Remove duplicate commands from terminal history

[solazio]

When you want to execute a previous command in the terminal, if you press arrow up, it shows every previous command, if it was executed 5 times in a row. It would be useful to have an option to filter out duplicates and show that command only once, so you press arrow up twice to get to the next command and not 6 times.

Current behavior - you have to press arrow up 6 times to get to command_1:
command_1
command_2
command_2
command_2
command_2
command_2

Proposed behavior - press arrow up 2 times:
command_1
command_2
