# A simple script for sending data to another computer's clipboard via SSH. Acts
# as a universal clipboard. This script must be available on the remote. Pipe
# through gpg if you want the contents encrypted.
#
# It helps if your ssh connection is pubkey authenticated and password-less.
#
# Requires: pb (script, in same folder)
#
# Workflow:
#   host  $ echo "Hello world!" | rclip guest
#   guest $ rclip
#         Hello world!
#     OR
#   host  $ echo "Hello world!" | gpg -e | rclip.sh guest
#   guest $ rclip | gpg -d
#         Hello world!
