Add the following lines to your .bashrc on the remote machine.
export DESKTOP=$(last -100 |grep $(whoami) |head -n 1 |perl -ane 'print $F')
if [ -z "$1" ]; then
echo "put - Sends specified files to Desktop of local machine";
echo "usage: put filesToSend";
find "$*" |xargs -I % scp % $DESKTOP:~/Desktop
Then reload the file with source .bashrc. You should now be able to type put fileName, and the file will appear on your desktop. As long as you have your rsa keys set up, otherwise it will ask for a password too. It works for multiple files too, such as *.png.
I find it useful for quickly viewing pdfs and images.
