如何使用 git 忽略对跟踪文件的新更改？ [重复]

Question

当我运行 git status 时：

$ git status
# On branch master
# Changes not staged for commit:
#   (use "git add/rm <file>..." to update what will be committed)
#   (use "git checkout -- <file>..." to discard changes in working directory)
#
#       modified:   .gitignore
#       modified:   .project
#       modified:   reports/images/2014-03.png
#       modified:   reports/images/graph-2014-03.bmp
#       deleted:    reports/phpbmp/cache/0/02/027/0270/phpThumb_cache_portal.gep.co.za_src02707010e1e50bc80594

#
# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#       README.MD
#       reports/phpbmp/cache/9/
no changes added to commit (use "git add" and/or "git commit -a")

我意识到我不希望跟踪对以下文件的更改：

.project
reports/images/*.png
reports/images/*.bmp
reports/phpbmp/cache/*

所以我将这些文件添加到

.gitignore

如何从当前工作目录中删除

Changes not staged for commit

下的文件？

Answer 1

如果我理解得很好，你希望

filename

位于 git 存储库中。但是，您不希望收到有关

filename

的新更改的通知。您可以使用以下命令来执行此操作：

git update-index --assume-unchanged <filename>

如果您想再次开始跟踪更改，请运行以下命令：

git update-index --no-assume-unchanged <filename>

附加信息：编辑 .gitignore 只会忽略文件，因此它们不会被添加到 git 存储库中。但是，已经跟踪的文件不会被忽略。

Answer 2

文件已被跟踪，现在您想忽略这些文件。

git rm --cached filename 
echo "filename" >> .gitignore
git add .gitignore
git commit -m 'Removes filename file and adds it to gitignore.'
