Search commands in Ubuntu 18.04 applications

Question

I used Ubuntu 16.04 with Unity. In every application I used on the system, when I needed to use a command I didn’t know where to find, I would press the alt key and open a search bar so I could search which command I wanted. I installed Ubuntu 18.04, which uses gnome and realized that this function no longer exists with alt key (which just opens the menu 'file', 'edit' etc). Is there another way I can perform this research?

Answer 1

Using command

ls ${PATH//:/ }

This will list all commands in your $PATH environment variable.

To store the result in a file, you can redirect the output to a file.

ls ${PATH//:/ } > meusComandos.txt
