+# Get The Name Of The Current Branch
+
+There are a couple ways of doing this. If you are on Git 2.22+, then the
+`git-branch` porcelain command now supports a flag for this.
+
+```bash
+$ git branch --show-current
+main
+```
+
+If you are on an older version of Git or looking for a plumbing command that is
+more appropriate for scripting, then `git-rev-parse` is what you're looking
+for.
+
+```bash
+$ git rev-parse --abbrev-ref HEAD
+main
+```
