trying to copy the file to roms folder, and im not bright enough for it to work. my command is:

cp retroarch.cfg home/pi/retropie/roms

i have tried other variations of this using the ~ for ‘home’ and i always get an error that the directory or file doesn’t exist. If i use only ‘roms’ for my destination i do not get an error, but nothing is copied. I also added ‘sudo’ in front thinking that might help, but no luck. What am i doing wrong?
