+# Open File To Specific Line In Browser
+
+Often one of the best ways to point a teammate to a line of code is to share a
+GitHub link to a specific file and line number. Sometimes even a specific
+commit.
+
+For the longest time I would manually open GitHub, navigate to that file, and so
+forth. The `gh` CLI supports this with the `browse` subcommand and it takes way
+less time if you already have the repo in your local filesystem.
+
+For instance, if I want to point you to line 11 of the `zshrc.local` file in my
+`dotfiles` repo, I can run the following command:
+
+```bash
+$ gh browse zshrc.local:11
+```
+
+That would open a browser tab to
+[https://github.com/jbranchaud/dotfiles/blob/main/zshrc.local?plain=1#L11](https://github.com/jbranchaud/dotfiles/blob/main/zshrc.local?plain=1#L11).
+
+If I wanted a range of lines, I could change it from `11` to, say, `11-27`:
+
+```bash
+$ gh browse zshrc.local:11-27
+```
+
+And I would see this in the browser --
+[https://github.com/jbranchaud/dotfiles/blob/main/zshrc.local?plain=1#L11-L27](https://github.com/jbranchaud/dotfiles/blob/main/zshrc.local?plain=1#L11-L27).
+
+Both of these URLs are pointing to the `main` branch. If I instead want to
+reference a specific commit, I can use the `--commit` flag.
+
+```bash
+$ gh browse zshrc.local:11-27 --commit=f2f9e78d4fc784643f725c88f7a5a7a077e7f261
+```
+
+I grabbed that from the latest commit in `git log`. That opens to
+[https://github.com/jbranchaud/dotfiles/blob/f2f9e78d4fc784643f725c88f7a5a7a077e7f261/zshrc.local?plain=1#L11-L27](https://github.com/jbranchaud/dotfiles/blob/f2f9e78d4fc784643f725c88f7a5a7a077e7f261/zshrc.local?plain=1#L11-L27).
+
+Another way of doing that would be to use `git rev-parse HEAD`:
+
+```bash
+$ gh browse zshrc.local:11-27 --commit=$(git rev-parse HEAD)
+```
+
+See `gh browse --help` for more details.
