So let me ask this, "Do you like to have gls, guniq in your /opt/local/bin? Is there any case that removing "g" prefix causes any problems? I think they are by default off because you expect ls from BSD and not from GNU on Mac OS X by default. It might break other shell scripts.
I doubt it. I think almost all scripts starts with "#!/bin/bla" or "#!/usr/bin/bla" so installing GNUs in /opt/local/bin will not break anything, if you don't run a script like "sh somescript.sh" or "awk -f somescript.awk"
Imagine a bash script using ls, but it is expecting BSD ls, not GNU ls. It may fail because the options of these programs are different (except the POSIX subset of arguments).
That makes sense, but in that case, shell scripter should specify exact bin path like LS=/bin/ls # BSD ls $LS -bsdoption something" instead. And you can easily force scripts to which ls to use like below. $ PATH=/usr/bin:/bin:/usr/sbin:/sbin somescript.sh In default case (g prefix), there's no easy way to fix this other than renaming bins in script or re-installing coreutils with "with_default_names" just as you suggested me.
