After having a conversation with Matthew off-list, it was decided that there is no mandated list of built-ins by POSIX. I was able to check the source for posh, and printf is not a built-in there. Therefore, to reliably use printf, we'd have to move the coreutils utility to /bin. So, I'm just going to commit the $ECHO stuff for now. We can always open up the printf conversation again. -- Dan -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
