Developers use terminal all the time because it is effective than graphical user interfaces (GUI). Therefore, I spend my time on my lovely terminal, but the problem is length of hostname. I use default size which is 80x24. berkhans-thinkpad-t460 has 22 characters… Now, you can imagine that is why important for me.

I will just share simple snippet that will help you to remove that hostname part.

if [ "$color_prompt" = yes ]; then

    PS1='\u:\w\$ '

unset color_prompt force_color_prompt

After you restart your terminal, you will have this
