git-stage: Add a file to the index.
$ git stage ${filename}
try on your machine
The command "git stage" is not a valid Git command. The correct command to stage a file for commit in Git is "git add".
If you are referring to the "git add" command with the placeholder "${filename}", it is used to add a specific file to the staging area in Git. The staging area in Git is a place where you can prepare and organize your changes before committing them. Once a file is staged, it is marked as ready to be included in the next commit.
To use the "git add" command, you would replace "${filename}" with the actual name of the file you want to stage. For example, if you have a file named "index.html" that you want to stage, you would execute the command "git add index.html". This will add the "index.html" file to the staging area.
