NetSpeedTest

NetSpeedTest is a small shell script for quick command-line network speed checks.

It provides:

• Download speed test (default)
• Upload speed test
• HTTP status and elapsed time output

Requirements

• Linux (the script reads /proc/uptime)
• curl
• awk
• dd

Usage

Run the default download test:

./netspeedtest.sh

Run the upload test:

./netspeedtest.sh -u

Show help:

./netspeedtest.sh -h

Quick download (curl)

Default download test

Download:

curl -fksSL https://raw.githubusercontent.com/pepa-cz/netspeedtest/main/netspeedtest.sh -o netspeedtest.sh
chmod +x netspeedtest.sh

Run:

./netspeedtest.sh

Upload test

Download:

curl -fksSL https://raw.githubusercontent.com/pepa-cz/netspeedtest/main/netspeedtest.sh -o netspeedtest.sh
chmod +x netspeedtest.sh

Run:

./netspeedtest.sh -u

How it works

• Download test requests a 100MB file and calculates Mbps.
• Upload test sends 64MB of generated data and calculates Mbps.
• Output includes HTTP status, elapsed time, and measured speed.

Notes

• Upload data is sent to a public endpoint: https://x0.at/.
• Results are quick estimates and may vary with routing, server load, and network conditions.
