I'm trying to write a Bash script that will SSH into a machine and create a directory. The long-term goal is a bit more complicated, but for now I'm starting simple. However, as simple as it is, I can't quite seem to get it. Here's my code:
#!/bin/bash
ssh -T tunneluser@111.222.333.444 <<EOI
# Fix "TERM environment variable undefined" error.
TERM=dumb
export TERM
# Store todays date.
NOW=$(date +"%F")
echo $NOW
# Store backup path.
BACKUP="/backup/$NOW"
[ ! -d $BACKUP ] && mkdir -p ${BACKUP}
echo $BACKUP
exit
EOI
It runs without any explicit errors. However, the echoed $NOW and $BACKUP variables appear empty, and the /backup directory is not created. How do I fix this?
