But, since this is in this GUI interface, you can clearly see which are which and select only the files you want to affect. If you have so many files that you have to select indiscriminately, then the command-line is probably a better choice anyway. In any case, my proposed change prompts for each part of the change, so you _can_ just select everything, press ^J, and then say "Yes" to only one of the prompts. > > As a side note, `git clean untracked-file` won't do anything with a > > default configuration, you have to explicitly `-f` it.

You are entirely correct, this was just a massive brain fart. Every time I wrote `git revert` in my head I was actually thinking of exactly what Git Gui does, reverting working copy changes by checking out the file. I should have written "reverting using `git checkout`". My apologies! In my defence, I have over the past few days found myself digging into code hosted in SVN repositories, and `svn revert` does exactly what `git checkout` does to an unstaged modified file. :-) Jonathan Gilbert On Sat, Nov 2, 2019 at 8:12 PM Pratyush Yadav <me@xxxxxxxxxxxxxxxxx> wrote: > > On 30/10/19 12:16PM, Jonathan Gilbert wrote: > > On Wed, Oct 30, 2019 at 4:09 AM Bert Wesarg > > bert.wesarg-at-googlemail.com |GitHub Public/Example Allow| > > <xlwsizdz58ciy7t@xxxxxxxxxxxxxx> wrote: > > > in Git speak, that operation is called 'clean' (see 'git clean') why > > > should we overload the 'revert' operation here? > > > > It's less about overloading the 'revert' operation as overloading the > > UI action which is currently called "Revert".
