image-umount command help
More details and supported formats are supplied inside 'image-mount -h' script.
Usage
image-umount [--help|-h]
image-umount reset [path] (try)
image-umount image.ext [format] [mount-path] [--force-iso-stdmount]
--force-iso-stdmount -> force in iso mount 'mount -o loop' instead 'fuseiso'
Warning:
1) format must be explicily specified if file extension do not say itself the correct format.
2) Warning: all parameters are case sensitive.
Default parameters:
image-umount image.raw raw 0 \$HOME/mount/image
Minimal usage:
