Here's a useful trio to know about to help you search things in git:
1. `git show <commit>`
2. `git log --grep='<regexp>'`
3. `git grep '<regexp>' [commit]`
## 1. `git show <commit>`
Show a specific commit and it's diff:
```shell
git show
# shows the latest commit
git show <commit>
# shows an specific <commit>
git show v1.2
# shows commit tagged with v1.2
```
## 2. `git log --grep='<regexp>'`
Search through the commit messages:
```shell
git log --grep='refactor'
```
## 3. `git grep '<regexp>' [commit]`
Search content in git history:
```shell
git grep 'TODO'
# search the repository for the "TODO" string
git grep 'TODO' $(git rev-list --all)
# search the whole history for "TODO" string
```
And if you find an occurrence of the regexp in a specific commit and you want to
browse the repository in that point in time, you can
[use git checkout for that][0].
