rdebsums - a recursive debsums
rdebsums --help | [ debsum options ] [ --others ] package
rdebsums runs debsums(1) over a given package and all its dependencies. It can be used to make sure a problem with a package is not due to file corruption.
All but the last element of the command-line and options understood by rdebsums are sent to debsums(1).
Check the package aptitude and all its dependencies:
The same while being significantly less verbose
rdebsums -s aptitude
rdebsums is quite slow - essentially due to dpkg-query not being extremely fast.
Currently, rdebsums will be confused by virtual packages.
--others is actually nearly useless, as you often end up checking nearly all packages. You'll most probably win time by running debsums without arguments.
