I'm still on rc6, so I guess I need to sync and emerge -uD world. However, it's probably in rc6 too, only I didn't notice it in the warning (<sheepish> as I don't read it as I know what the warning is about... only they added something! </sheepish>). Not here, forgetting the second > in >> wouldn't be destructive! I think this hint was featured in GWN a while back (yes, it was, comments are good things! =8^): -- snip -- # Based on a tips & tricks GWN feature. # Makes redirection to an existing file an error. # Use >> instead of > to append, or >| if overwriting is desired. set -o noclobber -- snip -- Put that in your .bashrc or whatever (my /etc/profile and .bashrc and all that are rather seriously customized, here, it's a file called in /etc/profile.d/, but my bashrcs and profiles source everything in /etc/profile.d/ so it's added to them). That way, using > to redirect to an existing file produces an error saying it already exists. The comment gives the solution, use >> to append, or use >| to force-overwrite the file. So... "echo whatever > /var/lib/portage/world" would NOT "be the end of my world" here! (double entendre/entente) -- Duncan - List replies preferred. No HTML msgs.
