Little Python script to open a list of URLs from a file in browser tabs, n tabs at a time

openinbrowser.py

#! /usr/bin/python3
import webbrowser, sys

if len(sys.argv) < 3:
    print("Usage: openinbrowser.py ./urls.txt 20")
    quit()

f = open(sys.argv[1])
tabs = int(sys.argv[2])
counter = 1

for url in f:
    counter += 1
    webbrowser.open_new_tab(url)
    if counter == tabs:
        input("Press any key to continue...")
        counter = 1  

Nice, thanks.

Thank you for this! Much appreciated
