By default, git will not track files. You need to tell git which files you want to track. Create a file named example.txt, and add Hello World to the file.
The git status command will show that example.txt is not being tracked.
$ git status . . . Untracked files: . . . example.txt
Use the git add filename command to stage a file for commitment. In this example, the example.txt file is being staged.
$ git add example.txt
The git status command will now show that example.txt is ready to be committed.
$ git status . . . Changes to be committed: . . . new file: example.txt
Use the git commit command with the -m (message) option to commit a file. In this example,1 file changed is displayed.
$ git commit -m 'First Commitment' . . . 1 file changed, 1 insertion(+) create mode 100644 example.txt
The git log command will show the First Commitment.
$ git log Author: John Doe <firstname.lastname@example.org> Date: Tue May 30 20:26:36 2017 -0500 First commitment
Let's make a change to example.txt. The text How are you today is added to example.txt.
When a change is made to a staged or commited file, the file will be listed as modified in the git status command.
$ git status . . . modified: example.txt
After staging and commiting example.txt again, the git log command will show the two commitments.
$ git log . . . Second commitment . . . First commitment
Working with numerous files
Let's say you have numerous files that you want to stage and commit. Instead of staging and commiting each file one by one, the -a option or a single period can be used to stage all of the files in the directory. For example, let's say C:\Users\john.doe\Sample contains example1.txt, example2.txt and example3.txt. The git add -A, or git add --all, or git add . command can be used to stage all of the files in the directory.
$ git add .
The git commit command will commit all three files that have been staged.
$ git commit -m 'First Commitment' . . . 3 files changed, 3 insertion(+) create mode 100644 example1.txt create mode 100644 example2.txt create mode 100644 example3.txt
There will typically be some files you do not want to stage and commit. To exclude files, create the .gitignore file.
$ touch .gitignore
Let's say you do not want to stage and commit files ending in .log. Add the following to the .gitignore file. You will probably want to stage and commit the .gitignore file.
Directories can be ignore by entering the directory name followed by a forward slash.
