I just stumbled upon an interesting case:
$ find po -name ro.po -exec msgfmt --statistics {} \;
66 translated messages.
705 translated messages, 14 fuzzy translations.
52 translated messages.
485 translated messages.
527 translated messages, 22 fuzzy translations, 1 untranslated message.
but
$ find po -name ro.po -exec msgfmt --statistics {} +
po/sublevel3/ro.po:21: duplicate message definition...
po/sublevel4/ro.po:19: ...this is the location of the first definition
msgfmt: found 1 fatal error
In this particular case it is actually necessary to issue a separate
'msgfmt' command for each .po file, while in most other cases the '{} +'
form is better (and shorter to write ;).
Kind reegards,
Andrei
