To clone a repository via Git, you need to open a terminal. However, if you prefer GUI (Graphical user interface) to CLI (Command line interface), then this script, which uses GTK4 libraries and libadwaita, may be useful. This script allows you to download a Git repository without using a terminal. Just type paste URL on Git repository (e.g. https://github.com/example/app, or https://gitlab.com/example/app) and click on button "Clone".
Install this script using this simple command (in Linux terminal):
wget -qO /tmp/install.sh https://raw.githubusercontent.com/vikdevelop/gitcloner-gui/main/install.sh && sh /tmp/install.sh
