The command you provided is using the wrk tool to perform a benchmark test on a specified website.

Here's a breakdown of the command:

wrk: It is the command line tool used for benchmarking HTTP services.
-t${12}: This option sets the number of threads to use during the test. The value is ${12}, which implies that 12 threads will be used.
-c${400}: This option specifies the number of connections to keep open simultaneously. The value is ${400}, meaning that 400 connections will be kept open concurrently.
-d${30s}: It sets the duration of the test in seconds. The value is ${30s}, which means the test will run for 30 seconds.
"${http:--127-0-0-1:8080-index-html}": This is the URL of the website being tested. It is specified within quotes. The URL appears to be http://127.0.0.1:8080/index.html, as ${http:--127-0-0-1:8080-index-html} is likely a string placeholder that will be replaced by the actual URL.
