E.g. echo modified >> a.txt git add a.txt git checkout -- a.txt (1) git checkout HEAD -- a.txt (2) (1) This will do nothing to your file 'a.txt' in your workdir because the index and the workdir are identical (2) This will reset your file to the state before you run that bogus echo modified >> a.txt comand Greetings, Peter ``` ## Aaron Gray, 2009-05-31 16:50 Subject: Re: Resetting working files Message-ID: <9719867c0905310950x153db8efw179a8a10ac3f4640@mail.gmail.com> URL: https://gitlist.dev/e/9719867c0905310950x153db8efw179a8a10ac3f4640%40mail.gmail.com In-Reply-To: <20090531163225.GE3674@debian.b2j> ``` 2009/5/31 bill lam > > On Sun, 31 May 2009, Peter Baumann wrote: > >       echo modified >> a.txt > >       git add a.txt > >       git checkout -- a.txt           (1) > > > >       git checkout HEAD -- a.txt      (2) > > > > > > (1) This will do nothing to your file 'a.txt' in your workdir because > >     the index and the workdir are identical > > > > (2) This will reset your file to the state before you run that bogus > >     echo modified >> a.txt   comand > > I still do not understand what index is. > 1. is index an replica of the committed tree > 2. is index only transient in that its content will be reset once >   committed? > 3. or other ? I think index is HEAD or a revision hash. Am I correct ?

Am I correct ? HEAD is a reference to a branch name: $ cat .git/HEAD ref: refs/heads/master $ The branch name is a reference to a commit: $ cat .git/refs/heads/master a80aad7b85fc560451e07792d64ab6cb15a39914 $ The index is what will be committed by 'git commit'. -- Nicolas Sebrecht ``` ## Aaron Gray, 2009-05-31 19:31 Subject: Re: Resetting working files Message-ID: <34D6982455BA4A7E9F5D2D467DC4A55C@HPLAPTOP> URL: https://gitlist.dev/e/34D6982455BA4A7E9F5D2D467DC4A55C%40HPLAPTOP In-Reply-To: <20090531173932.GA13856@vidovic> ``` > The 31/05/09, Aaron Gray wrote: > >> > I still do not understand what index is. >> > 1. is index an replica of the committed tree >> > 2. is index only transient in that its content will be reset once >> > committed? >> > 3. or other ? >> >> I think index is HEAD or a revision hash.

Obviously alot more to learn about GIT, hopefully the O'Reilly book will clue me up as I am still getting problems with using GIT properly.

The pointers to a commit in git are allowed to be indirect by referencing other pointers. ```
