Fed up of Mac os "sed"

I've wanted to set up that symlink for a while (it's annoying to always be modifying scripts to use gsed instead of sed) but I was worried some OSX system script somewhere would fail because it expected some OSX-sed-specific behaviour.

Have you noticed any of those types of problems since setting this up?

No, not yet.

But the issue I found is that you can't share script with mac community, but you can with the linux community. It's more a feature than a bug in my opinion!
