You can read down, down.

Search the commit log

Use the "--grep" option to search the commit log for commit messages. Enter the character string you want to search for in the character string.

git log --grep string

You can retrieve the commit log that matches your search.

I want to know the commit ID immediately before the matched commit ID

Sometimes you want to know the commit ID just before the matched commit ID.

In such a case, you can actually specify the previous commit ID with the notation "Commit ID ^". "Commit ID ^^" can be specified two times before, and "Commit ID ^^^" can be specified three times before.

Let's say the commit IDs that match your search are:


Let's say you want to see the difference from the previous one. Using the notation "commit ID ^", do the following:

git diff be401600433693794eecbc65ed4b9e787902ed9a ^ be401600433693794eecbc65ed4b9e787902ed9a

When do you use git log?

I will introduce the scene where git log is used.

If you want to check after committing with git commit.

If you want to check what kind of branch the branch created by git branch is, you want to use git log to start the commit.

I want to see the beginning of the commit with git log even when switching branches with git checkout.

You can also use git reset to check the commit ID when returning a commit to a certain state.

In addition, if you want to check the commit ID, use it each time.
