# Unshadow

### Unshadow

If you have found the passwd and shadow files under linux you can combine them on a file using **unshadow** command and then crack them using **John**. 

```
unshadow passwd.txt shadow.txt 
unshadow passwd.txt shadow.txt > unshadow.txt
john --rules --wordlist=/usr/share/wordlists/rockyou.txt unshadow.txt 
```
