Shell Script: execute & repeat a python program that needs extra input

Question

I have to run this python command: python manage.py rebuild_index at a certain time and rerun again. Therefore, I am trying the shell script to run it. However, when run this python command, I have to choose y to continue.

my run_rebuild.sh :

#!/bin/sh
python manage.py rebuild_index

Moreover, how can I let the run_rebuild.sh rerun again after every 60 seconds?

Answer 1

尝试使用管道 （将输出从echo重定向到python的stdin ）：

echo "y" | python manage.py rebuild_index

Answer 2

You can use yes for this:

yes | python /manage.py rebuild_index

One way to run your script every minute:

while yes | python /manage.py rebuild_index; do
  sleep 60
done

The above will run your script every 60 second until it fails.

Answer 3

You can use echo "y" (as @LogicStuff said) and cron jobs to accomplish this.

Create a script file (let's say your_script.sh ) and add your command to it

echo "y" | python manage.py rebuild_index

To use cron you can use the following steps:-

crontab -e

This will open up the cronjob file in your default editor, add the following line to the file

* * * * * sh /path/to/your_script.sh
