Git：git logコマンドでコミット履歴をグラフで表示する方法

git logコマンドでコミット履歴をグラフで表示する方法

git logコマンドでコミット履歴をグラフで表示するには--graphオプションを指定します。

オプションの説明

 --graph
     Draw a text-based graphical representation of the commit history on the left hand side of the output. This may cause extra lines to be printed in between
     commits, in order for the graph history to be drawn properly. Cannot be combined with --no-walk.

     This enables parent rewriting, see History Simplification above.

     This implies the --topo-order option by default, but the --date-order option may also be specified.
 --oneline
     This is a shorthand for "--pretty=oneline --abbrev-commit" used together.
 -<number>, -n <number>, --max-count=<number>
     Limit the number of commits to output.

--graphオプションを指定した場合（-nオプションは出力するコミット数の指定、--onelineオプションは一行で出力するオプション）

$ git log --graph -n 10 --oneline
