check_distfiles

This script verifies checksums and sizes of all files in /usr/portage/distfiles directory according to portage manifests (/usr/portage/*/*/Manifest) and reports corrupt or excess (eclean-dist also deals with this kind) ones. Proposed usage: rm -i $(./check_distfiles).

Dependencies

• app-crypt/md5deep

Script assumes that DISTDIR and PORTDIR haven't been changed from default settings and that all overlays reside in /usr/local/portage or somewhere in /usr/portage/.
