Hi I m creating a file which will serve as a virtual harddisk .
I m using following command to create a file.
I have following doubts regarding the operation.
1) In above example i m creating a file with byte size of 1M .However in windows O/S (Not sure about linux here) whenever a new partition is formatted the default size will be 4096 bytes.
2) According to my assumption it doesn't make any difference as OS is anyway going to format it using mkfs.(whatever filesystem we specify).
Correct me if i m wrong.

mkfs.bfs
MKFS.BFS(8) System Administration MKFS.BFS(8)NAME
mkfs.bfs - make an SCO bfs filesystem
SYNOPSIS
mkfs.bfs [options] device [block-count]
DESCRIPTION
mkfs.bfs creates an SCO bfs filesystem on a block device (usually a disk partition or a file accessed via the loop device).
The block-count parameter is the desired size of the filesystem, in blocks. If nothing is specified, the entire partition will be used.
OPTIONS -N, --inodes number
Specify the desired number of inodes (at most 512). If nothing is specified, some default number in the range 48-512 is picked
depending on the size of the partition.
-V, --vname label
Specify the volume label. I have no idea if/where this is used.
-F, --fname name
Specify the filesystem name. I have no idea if/where this is used.
-v, --verbose
Explain what is being done.
-c This option is silently ignored.
-l This option is silently ignored.
-h, --help
Display help text and exit.
-V, --version
Display version information and exit. Option -V only works as --version when it is the only option.
EXIT CODES
The exit code returned by mkfs.bfs is 0 when all went well, and 1 when something went wrong.
SEE ALSO mkfs(8)AVAILABILITY
The mkfs.bfs command is part of the util-linux package and is available from https://www.kernel.org/pub/linux/utils/util-linux/.
