It's a lot of trouble, and I'll write it quickly and briefly. It's a memorandum, it's almost just for me

// .open bashrc
$ vim .bashrc

↓

//Move to the first
# prompt change
export PS="\[e[31m\]FuckMyLife\[\e[0m]: \w \$ "

↓

$ . .bashrc

that's all

Supplement

\ [e [31m ] ~ will be red after this ] \ e [0m] to restore the color

\ w is the current directory \ $ Is just like I saw it.
