Mention that a target path argument is mandatory unless
the -l option is supplied. Also mention about the existence
of the -l option, which was previously not announced.
$ btrfs restore -v /dev/sdb3
usage: btrfs restore [options] <device>
Try to restore files from a damaged filesystem (unmounted)
-s get snapshots
-v verbose
-i ignore errors
-o overwrite
-t tree location
-f <offset> filesystem location
-u <block> super mirror
-d find dir
$ echo $?
129
After specifying a target path, the command works as expected:
$ btrfs restore -v /dev/sdb3 files2/
Restoring files2/file1
Done searching
$ echo $?
0
V2: Updated command synopsis by suggestion of Anand Jain.
