```

## Filtering options

```bash
--hs/ss "regex" #Hide/Show
#Simple example, match a string: "Invalid username"
#Regex example: "Invalid *"

--hc/sc CODE #Hide/Show by code in response
--hl/sl NUM #ide/Show by number of lines in response
--hw/sw NUM #ide/Show by number of words in response

```

## Output options

```bash
wfuzz -e printers #Prints the available output formats

```

### Encoders options

```bash
wfuzz -e encoders #Prints the available encoders

In order to use a encoder, you have to indicate it in the **"-w"** or **"-z"** option.

Examples:

```bash
-z file,/path/to/file,md5 #Will use a list inside the file, and will trnasform each value into its md5 hash before sending it
-w /path/to/file,base64 #Will use a list, and transforms to base64
-z list,each-element-here,hexlify #Inline list and to hex before sending values
```
