I'm on Mac OS X 10.4.3 and using
Lftp | Version 3.1.0 | Copyright (c) 1996-2004 Alexander V. Lukyanov
and I enter
lftp
hit enter
and get the lftp prompt.. that's all. When I check my activity monitor lftp
is using an entire CPU (99%) and I have a 4-way! I assume it's just waiting
for command input so the question is.. is there a cheaper way to do so?
Here's the sample trace
from the Apple activity monitor
