copying

sorry if this the wrong place for this but every time ive tried to copy this file i got either file does not exist or file already exist but when i try to run it, it says no such program and i did get it to copy once when i changed the name but when i ran the program it didnt work correctly so i would greatly appreciate some help sorry if this is an idiot question.

if you are trying to copy one of the programs that are on the computer you have to do

cp /rom/programs/<prog-name> <destination>

thx that worked
