- How to make Git “forget” about a file that was tracked but is now in .gitignore? 24 answers
I have an already initialized Git repository that I added a .gitignore file to. How can I refresh the file index so the files I want ignored get ignored?
回答1:
To untrack a single file that has already been added/initialized to your repository, i.e., stop tracking the file but not delete it from your system use: git rm --cached filename
To untrack every file that is now in your .gitignore:
First commit any outstanding code changes, and then, run this command:
git rm -r --cached .
This removes any changed files from the index(staging area), then just run:
git add .
Commit it:
git commit -m ".gitignore is now working"
To undo git rm --cached filename, use git add filename.
Make sure to commit all your important changes before running
git add .Otherwise, you will lose any changes to other files.

If you are trying to ignore changes to a file that's already tracked in the repository (e.g. a dev.properties file that you would need to change for your local environment but you would never want to check in these changes) than what you want to do is:
git update-index --assume-unchanged <file>
If you wanna start tracking changes again
git update-index --no-assume-unchanged <file>
See git-update-index(1) Manual Page.
Also have a look at the skip-worktree and no-skip-worktree options for update-index if you need this to persist past a git-reset (via)
Update: Since people have been asking, here's a convenient (and updated since commented on below) alias for seeing which files are currently "ignored" (--assume-unchanged) in your local workspace
$ git config --global alias.ignored = !git ls-files -v | grep "^[[:lower:]]"

回答4:
Yes - .gitignore system only ignores files not currently under version control from git.
I.e. if you've already added a file called test.txt using git-add, then adding test.txt to .gitignore will still cause changes to test.txt to be tracked.
You would have to git rm test.txt first and commit that change. Only then will changes to test.txt be ignored.

Remove trailing whitespace in .gitignore
Also, make sure you have no trailing whitespace in your .gitignore. I got to this question because I was searching for an answer, then I had a funny feeling I should open the editor instead of just cat'ing .gitignore. Removed a single extra space from the end and poof it works now :)
回答6:
i followed these steps
git rm -r --cached .
git add .
git reset HEAD
after that, git delete all files (*.swp in my case) that should be ignoring.
回答7:
If you want to stop tracking file without deleting the file from your local system, which I prefer for ignoring config/database.yml file. Simply try:
git rm --cached config/database.yml
# this will delete your file from git history but not from your local system.
now, add this file to .gitignore file and commit the changes. And from now on, any changes made to config/database.yml will not get tracked by git.
$ echo config/database.yml >> .gitignore
Thanks

Complex answers everywhere!
Just use the following
git rm -r --cached .
It will remove the files you are trying to ignore from the origin and not from the master on your computer!
After that just commit and push!
回答9:
To remove just a few specific files from being tracked:
git update-index --assume-unchanged path/to/file
If ever you want to start tracking it again:
git update-index --no-assume-unchanged path/to/file
回答10:
As dav_i says, in order to keep the file in repo and yet removing it from changes without creating an extra commit you can use:
git update-index --assume-unchanged filename

Not knowing quite what the 'answer' command did, I ran it, much to my dismay. It recursively removes every file from your git repo.
Stackoverflow to the rescue... How to revert a "git rm -r ."?
git reset HEAD
Did the trick, since I had uncommitted local files that I didn't want to overwrite.
回答12:
There is another suggestion maybe for the slow guys like me =) Put the .gitignore file into your repository root not in .git folder. Cheers!
回答13:
None of the answers worked for me.
Instead:
- Move the file out of the git-controlled directory
- Check the removal into git
- Move the file back into the git-controlled directory
After moving the file back, git will ignore it.
Works with directories too!
回答14:
another problem I had was I placed an inline comment.
tmp/* # ignore my tmp folder (this doesn't work)
this works
# ignore my tmp folder
tmp/
回答15:
If the files are already in version control you need to remove them manually.
回答16:
Thanks to your answer, I was able to write this little one-liner to improve it. I ran it on my .gitignore and repo, and had no issues, but if anybody sees any glaring problems, please comment. This should git rm -r --cached from .gitignore:
cat $(git rev-parse --show-toplevel)/.gitIgnore | sed "s//$//" | grep -v "^#" | xargs -L 1 -I {} find $(git rev-parse --show-toplevel) -name "{}" | xargs -L 1 git rm -r --cached
Note that you'll get a lot of fatal: pathspec '<pathspec>' did not match any files. That's just for the files which haven't been modified.

I have found a weird problem with .gitignore. Everything was in place and seemed correct. The only reason why my .gitignore was "ignored" was, that the line-ending was in Mac-Format (\r). So after saving the file with the correct line-ending (in vi using :set ff=unix) everything worked like a charm!
回答18:
One other problem not mentioned here is if you've created your .gitignore in Windows notepad it can look like gibberish on other platforms as I found out. The key is to make sure you the encoding is set to ANSI in notepad, (or make the file on linux as I did).

回答19:
On my server linux server (not true on my local dev mac), directories are ignored as long as I don't add an asterisk:
www/archives/*
I don't know why but it made me loose a couple of hours, so I wanted to share...
回答20:
One thing to also keep in mind if .gitignore does not seem to be ignoring untracked files is that you should not have comments on the same line as the ignores. So this is okay
# ignore all foo.txt, foo.markdown, foo.dat, etc.
foo*
But this will not work:
foo* # ignore all foo.txt, foo.markdown, foo.dat, etc.
.gitignore interprets the latter case as "ignore files named "foo* # ignore all foo.txt, foo.markdown, foo.dat, etc.", which, of course, you don't have.
回答21:
If you need to stop tracking a lot of ignored files, you can combine some commands:
git ls-files -i --exclude-standard | xargs -L1 git rm --cached
This would stop tracking the ignored files. If you want to actually remove files from filesystem, do not use the --cached option. You can also specify a folder to limit the search, such as:
git ls-files -i --exclude-standard -- ${FOLDER} | xargs -L1 git rm
