Download Files and Check MD5 Hash with aria2c on Ubuntu

This article provides a concise tutorial on using the aria2c tool within the Ubuntu operating system to download files and subsequently calculate their MD5 hash for verification. It covers installation, execution of download commands, and the specific utilities required to generate and compare checksums to ensure file integrity.

Install aria2

Open your terminal and install aria2 if it is not already present on your system. Run the following command to update your package list and install the utility: sudo apt update && sudo apt install aria2

Download the File

Use aria2c to download your target file by specifying the direct URL. Replace the example link with your actual file source: aria2c https://example.com/file.zip

Calculate the MD5 Hash

Once the download completes, use the md5sum utility included in Ubuntu to generate the hash of the downloaded file. Replace file.zip with your actual filename: md5sum file.zip

Verify the Checksum

Compare the output string from the md5sum command with the MD5 hash provided by the file source. If the two strings match exactly, the file is intact and safe to use. If they differ, the download may be corrupted and should be retried.
