Git How to remove file from index without deleting files from any repository

Question

When you use  git rm --cached myfile   it doesn t delete from the local filesystem  which is the goal  But if you ve already versioned and committed the file  pushed it to a central repository  and pulled it into yet another repository before using the command  it will delete the file from that system   Is there a way to just remove the file from versioning without deleting it from any filesystem   Edit  Clarified  I hope

My solution is to pull on the other working copy and then do:

git log --pretty="format:" --name-only -n1 | xargs git checkout HEAD^1

which says get all the file paths in the latest comment, and check them out from the parent of HEAD. Job done.

To remove the file from the index  use   git reset myfile   This should not affect your local copy or anyone else s

The above solutions work fine for most cases  However  if you also need to remove all traces of that file  ie sensitive data such as passwords   you will also want to remove it from your entire commit history  as the file could still be retrieved from there   Here is a solution that removes all traces of the file from your entire commit history  as though it never existed  yet keeps the file in place on your system   https   help github com articles remove-sensitive-data   You can actually skip to step 3 if you are in your local git repository  and don t need to perform a dry run   In my case  I only needed steps 3 and 6  as I had already created my  gitignore file  and was in the repository I wanted to work on   To see your changes  you may need to go to the GitHub root of your repository and refresh the page  Then navigate through the links to get to an old commit that once had the file  to see that it has now been removed  For me  simply refreshing the old commit page did not show the change   It looked intimidating at first  but really  was easy and worked like a charm    -

Had the very same issue this week when I accidentally committed  then tried to remove a build file from a shared repository  and this   http   gitready com intermediate 2009 02 18 temporarily-ignoring-files html  has worked fine for me and not mentioned so far   git update-index --assume-unchanged  lt file gt    To remove the file you re interested in from version control  then use all your other commands as normal   git update-index --no-assume-unchanged  lt file gt    If you ever wanted to put it back in   Edit  please see comments from Chris Johnsen and KPM  this only works locally and the file remains under version control for other users if they don t also do it  The accepted answer gives more complete correct methods for dealing with this  Also some notes from the link if using this method      Obviously there   s quite a few caveats that come into play with this    If you git add the file directly  it will be added to the index    Merging a commit with this flag on will cause the merge to fail   gracefully so you can handle it manually

After doing the git rm --cached command  try adding myfile to the  gitignore file  create one if it does not exist    This should tell git to ignore myfile   The  gitignore file is versioned  so you ll need to commit it and push it to the remote repository

I do not think a Git commit can record an intention like    stop tracking this file  but do not delete it      Enacting such an intention will require intervention outside Git in any repositories that merge  or rebase onto  a commit that deletes the file     Save a Copy  Apply Deletion  Restore  Probably the easiest thing to do is to tell your downstream users to save a copy of the file  pull your deletion  then restore the file  If they are pulling via rebase and are    carrying    modifications to the file  they will get conflicts  To resolve such conflicts  use git rm foo conf  amp  amp  git rebase --continue  if the conflicting commit has changes besides those to the removed file  or git rebase --skip  if the conflicting commit has only changed to the removed file    Restore File as Untracked After Pulling a Commit That Deletes It  If they have already pulled your deletion commit  they can still recover the previous version of the file with git show   git show   1  foo conf  gt foo conf   Or with git checkout  per comment by William Pursell  but remember to re-remove it from the index     git checkout   1  -- foo conf  amp  amp  git rm --cached foo conf   If they have taken other actions since pulling your deletion  or they are pulling with rebase into a detached HEAD   they may need something other than   1   They could use git log -g to find the commit just before they pulled your deletion     In a comment  you mention that the file you want to    untrack  but keep    is some kind of configuration file that is required for running the software  directly out of a repository    Keep File as a    Default    and Manually Automatically Activate It  If it is not completely unacceptable to continue to maintain the configuration file s content in the repository  you might be able to rename the tracked file from  e g   foo conf to foo conf default and then instruct your users to cp foo conf default foo conf after applying the rename commit  Or  if the users already use some existing part of the repository  e g  a script or some other program configured by content in the repository  e g  Makefile or similar   to launch deploy your software  you could incorporate a defaulting mechanism into the launch deploy process   test -f foo conf    test -f foo conf default  amp  amp      cp foo conf default foo conf   With such a defaulting mechanism in place  users should be able to pull a commit that renames foo conf to foo conf default without having to do any extra work  Also  you avoid having to manually copy a configuration file if you make additional installations repositories in the future   Rewriting History Requires Manual Intervention Anyway     If it is unacceptable to maintain the content in the repository then you will likely want to completely eradicate it from history with something like git filter-branch --index-filter      This amounts to rewriting history  which will require manual intervention for each branch repository  see    Recovering From Upstream Rebase    section in the git rebase manpage   The special treatment required for your configuration file would be just another step that one must perform while recovering from the rewrite    Save a copy of the configuration file  Recover from the rewrite  Restore the configuration file      Ignore It to Prevent Recurrence  Whatever method you use  you will probably want to include the configuration filename in a  gitignore file in the repository so that no one can inadvertently git add foo conf again  it is possible  but requires -f --force   If you have more than one configuration file  you might consider    moving    them all into a single directory and ignoring the whole thing  by    moving    I mean changing where the program expects to find its configuration files  and getting the users  or the launch deploy mechanism  to copy move the files to to their new location  you obviously would not want to git mv a file into a directory that you will be ignoring
