untrack file

This will tell git you want to start ignoring the changes to the file

git update-index --assume-unchanged path/to/file

When you want to start keeping track again

git update-index --no-assume-unchanged path/to/file

This command will cause git to untrack your directory and all files under it without actually deleting them:

git rm -r --cached <your directory>

The -r option causes the removal of all files under your directory.

The --cached option causes the files to only be removed from git's index, not your working copy. By default git rm <file> would delete <file>.

git reset

Head / Index /Working copy

1. Head ===> git commit 之后的文件

2. Index ===> git add 之后的文件

3. working copy ==>工作区文件

git reset --soft == (reset 1) 只改动Head，其余保留。

git reset(default) == (reset 1,2) 变动Head与Index, 保留工作区改动。

git reset --hard == (reset 1,2,3) 全部撤销。
