How to create a signed URL for accessing an S3 object using s3cmd?

To create a signed URL for accessing an S3 object using s3cmd, you can follow these steps:

1. Install s3cmd on your local computer if you haven't already.

2. Configure s3cmd by running the following command and providing your AWS access key and secret key:

   s3cmd --configure

3. Generate a signed URL using the following command:

   s3cmd signurl s3://<bucket-name>/<object-key> <expiry-time-in-seconds>

   Replace <bucket-name> with the name of your S3 bucket and <object-key> with the key of the object you want to access. Set <expiry-time-in-seconds> to the desired expiration time for the signed URL.

4. The command will generate a signed URL that you can use to access the S3 object. You can copy the URL and use it in your application or share it with others.

Note: The signed URL will only provide temporary access to the S3 object and will expire after the specified time.
