Dump an image filesystem
dumpifs [-f file] [-m] [-vxb -u file] image [files]
QNX Neutrino, Linux, Microsoft Windows
- -b
- When using the -x option, extract to
the basenames of the files.
- -f file
- Extract named file.
- -m
- Display MD5 Checksum.
- -u file
- If the image is compressed, put an uncompressed copy in file.
- -v
- Verbose operation. Specify more than one v to
display more information.
- -x
- Extract the files specified after the image.
If you also specify -b, the files are put into the current
directory; if you don't specify -b, the files are extracted to
the pathname specified in the image.
The dumpifs utility dumps the contents of an image filesystem.
It can also be used to extract files from the image filesystem.

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
build file (you would then need to run the filter by hand later in
order to make a viable image for your target).
