> Can't you already do this with awk? This is not a very useful comment. Everything that coreutils do can be done with some other software. Since 'join' can do 1 field join, it is natural to ask for multiple field join. After all, people use coreutils for its convenience in certain aspects. Why not make it more convenient?
The current working flow in coreutils is like from the stone age, while many other open source projects use more advanced dvcs like github or bitbucket. I had tried to send some patch before. Besides the above mentioned inconvenience, I have to get my signature from GNU office, which they never reply my email. If coreutils wants me people to contribute, the patching/submission processes must be improved. The current process is way inconvenience for new contributors. -- Regards, Peng
