Hi

I've finally downloaded Linux

Installed on USB

I can boot from USB

However i haven't figure out how to read the USB ...like a drive ...how to move stuff from HDD to USB , etc etc

Ie I can't get the command similar to dos. " ...  dir d:\ .. ". ( withou the dots or quotes !! )

Any  help would be appreciated

How does one start the command prompt on Linux ?

How does one get a help with all commands on Linux ?

TIA


Ps : Linux distros with GUI are super !!
