How to start ubuntu in command line interface

I want to set my ubuntu PC to command line interface. I don't want to start the desktop manager.

GRUB_CMDLINE_LINUX=""

3. change to:

GRUB_CMDLINE_LINUX_DEFAULT="text"
GRUB_CMDLINE_LINUX="3"

 4. run: sudo update-grub

5. Done. Every time we start the PC, it doesn't start the desktop manager automatically. If we want to start the desktop manager, run: sudo init 5
