Below is an example of a Bash script that takes a URL as input and uses the wrk2 tool to run benchmarking against that URL. Please make sure you have wrk2 installed on your system before using this script.

benchmark.sh

#!/bin/bash

# Check if wrk2 is installed
if ! command -v wrk2 &> /dev/null; then
    echo "wrk2 is not installed. Please install it: https://github.com/giltene/wrk2"
    exit 1
fi

# Check if an argument (URL) is provided
if [ -z "$1" ]; then
    echo "Usage: $0 <url>"
    exit 1
fi

# URL to test
URL="$1"

# Other wrk2 options you can customize
THREADS=4
CONNECTIONS=100
DURATION=30s

# Run wrk2 benchmark
wrk2 -t${THREADS} -c${CONNECTIONS} -d${DURATION} ${URL}
