What Others Think

(Assuming you have permissions to read memory, of course) dd is nice when you want to create a file of a particular size: dd if=/dev/zero of=myfile bs=1M count=1 if count is left off, myfile just keep growing until you interrupt dd with ^C. dd understands common suffixes such as M/MB/K/kB, see 'man dd' for more.
