I'm processing a manpage in nroff format with awk to extract the options to each command... I figured out that the options start with `\fB`, followed by the actual option, and maybe `\fP` and option arguments and so on...

Example:

```
\fB\-\-author\fR

```

I started writing an awk-script, specifing `FS = "\fB"` ... well, it didn't work... I tried to escape the `\`, switching to `FS = "\\fB"` but didn't work either... what am I doing wrong?

---

This is my script:

```
BEGIN {
    FS = "\\f." # "\\\\f." didn't work either
}

{
    print $2
}

```

This is the input

> 
> \fB-o\fP
> 
> 
> 

Where I want $2 to be -o. But it just won't work.
