      What type of word list are you looking for? Cause crunch doesn’t generate names nor addresses nor commonly used passwords for you. What it does is to generate character sets from 000 to 999 or AAA to ZZZ or a mixture of them.

    i need help . how to save the dictionnary to my hard disk ?bcz every time i write these commands it save on root wich is 1.9 gb so please help

      Hello elias el hourany,

      What you have to do is to redirect the output file’s directory. If your root hard drive is out of free space, use an external hard drive. Make sure you know what is the hard drive name for your external. It could have sdb1, sdb2 or something along that name.
