Using the wget Command in the ChromeOS Linux Environment

The wget command is a powerful tool for downloading files from the internet via the command line. It supports HTTP, HTTPS, and FTP protocols and is useful for automating downloads in the ChromeOS Linux (Crostini) environment.

Installing wget (If Not Preinstalled)

Most ChromeOS Linux environments include wget by default. However, if it is missing, you can install it using:

sudo apt update && sudo apt install wget

Basic Usage

Downloading a File

To download a file from a URL, use:

wget https://example.com/file.zip

Downloading to a Specific Directory

To specify a directory for the downloaded file:

wget -P /path/to/destination https://example.com/file.zip

Resuming a Download

If a download was interrupted, you can resume it with:

wget -c https://example.com/file.zip

Downloading Multiple Files

Create a text file (urls.txt) containing URLs, one per line, and download them all:

wget -i urls.txt

Downloading a Website Recursively

To download an entire website for offline browsing:

wget -r https://example.com/

Limiting Download Speed

To limit the download speed to prevent bandwidth overuse:

wget --limit-rate=100k https://example.com/file.zip

Downloading with a Specific User Agent

Some websites block unknown user agents. You can specify a browser user agent:

wget --user-agent="Mozilla/5.0" https://example.com/file.zip

Authentication with Username and Password

To download from a password-protected site:

wget --user=username --password=password https://example.com/protected.zip

Skipping SSL Certificate Verification

If encountering SSL errors, you can bypass verification (not recommended for security reasons):

wget --no-check-certificate https://example.com/file.zip

Practical Use Cases

  • Downloading files directly to ChromeOS Linux: 
    wget https://example.com/software.deb
  • Automating multiple downloads with a list of URLs: 
    wget -i urls.txt
  • Mirroring an entire website for offline access: 
    wget -r https://example.com/

Conclusion

The wget command is an essential tool for downloading files efficiently in the ChromeOS Linux environment. With its powerful features, it is invaluable for both simple file retrieval and complex download automation.
