The question was... "So, what's with the hyphen after = ?? " in relationship to files in /usr/lib/systemd/system/irda.service containing EnvironmentFile= and 2 examples were given. In order to answer the question I would not have used grep since there is no need to do that as the question was well worded and succinct. If the answer given in the man page isn't sufficient for *your* needs then you need to ask another question. And, FWIW, .... grep "=-" /usr/lib/systemd/system/* | grep EnvironmentFile produces many entries such as... /usr/lib/systemd/system/ypbind.service:EnvironmentFile=-/etc/sysconfig/network /usr/lib/systemd/system/ypbind.service:EnvironmentFile=-/etc/sysconfig/ypbind On my system....so I'm not sure why you don't see that. -- If I wanted a blog or social media I'd go elsewhere -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
