vidma - Virtual Disks Manipulator
vidma INPUT_FILE NEW_SIZE_IN_MB [OUTPUT_FILE]
vidma is a utility for manipulating virtual disk images. It can show basic information about the image or resize it. Resizing is done by in-place modification of a file holding the image or by creating modified copy of such file.
If you provide only INPUT_FILE argument, then
vidma checks whether this
file is a virtual disk image, i.e. has one of supported FORMATS, and shows
information about it.
Giving additionally NEW_SIZE_IN_MB value, which should be a positive integer,
vidma to perform a resize operation on the INPUT_FILE. Unless
you provide OUTPUT_FILE, resizing will be performed in-place.
NEW_SIZE_IN_MB is the new desired size of virtual disk, using megabyte
(1048576 bytes) as a unit.
By specifying OUTPUT_FILE you prevent
vidma from modifying INPUT_FILE.
OUTPUT_FILE becomes then an appropriately modified copy of INPUT_FILE.
With no arguments,
vidma displays its version and usage information.
vidma command expects INPUT_FILE to be valid virtual disk image in one
of currently supported formats:
There is no free space checking before resizing and there is no error handling. This means you won't notice a failure if it will happen. Obviously this has to be fixed in future versions.
To reduce possible damages of in-place operation ALWAYS BACKUP YOUR IMAGE or do not use in-place operations at all by providing OUTPUT_FILE every time.
