This code is a shell script that performs the following tasks:

1. The set -e command ensures that the script exits immediately if any command within it fails (returns a non-zero status).

2. The script checks if the file specified by the $SCHEDULE_FILE variable does not exist using the condition [ ! -f "$SCHEDULE_FILE" ].

   • If the schedule file does not exist:

     • It prints the message: "Downloading schedule.json from latest release...".
     • It uses the gh release download command from the GitHub CLI (gh) to download a file named schedule.json from the latest release of the specified GitHub repository (savente93/SPEC0-schedule). The --pattern schedule.json option ensures that only the schedule.json file is downloaded. The -O "$SCHEDULE_FILE" option specifies the location where the file should be saved as defined by the $SCHEDULE_FILE variable.

   • If the schedule file does exist:

     • It prints the message: "Schedule file already exists at $SCHEDULE_FILE".

Summary

This script ensures that a schedule.json file is available locally. If it is not already present, it downloads the file from the latest GitHub release of the savente93/SPEC0-schedule repository and saves it to the location defined by the $SCHEDULE_FILE variable. If the file already exists, it notifies the user with a message.
