Install electronic signature on Linux

1. Extract the application data:

$tar -xvzf clicksign4linux-10.0.tar.gz

2. Install the application:

Grant execution permission on the installer script

$chmod u+x install.sh

Execute the installer

$./install.sh

You can avoid to grant permissions to the installer calling the shell and reciving the installer as argument, for example:

$bash install.sh

The electronic signature application will be installed in your HOME as a directory named clicksign that is the reason
why you do not have to execute with sudo but you will need superuser privileges because during the installation process
sudo will be called and will ask you for your UNIX password to integrate the application on the desktop.
