Nick Craig-Wood	e055ed0489	rclone: change "ls" and add "lsl" and "md5sum" commands Changed "ls" command not to show modification time by default only size and path. That is because it is slow for nearly all the remotes as it requires extra metadata lookup. All remotes can look up files and sizes without extra operations. Added "lsl" which does what "ls" used to - namely show modification time, size and path. Added "md5sum" which produces the same output as the md5sum command - md5sums and paths that is.	2014-07-12 12:09:20 +01:00
