I needed to make a file in a repository non-readable and non-writable:

```
sudo chmod 101 file1.sh

```

when you list it it looks like this:

```
$ ls -la file1.sh
---x-----x 1 cardamom cardamom 13 Nov 16 16:52 file1.sh

```

`git add` will not work:

```
error: open("file1.sh"): Permission denied
error: unable to index file file1.sh
fatal: updating files failed

```

and adding it to `.gitignore` does not cause it to be ignored.  

I don't really need to track it, but would be good to not have it pop up every time `git status` is typed in. 

How does one either add it to the repo or tell git to ignore it?
