Utility for accessing a disk or disk image formatted with BareMetal File System (BMFS).

GCC (C compiler) is required for building the BMFS disk utility.

In Ubuntu this can be completed with the following command:

sudo apt-get install gcc

Optionally, you can also install the Filesystem in Userspace (FUSE) headers.

sudo apt-get install libfuse-dev

make

You can copy the bmfs binary to a location in the system path for ease of use

bmfs --disk disk.image format 128M

You can also just use the default disk name, bmfs.img, and make the command simpler.

bmfs format 128M

In Linux/Unix/Mac OS X you can also format a physical drive by passing the correct path.

sudo bmfs /dev/sdc format

To list dist contents, use the ls command.

bmfs ls -l

Or specify a path.

bmfs ls /home -l

Sample output:

bmfs ls -l
       0 Mar 24 23:08:13 usr
       0 Mar 24 23:08:14 home
       0 Mar 24 23:08:16 lib
       0 Mar 24 23:08:24 boot

If the command is being run by a script, you can omit the color by using the --color option, like this:

bmfs ls --color never

Aliases for the ls command are dir and list.

To create a new file without any content on it, you can just use the touch command.

bmfs touch /etc/bashrc

You can also create a new file by copying one from the host file system.

bmfs cp ./some-script.sh /bin/some-script.sh

An alias for the cp command is copy.

To read a file from BMFS, you can use the cat command.

bmfs cat /home/john/.bashrc

Redirect the output to save it to a file.

bmfs cat /home/john/.bashrc >.bashrc

To delete a file, use the rm command.

bmfs rm /var/log/unused-file.txt

An alias for the rm command is delete.
