flymolo has asked for the wisdom of the Perl Monks concerning the following question: (programs and processes)

`some command` will give me the text of the executed program. system("command") will return the return value, but running the program twice might change text and/or return values. Is there any easy way to do this? Right now I'm thinking system("command >file") but then I'd have a file I don't need.
