It is not that easy for a niewbie. Why do not use GUI tools? – Pilot6 Aug 18 '15 at 13:14

If you make a mistake, you can format your HDD. There will be no warning. – Pilot6 Aug 18 '15 at 13:24
    
oh right, hahahaha thanks for the warning :) – warrior Aug 18 '15 at 13:32
    
This question is NOT a duplicate (at least not the one marked). That one asks for a GUI, and this one for a command line solution... – Calimo Aug 19 '15 at 10:06
    
@Calimo The other question has been broadened to include command-line solution, just the wording was never removed. – Seth♦ Aug 20 '15 at 1:33

  • First, you have to find out which device (/dev/sd??) your USB stick is. Therefore look at the output of 

    sudo fdisk -l

  • After that unmount the device/partition (if necessary) by running

    sudo umount /dev/sd??

    Make sure you replaced ?? with the correct device/partition name from the previous output.

  • To format The partition as FAT32 use

    sudo mkdosfs -F 32 -I /dev/sd??

    Again replace ?? with your respective letters.

Be careful that if you enter the wrong device name, you might also accidentally format your hard disk!

You can also do

    sudo -s

and you don't have to put "sudo" in front of everything!

sudo chmod 777 /dev/sd?? – madzohan Mar 25 '17 at 16:54
    
Have a SCRIPT for the whole shebang would be nice (with some sanity checks, that it's a a) USB b) removable device c) no larger than 32 GB d) unrelated to the usual pack like /, /boot, etc. as an extra precaution) – Frank Nocke Sep 16 '17 at 12:27
