  • Revised approach to and3k's version, using pipes and read rather than command substitution. This does not require fiddling with IFS when paths have whitespace, and does not risk hitting command-line size limits. It's less verbose on the missing files, but it stops iterating at the first file that's missing, so it should be definitely faster. I expanded all the qlist options to be more self-describing.

    emerge -av1 `qlist --installed --nocolor | uniq | while read cp; do qlist --exact $cp | while read file; do test -e $file || { echo $cp; echo "$cp: missing $file (and maybe more)" 1>&2; break; }; done; done`

  • This loops through all installed ebuilds and checks if every file that should be installed is still there and if not adds it to emerge. It includes a verbose output to stderr too. If you have packages installed that have whitespace in their filenames you have to change the IFS to "newline".

    emerge -av1 $(for e in `qlist -I --nocolor | uniq`; do for f in `qlist -e $e`; do if test ! -e $f; then echo $e; echo $e: missing $f 1>&2; fi; done; done)

  • Problem arises when ebuild gets removed from portage and you end up with old and unmaintained package that you cannot find standard way. This oneliner will give you list of those packages. Show Sample Output
