Hi.
I'm trying to copy multiple folders from the remote machine to the local machine. I wrote a batch file to run an ftp window.
The problem I am having is that the only command to copy files is mget *, and this copies only files, not folders.
For example, ftp ts555

mkfs.btrfs
MKFS.BTRFS(8) System Manager's Manual MKFS.BTRFS(8)NAME
mkfs.btrfs - create an btrfs filesystem
SYNOPSIS
mkfs.btrfs [ -A alloc-start ] [ -b byte-count ] [ -d data-profile ] [ -l leafsize ] [ -L label ] [ -m metadata profile ] [ -n nodesize
] [ -s sectorsize ] [ -h ] [ -V ] device [ device ... ]
DESCRIPTION
mkfs.btrfs is used to create an btrfs filesystem (usually in a disk partition, or an array of disk partitions). device is the special file
corresponding to the device (e.g /dev/sdXX ). If multiple devices are specified, btrfs is created spanning across the specified
devices.
OPTIONS -A, --alloc-start offset
Specify the offset from the start of the device to start the btrfs filesystem. The default value is zero, or the start of the
device.
-b, --byte-count size
Specify the size of the resultant filesystem. If this option is not used, mkfs.btrfs uses all the available storage for the filesys-
tem.
-d, --data type
Specify how the data must be spanned across the devices specified. Valid values are raid0, raid1, raid10 or single.
-l, --leafsize size
Specify the leaf size, the least data item in which btrfs stores data. The default value is the page size.
-L, --label name
Specify a label for the filesystem.
-m, --metadata profile
Specify how metadata must be spanned across the devices specified. Valid values are raid0, raid1, raid10 or single.
-n, --nodesize size
Specify the nodesize. By default the value is set to the pagesize.
-s, --sectorsize size
Specify the sectorsize, the minimum block allocation.
-V, --version
Print the mkfs.btrfs version and exit.
AVAILABILITY
mkfs.btrfs is part of btrfs-progs. Btrfs is currently under heavy development, and not suitable for any uses other than benchmarking and
review. Please refer to the btrfs wiki http://btrfs.wiki.kernel.org for further details.
