When using linux system, it inevitable that we will using terminal, maybe the one we mostly using is sudo. sudo nano /etc/..., sudo apt update, sudo pacman -Syu and other command that need privileged permission. Then instead using plain sudo, we can make it more beauty by add some template file to it.

Ok, (g)root let me pass.

First we need enable lecture, what is lecture?

We should be seeing once at beginning or so then it not shown again, but we need to make this always shown because we want to see our beautified sudo every time

Add this line to /etc/sudoers

Defaults        lecture=always

Then when you execute sudo again, the lecture will show.

Then we append another line

Defaults       lecture_file=/etc/sudo_lecture.txt

/etc/sudo_lecture.txt will be the file that we modify as we wish.

Some sample of it:

┌──────────────────────────────────────────┐
│                                          │
│ mmmm                                     │
│ #   "m  mmm   m mm    mmmm   mmm    m mm │
│ #    # "   #  #"  #  #" "#  #"  #   #"  "│
│ #    # m"""#  #   #  #   #  #""""   #    │
│ #mmm"  "mm"#  #   #  "#m"#  "#mm"   #    │
│                       m  #               │
│                        ""                │
└──────────────────────────────────────────┘

Using toilet command to generate sudo_lecture

$ sudo sh -c 'toilet -f bubble --metal "Be careful with sudo" > /etc/sudo_lecture.txt'
# invalidates the user's cached credentials #
$ sudo -K
$ sudo -i

My personal favorite:

       \^V//
       |. .|    I AM (G)ROOT!
     - \ - / _
      \_| |_/
        \ \
      __/_/__
     |_______|   With great power comes great responsibility.
      \     /    Use sudo wisely.
       \___/
