RE: [gentoo-user] In need of script/command that will parse out all the packages from "emerge -avu world"

[Daevid Vincent]

Thank you for the 'one liner'... I think it is exactly what I need. I'm
trying it out lately and let you know...

I did tweak it a smidge to be a little more flexible and robust:

locutus ~ # cat /usr/local/bin/emerge_select
#!/bin/sh

if test -z $1; then
  echo "required search argument is missing."
  echo "For example, use 'x11' for all the X11 ebuilds."
  exit
else
  emerge -va1 $(emerge -pvu world | \
     sed -n -r 's,^\[ebuild[^]]*\]\ ('$1'[^\ ]*).*$,\1,p' | \
     sed -r 's/-[^-]+(-r[0-9]+)*$//') \
  || until emerge --resume --skipfirst; do :; done
fi
