lekkerlinux mostly you'll just need to know:
sudo eopkg up
eopkg search searchterm
sudo eopkg it packagename
sudo eopkg rm packagename
for things it's pretty much just Linux as usual I think, except instead of sudo update-grub
it's sudo clr-boot-manager update
(if you're a GRUB user...)
if you're wondering what commands are available, apropos
is a very handy command- for example if I forgot what my screenshot utility was called:
max@max ~> apropos screenshot
gnome-screenshot (1) - capture the screen, a window, or an user-defined area and save the snapsh...
idevicescreenshot (1) - Gets a screenshot from the connected device.
