7.4.5 Exercises

1. Write a bash script that takes a file path as an argument and copies that file to a designated folder on your server.

    $ scp path/to/file username@IP_address:path/to/folder/on/server/
   

2. Find a file online that changes periodically, then write a program to download that file every time it changes.

   • Method 1: Manually using console

      $ curl -O The_link_to_the_file
     

   • Method 2: Automating this task using cron table

      crontab -e
     

     Edit the cron table file and adjust your preferred period: ```bash # Edit this file to introduce tasks to be run by cron. # # m h dom mon dow command

   # Runs every hour at the start of the hour 00 * * * * curl -O The_link_to_the_file ```

   Haven’t created my own yet, but you can make your own and contribute to this project.

   To contribute, remove my quotes in this question and replace them with a link to your BOT repo.
