How to use grep with o option and [ ]?

Question

I am trying to figure how to use grep with -o and [ ] brackets. So i have a line that says ``` ``` I basically want `name="test 2"` so i tried: ``` grep -o 'name="[*]"' grep -o 'name="*"' ``` I mostly get `name=""`. Also a link to a page that shows lots of examples would be great also.

Accepted Answer

You probably need

```
grep -o 'name="[^"]\+"' your_file
```

Output:

```
name="test"
name="testa"
name="1test2"
name="testb"
```

And this is equivalent:

```
grep -Eo 'name="[^"]+"' your_file
```
