EOF statement in bash script doesn't execute in an IF statement

Question

Wondering what is wrong with my syntax.

Running this bash script works as expected and all of the commands are executed:

sftp -i ~/.ssh/my_private_key $username@$host <<EOF
lcd /home/documents
get *
bye
EOF

Trying to throw the EOF inside of an IF, however, makes it not execute:

sftp -i ~/.ssh/my_private_key $username@$host

if [[ $? != 0 ]]; then
    echo "SFTP connection failed to establish."
    exit 10
else <<-EOF
    lcd /home/documents
    get *
    bye
    EOF
    echo "Files moved and connection closed."
fi

exit 0

All that happens is I see the "Connected to $host" message in terminal, and then it waits for input. If I type any commands like ls or pwd they execute, and finally typing bye closes the connection and prints "Connection closed.", but none of the commands inside EOF execute at any point.

Answer 1

The redirection should be applied to the sftp command, so the if should look something like:

if sftp -i ~/.ssh/my_private_key $username@$host  <<-EOF
lcd /home/documents
get *
bye
EOF
then
    echo "Files moved and connection closed."
else
    echo "SFTP connection failed to establish."
    exit 10
fi

After all, if the connection failed to get established, it doesn't matter if the commands are sent or not, so send them anyway.
