For regenerating test indices

mwscript-k8s --attach -- extensions/Translate/scripts/ttmserver-export.php --wiki testwiki --ttmserver eqiad-test

For regenerating the index for all wikis except where it is disabled:

SERVER=...
expanddblist translate | grep -v -e otrs_wikiwiki -e collabwiki -e officewiki -e ptwikisource > translate.list
cp translate.list translate.list-${SERVER}
mwscript-k8s --sal --comment "populating translation memory (ttmserver-export.php) on ${SERVER}" --local_dblist ./translate.list-${SERVER} --attach -- extensions/Translate/scripts/ttmserver-export.php --ttmserver ${SERVER}
