The git add command is used to add changes in a file to the staging area (also called the index) in Git. The staged changes are then ready to be committed to the repository. The basic syntax for the git add command is: $ git add <file>
Where <file> can be a specific file or a pattern to match multiple files. For example:
$ git add . # adds all changes in all files in the current directory and its subdirectories
$ git add file.txt # adds changes in file.txt
$ git add “*.txt” # adds changes in all .txt files
You can also use git add -A or git add --all to stage all changes, including additions, deletions, and modifications, in all files in the repository.
It is important to note that git add only stages changes; it does not make a permanent change in the repository. To make the change permanent, you need to commit the staged changes using the git commit command.
Git add All
The git add -A or git add --all command is used to stage all changes in the working tree, including new files, modified files, and deleted files. The basic syntax of the command is: git add -A or git add –all
This command stages all changes in the working tree, regardless of whether they have been previously staged or not. If you have newly created files, modified files, or deleted files, using git add -A will stage all of those changes and prepare them to be committed to the repository.
Git Removing Files from the Staging Area
To remove a file from the Git staging area, you can use the git reset command. The basic syntax is: git reset <file>
where <file> is the name of the file you want to remove from the staging area. This command un-stages the file and leaves it in the working directory. You can then make further changes to the file before re-adding it to the staging area and committing it.
If you want to un-stage multiple files at once, you can list them after the git reset command: git reset file1 file2 file3
If you want to un-stage all changes, you can use the git reset command with the --hard option: git reset –hard
This command discards all changes in the working directory and the staging area, and resets the repository to the latest commit. Be careful when using this option, as it can permanently destroy changes that have not been committed to the repository.
Git Add all New and Updated Files Only
To add all new and updated files only in Git, you can use the command git add -u. The -u option stands for “update” and it adds changes to files that have already been tracked by Git. This command will not stage new files that have not yet been tracked. If you want to stage both new and modified files, you can use git add . which will stage all changes in the current directory and its subdirectories.
Git Add all Modified and Deleted Files
To add all modified and deleted files in Git, you can use the command git add -u. The -u option stands for “update” and it stages changes to files that have already been tracked by Git, including deletions. This command will not stage new files that have not yet been tracked. If you want to stage all changes, including new files, you can use git add . which will stage all changes in the current directory and its subdirectories.
Git Add Files by Wildcard
The Git add command allows you to add files to the Git staging area by using wildcards. Wildcards are characters that match multiple files at once. For example, you can use the * symbol to match all files with a certain extension or pattern.
To add all files with a certain extension, you can run the following command: git add *.extension
Where *.extension is the wildcard pattern you want to match.
Similarly, you can add all files within a certain directory by using the following command: git add path/to/directory/*
This will add all files within the specified directory to the Git staging area.
Git Undo Add
The “git reset” command can be used to undo an add. For example, if you’ve added a file but haven’t committed it yet, you can use the command “git reset <file>” to remove the file from the staging area. This will effectively undo the add, and the file will no longer be staged for commit.
