У меня со вторым проблема, написано
1. Unpack the IntelliJ IDEA distribution archive that you downloaded
where you wish to install the program. We will refer to this
location as your {installation home}.
2. To start the application, open a console, cd into "{installation home}/bin" and type:
./idea.sh , если я распаковала в загрузки, то как выполнить это действие : cd into "{installation home}/bin?
