SQLcl - The alias command

Was kann man in SQLcl mit Aliassen machen? 

Alias is a command which allows you to save a sql, plsql or sqlplus script and assign it a shortcut command. The alias command is persistent. This means when you start a new SQLcl session, it will load all your previously declared aliases.
