It looks like some eclasses just resort to sed for that: ohnobinki@ohnopublishing ~/portage $ grep -Re 'MAKEOPTS.*-j' /usr/portage/eclass /usr/portage/eclass/toolchain.eclass: export MAKEOPTS="${MAKEOPTS} -j1" /usr/portage/eclass/waf-utils.eclass: local jobs=$(echo -j1 ${MAKEOPTS} | sed -r "s/.*(-j\s*|--jobs=)([0-9]+).*/--jobs=\2/" ) /usr/portage/eclass/perl-module.eclass: export HARNESS_OPTIONS=j$(echo -j1 ${MAKEOPTS} | sed -r "s/.*(-j\s*|--jobs=)([0-9]+).*/\2/" ) So if you did something dirty like that, it would be enough to make people happy ;-). -- binki Look out for missing or extraneous apostrophes!
