Run another bash script after successful execution of external bash

[theomolenaar]

I have two bash scripts: backup-plex.sh and update-plex.sh
update-plex.sh looks like this:

Code:

#!/bin/bash
JAIL_NAME=plex
#MAKE BACKUP of plex jail before updating
#https://stackoverflow.com/questions/38978650/run-a-script-in-the-same-directory-as-the-current-script
__dir="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
source ${__dir}/backup-plex.sh

if [$? -eq 0]; then
    echo "Backup $JAIL_NAME succeeded" >> /mnt/pool1/media/logs/mediajail.log

    #After backup is finished, update plex
    echo "---Starting updating jail: ${JAIL_NAME} ---" $(date) >> /mnt/pool1/media/logs/mediajail.log
    #https://github.com/mstinaff/PMS_Updater.git
    iocage exec $JAIL_NAME 'sh /usr/local/PMS_Updater/PMS_Updater.sh -v -a'
    if [$? -eq 0]; then
    echo "Update Completed" $(date) >> /mnt/pool1/media/logs/mediajail.log
    #email notification
    Plex updated to latest version | /usr/bin/mail -s "Software Update Completed" jowandijkhuis@gmail.com
    else
        echo "Update $JAIL_NAME failed" >> /mnt/pool1/media/logs/mediajail.log
    fi

else
    echo "Backup $JAIL_NAME failed" >> /mnt/pool1/media/logs/mediajail.log
fi

The first if statement checks if the backup completes without errors. If no errors then the update script should start. Unfortunately my code doesn't start the update part inside the if. The backing up part works as it should. I'm guessing something is wrong with $? -eq 0. Any ideas on how to fix this?
