Hi, Cool tool. Just looking at the help output on the console I found a small typo.
Kind regards, Andreas Philipp diff --git a/btrfs.c b/btrfs.c index cc55599..f3e5d8d 100644 --- a/btrfs.c +++ b/btrfs.c @@ -633,7 +633,7 @@ static struct Command commands[] = { "Add a device to a filesystem" }, { -1, "rm-dev", "-R", "<dev> [<dev>..] <path>\n" - "Remove a device to a filesystem" + "Remove a device from a filesystem" }, /* coming soon { 2, "label", "-m", "<label> <path>\n" On 17.02.2010 21:02, Goffredo Baroncelli wrote: > Hi all, > > enclosed in the next two emails you can find two patches which introduce a > new > program called "btrfs".
