4.3 Committing Multiple Files

The staging area can hold changes from any number of files that you want to commit as a single snapshot.

1. Add some text to guacamole.md noting the rough price of the ingredients.
2. Create a new file groceries.md with a list of products and their prices for different markets.
3. Add changes from both files to the staging area, and commit those changes.

Solution

First we make our changes to the guacamole.md and groceries.md files:

$ nano guacamole.md
$ cat guacamole.md

# Ingredients
- avocado (1.35)
- lime (0.64)
- salt (2)

$ nano groceries.md
$ cat groceries.md

# Market A
- avocado: 1.35 per unit.
- lime: 0.64 per unit
- salt: 2 per kg

Now you can add both files to the staging area. We can do that in one line:

$ git add guacamole.md groceries.md

Or with multiple commands:

$ git add guacamole.md
$ git add groceries.md

Now the files are ready to commit. You can check that using git status. If you are ready to commit use:

$ git commit -m "Write prices for ingredients and their source"
