using scp

install open-ssh first.

then if the host ip address is 1.1.1.130 and want to copy file called copy.txt to host's /home directory.

then scp copy.txt user@1.1.1.130:/home
the other way is scp user@1.1.1.130:/home/copy.txt or to give directory path

this can be used in iphone as well(never used android phone so i don't know)
