Sounds like your trying to do things the hard way, To transfer between systems
or backup stuff I use rsync. You were using scp which uses ssh as well.

#!/bin/bash
rsync -aPrvz "$1" pi@10.0.0.5:/mystic

as a bash script to copy argument $1 file to /mystic user pi at 10.0.0.5
If you look it up there are ways to handle passwords like RSYNC_PASSWORD 
variable or --password-file and such.
