I'd say svn clone is the nearest equivalent as it does the initial fetch of data, no checkout is necessary after clone. it checks out master. Then you git-checkout to switch branch, which corresponds to svn switch. > svn commit:: > Pushes changes to the upstream respository from your working copy. > git commit -a:: > Saves changes to the working copy as a new revision in the local > repository. > > The need for "-a" (or not) because of git's staging area (the index) > here makes it more confusing than svn-commit for new users.

You'll need to push too in order to get a copy in a central repository. git-commit stays locally, and you need a place to push to. If your SVN repo isn't local this does not apply. git gives more freedom here. > svn copy:: > Duplicate something in working copy or repository, remembering history. > cp A B; git add B:: > Git doesn't have a direct equivalent of svn copy.

Git's ability to detect copies after-the-fact, mean that a > git-copy isn't necessary. svn copy is more like git checout -b, i.e. it's primary purpose is not to "copy" things, it is to create branches. You generally do not copy code (I hope). > svn move:: > Move and/or rename something in working copy or repository. > git-mv:: > Move or rename a file, directory or symlink. > > Git wins.

In svn this also renames a branch. > svn switch:: > Update the working copy to a different URL. > [no git equivalent]:: > git is distributed and can fetch from any number of remote repositories. > The URL can be typed on the command line of git-fetch, or can be given a > shortcut as a "remote".

Command is unnecessary. svn switch corresponds to git-checkout. I don't think you can change the URL unless the new URL actually points to the same repository. > Discussion > ---------- [...] > - svn revert: it's not easy to revert a single file in git; especially > once we bring the index into play.

Typically the user want to restore the index AND the working directory. Comparing typical workflows is more interesting than finding exact equivalents. -- robin - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
