You can use Wildcards in the AWS CLI commands as the special characters which enable you to create specific patterns in the commands. For example, the cp command is used to copy files from the clouds to the directory and vice-versa. 

 In this article, we have explained how you can use wildcards to a group of files i.e., cp with AWS CLI.  So without further delay, let’s get into the topic. 

How can you use the Wildcards to ‘cp’ a File Group with AWS CLI?

The following steps will help you understand the process.

Step 1: 

Start a local system and open a ‘Terminal.’

Step 2:

Cross-check whether you have installed AWS CLI on your system by using the below command:

After running the above command, it will display ‘aws-cli/2.11.0’ which is a AWS CLI installed version.

Step 5:

Now, use the below command for AWS CLI for uploading files on the S3 bucket

The aforementioned command from the local directory copies all the files and uploads them to the S3 bucket. The wildcard used here will not copy the myapp.html file:

Step 6:

Navigate to the S3 dashboard and press on the ‘Buckets’ page

Press on the bucket list and open the list:

Go to the ‘prefix/’ folder:

You can see that all the files are copied to the S3 bucket excluding myapp.html which is not included in the wildcard:

Navigate back to the buckets page and press on the Empty button:

Write ‘permanently delete’ and then press on the ‘Empty’ button.

Now, click on the ‘Exit’ button. 

Step 7:

The below command will help you to use the wildcards that are included:

By appending a "*" to the command above, everything was omitted, and only the "myapp.html" file was included:

Only the "myapp.html" file is present in the bucket; other files have been left out.
