```
### Graphs
### Show all commits in the current branch’s history The --graph option draws an ASCII graph representing the branch structure of the commit history. This is commonly used in conjunction with the --oneline and --decorate commands to make it easier to see which commit belongs to which branch:
```bash
$ git log
commit 784ae2e2d10720c23eb7cebdf8386ef2157fe628 (HEAD -> master)
Author: unknown <Admin@FOR209-03.irisib.lan>
Date: Thu Apr 1 12:11:34 2021 +0200
First Commit > $ git log --graph --oneline --decorate
```

Tig allows you to browse changes in a Git repository and can additionally act as a pager for output of various Git commands. When used as a pager, it will display input from stdin and colorize it.
