Dump an image filesystem
dumpifs [-bmvxz] [-d dir] [-f file] [-u file] image [files]
QNX Neutrino, Linux, Microsoft Windows
The dumpifs utility dumps the contents of an image filesystem.
You can also use dumpifs with the -f or -x option to extract files from the image filesystem. The files are extracted into the current working directory, or into the directory you specify with the -d option. If you specify -b, the files are put directly into the directory; if you don't specify -b, the files are extracted to the pathname specified in the image.

This utility will not work on an image that has been built using a filter such as srec (for more information on image filters, see mkifs). If you wanted to run dumpifs on such an image, you would build the image omitting the filter stage in your mkifs buildfile (you would then need to run the filter by hand later in order to make a viable image for your target).
