function? (I'm going with "backtick"; though maybe I could coin "syslurp".)
