If you want a more simple banner you can use something like pyfiglet as shown in this tutorial https://www.devdungeon.com/content/create-ascii-art-text-banners-python

Something else I came up with today while I was fucking around with writing a reverse TCP shell and server. I was thinking it could be fun to just customize the command prompt and add in some of my own commands. I really haven't done much with this as I have some other projects take priority.

#!/usr/bin/python3
import threading
import time
from queue import Queue
import socket
import sys
import os
import subprocess


def Pepe():
    while 1:
        print('Pepe>', end="")
        cmd = input()
        com=cmd.strip()
        if com == "quit":
            break
        if com[:2] == "cd":
            os.system(com)
        if len(com) > 0:
            cmd = subprocess.Popen(com[:], shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE, stdin=subprocess.PIPE)
            output_bytes = cmd.stdout.read() + cmd.stderr.read()
            output_str = str(output_bytes, "utf-8")
            print(output_str, end="")
Pepe()

You can add in some custom commands and scripts but this is the basics of it. If you have something to add please do.

I was also looking for a way to easily change font size in terminal but that doesn't appear to be supported in any language the easiest example I found with with C/C++ on Windows and I don't have time for Windows.

Enjoy /tech/

This is a quality post. Thank you. Can you script this using image magic to keep it all in terminal?

if com[:2] == "cd":
    os.system(com)

this won't work. use os.chdir

I'll definitely have to mess around with this some more. I wasn't sure how get previous working directory so I could cd - but I think I can save each pwd a variable then move it to a second variable and write pwd to the first with each cd command. Then there was the issue of getting user's home directory. I really wasn't sure how to do it but I know when when used the subprocess method it crashed. You just gave me an idea for something too. Creating a directory history just like you have a command line history.

I need to figure out a better way to parse this and read through shit. Everything seems to work except cd.

I think I need to go over com and com2 and figure out another way to write this thing.

Thanks for pointing this out.

Thanks g. I fixed it! But fuckall that was more logic to figure out than I thought it would be and now it seems like no matter where I put the print statment for the curser and print('Pepe>', end="") it will print nothing but then once in a while it will print a ton of them. Not sure if it's end that's fucking this up of if it's my enterpreter. But cd, cd -, cd <path> work the way they are supposed to.

    while 1:
        current_dir = os.getcwd()
        cmd = sys.stdin.readline()
        com=cmd.strip()
        if com == "quit":
            break
        if com == "cd":
            old_dir=current_dir
            os.chdir("/")
            current_dir = os.getcwd()
            new_dir = current_dir
        elif com == "cd -":
            current_dir = os.getcwd()
            os.chdir(old_dir)
            old_dir = current_dir

            old_dir=current_dir
            c, d = com.split(" ")

That is really cool.

Are there any open applications available or just the library? I can't really seem to find any solid tutorials. Finding a lot of cool examples. The autism level on this is >9k
