To do what he wants you have to know that ls -1U is the only way to get one output entry per readdir call. Reuben, you want to do it like this: ls -1U|head|xargs ls -l
Thanks for the hint about -1, but this doesn't seem to make any difference: I run "ls -1U|head" in a directory with lots of files (about 10,000) and it pauses for a minute or so before giving me my ten lines of output.
If I run the command again, then of course it runs almost instantly, so I'm not sure what use the loops are in the tests you give.
