Merge a branch to main

Next, let’s merge the branch you just created (i.e., issue1) along with its commit to main.

To merge our commits into the main branch, we must first switch to the main branch.

$ git checkout main
Switched to branch 'main'

Before merging, open the myfile.txt file and check the content of the file. You’ll see this:

As you’ll see, the change added on issue1 we made in the previous step isn’t included in the myfile.txt file on the main branch.

When you use the git merge command, the specified commit will merge with the active branch. Using the following command, we can now merge.

$ git merge issue1
Updating 1257027..b2b23c4
Fast-forward
myfile.txt |    1 +
1 files changed, 1 insertions(+), 0 deletions(-)

The position of the main branch will now move over to that of issue1, executing a fast-forward merge.

Finally, let’s confirm the content of the myfile.txt file. Open myfile.txt, and you will see the new line we committed to the issue1 branch is now on the main branch.
