#! /usr/bin/env sh

# Creates a customly named shortcut on the desktop for the normal user, which
# opens the URL given as an argument in the default browser.
#
# After the script has run log out or restart the computer for the changes to
# take effect.
#
# Arguments:
# 1: A boolean to decide whether to add or not. A checked box will
# add the shortcut and an unchecked will remove it
# 2: The URL to visit when clicked
# 3: The name the shortcut should have - it needs to be a valid filename!
# 4: The path to an icon. If empty an icon from the current theme is used, specified below

Beskrivelse

Opretter eller sletter en genvej til til en valgfri hjemmeside på skrivebordet, med det angivne navn. Efter kørsel tager det effekt efter logud.

Dette script er blevet testet og virker på Ubuntu 22.04.

Parametre

Aktiver?: Sæt hak for at oprette genvejen, Lad stå tom for at slette den, så fremt den findes.
URL til webstedet. Ingen mellemrum. Husk https:// eller http:// foran - det skal være den fulde adresse (kopier den eventuelt fra adresselinien i browseren), fremfor eks. bare eboks.dk eller www.eboks.dk, som ikke vil virke.
Genvejsnavn: Navnet genvejen skal have på skrivebordet. Bemærk at navnet ikke må indeholde mellemrum.
Ikon. Du kan selv uploade et ikon-billede, eller du kan undlade og så bruger den et standardikon. Upload en kvadratisk .SVG- eller .PNG-fil.
