问题
I never use those .orig files, and I hate cleaning them up manually. Is there a way to configure hg revert to use the --no-backups option by default? I can't find it in the Mercurial manual
Using a shell alias is possible but isn't desirable.
回答1:
You can create an alias in your config file.
More details on the config file at http://www.selenic.com/mercurial/hgrc.5.html
Read the manual myself, and it looks like its changed somewhat since the last time I read it. I was going to suggest using defaults, but it appears that has been deprecated. The recommendation is to use aliases.
It appears an alias CAN override a built-in command, but obviously they don't recommend it.
So, you could do
[alias]
revert = revert --no-backup
but the recommendation would be to create a new command for yourself

Actually, the best way is to include the following two lines in your .hgrc file:
[defaults]
revert = --no-backup
