+title: Search in git

+
+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].
