Re: Re: Removing files listed in another file

You cheat. The error message comes from the rm system command. :-)

Anyway, I believe the range operator is evaluated in scalar context since it returns a sequence number until the file is exhausted.

Context isn't determined by what the expression evaluates to. Context is determined by what is done to the value of an expression. The value of `..` is ignored, hence, `..` is in void context. Regardless whether it pushed a return value on the stack that got discarded anyway. -- Abigail	[reply] [d/l] [select]
