# Exit on errors
set -e
set -o pipefail
# Filename of captured image
FILE="$(date +%Y-%m-%d-%H-%M-%S).png"
# User/host 
HOST="user@xx.xxx.xxx.xxx"
# Capture screen (interactively) and save image to the desktop
screencapture -i ~/Desktop/$FILE
# Upload the captured image to the server
scp -qC ~/Desktop/$FILE $HOST:/home/ipfs/
# SSH into server and, as user ipfs, add image to IPFS
# Store the returned CID into the variable $CID
CID=$(ssh $HOST "su ipfs -c 'ipfs add -Q /home/ipfs/$FILE'")
# Clean up
ssh $HOST "rm /home/ipfs/$FILE"
# Put gateway URL of the added image on the clipboard
