Error handling for directory creation: The script uses mkdir -p to create the directory if it doesn't exist. This command will not produce an error if the directory already exists, but it will produce an error if the script does not have permission to create the directory. You might want to add error handling to handle this scenario.
Error handling for file download: The script uses curl or wget to download the file. If the download fails for any reason (e.g., network error, file not found), the script will not produce an error message. You might want to add error handling to handle this scenario.
File overwrite: If the file bike_sharing_dc.csv already exists in the directory, the script will overwrite it without warning. You might want to add a check to avoid overwriting existing files.
URL validation: The script does not validate the URL before attempting to download the file. You might want to add a check to ensure the URL is valid and correctly formatted.
Dependency on curl or wget: The script requires either curl or wget to be installed on the system. If neither of these tools is available, the script will produce an error message. You might want to consider adding additional download tools or handling this scenario differently.
