Three ways to cancel git add command

In the process of using Git for version control, we often need to use the git add command to add modified files to the staging area for final submission to the repository. However, before adding files, sometimes we may make mistakes, such as adding unnecessary files to the staging area, or adding wrong files. How to deal with it at this time? This article will introduce three methods to cancel the git add command.

Method 1: Use the git reset command to cancel the temporary storage

In Git, the git reset command can be used to reset the temporary storage area or undo a commit. When we use the git add command, the file will be added to the staging area. If we want to cancel this operation, we can use the following command:

git reset <file></file>

Among them, means to cancel the staging area file name, you can also use wildcards to unstage multiple files. For example, to cancel the temporary storage of all files, you can use the following command:

git reset .

It should be noted that this method only cancels the add operation, and the file modifications are not deleted. If you need to completely undo the modification, you also need to use the git checkout command.

Method 2: Use the git rm command to cancel the temporary save

In addition to using the git reset command, you can also use the git rm command to cancel the temporary save. This command is used to delete files and add the deletion operation to the staging area. If we use this command to delete a file that was mistakenly added to the temporary storage area, we can cancel the addition and deletion operations at the same time. Use the following command:

git rm --cached <file></file>

Among them, --cached means to only delete files from the temporary storage area without deleting files in the workspace. The file names that need to be canceled can be replaced with wildcard characters. For example, to cancel the temporary storage of all files, you can use the following command:

git rm --cached .

Method 3: Use the git restore command to cancel the temporary storage

In Git Version 2.23 introduces a new command git restore, which is used to restore files in the workspace and can also be used to cancel the temporary storage of files. Use the following command:

git restore --staged <file></file>

Among them, --staged means to restore the file from the staging area to the work area. Files that need to be canceled can be replaced with wildcards. For example, to cancel the temporary storage of all files, you can use the following command:

git restore --staged .

It should be noted that if the contents of the files in the temporary area and the work area are different , then canceling the temporary operation will not restore the content of the file. You need to use the git checkout command or other methods to restore the file content to its previous state.

To sum up, Git provides a variety of methods to cancel the git add command. This can be achieved using the git reset, git rm and git restore commands. It is necessary to choose the appropriate method according to the specific situation in order to achieve better version control and management.
