I've used this for awhile now as a quick way to control some things on my raspberry pis running in my home from my phone.

Sometimes you just want something quick and a little bash script is perfect. For example, I use getmail to periodically fetch my email from all of my email providers, gmail, hotmail, etc.. Whenever I needed to get email quicker (like if I was sent a security code or something) I had to SSH into the server and manually call getmail to fetch it before the scheduled time. With pushback I have a little simple script that gives me the ability to do it from the pushback app and it is a real time saver.

Here is my script I used in case anyone is interested:

  #!/bin/bash
  while true; do
        result="$(curl https://api.pushback.io/v1/send_sync \
                -u <my_token>: \
                -d 'id=Channel_379' \
                -d 'title=Check Email?' \
                -d 'body=Choose from the actions' \
                -d 'action1=gmail' \
                -d 'action2=hotmail' \
                -d 'action3=personal')"
        if [[ "$result" == "gmail" ]]; then 
                getmail -r gmail
        elif [[ "$result" == "hotmail" ]]; then 
                getmail -r hotmail
        elif [[ "$result" == "personal" ]]; then 
                getmail -r personal
        fi 
        sleep 15
  done

I've used it to also notify me when long running commands finish, as a way to add manual review to an otherwise automated process, etc.
