Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

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 $(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)

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".
