To install Ubuntu 16.04.3 on my laptop, I used my 8GB pen-drive. The installation of OS has done now. I want to clean this bootable pen-drive to use it normally.I want to clean it completely like we do in GUI.

The easiest way is with dd but you must be careful to specify the device exactly:

dd if=/dev/zero of=/dev/sdX count=1 bs=512

This will erase the partition table / MBR (Master Boot Record) making the pendrive empty and ready for reformatting.

Replace sdX with sdc, sde, etc. matching your pendrive letter revealed by lsblk.

Format your pen-drive using 'Disks' utility in Ubuntu, then you can use it normally. Here is the link for the same : How to format a USB flash drive?

An easy and safe method is to restore the USB pendrive to a standard storage device with mkusb. It will wipe the current partition table and create an MSDOS partition table and a partition with a FAT32 file system.

See the following links,
