   pip install s3sql
   

Usage

1. Open a new terminal window

2. Test the CLI is properly configured with:

   s3sql --help
   

3. Set the AWS access key with:

   s3sql set-key --api-key AKIA*******
   

   This command returns the following message:

   API secret saved successfully!
   

[!TIP] Credentials are stored in the ~/s3sql directory. I.E. Windows = C:\Users\Ian\s3sql\credentials MacOS = /Users/Ian/s3sql

4. Set the AWS access secret with:

   s3sql set-secret --api-secret Gy096********
   

   This command returns the following message:

   API key saved successfully!
   

[!TIP] Credentials are stored in the ~/s3sql directory. I.E. Windows = C:\Users\Ian\s3sql\credentials MacOS = /Users/Ian/s3sql

5. List objects available. For example, to list the objects in the bucket named: osg-repo-scan-data:

   s3sql ls --bucket "s3sql-demo"
   

   This command returns a formatted table of the objects available in the bucket:
