What does wget do?

Downloads files from the internet non-interactively via HTTP, HTTPS, or FTP.

wget [options] URL

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

How do I download a file with wget?

Use `wget https://example.com/file.txt` to download a file. It saves the file with the same name as on the server.

How do I resume a broken download?

Use `wget -c URL` to resume a partially downloaded file. The `-c` flag continues where the previous download left off.

How do I save a file with a different name?

Use `wget -O newname.txt URL` to save the downloaded file with a custom name instead of the server's filename.

How do I download in the background?

Use `wget -b URL` to run the download in the background. Progress is logged to wget-log. Use `tail -f wget-log` to monitor.

How do I limit download speed?

Use `wget --limit-rate=200k URL` to limit download speed to 200KB/s. This prevents bandwidth saturation.

How do I download an entire website?

Use `wget -r -np URL` to recursively download a site. `-np` prevents ascending to parent directories. Add `--wait` to avoid overwhelming the server.

How do I download with authentication?

Use `wget --user=username --password=password URL` or `wget --user=username URL` to be prompted for the password.

How do I ignore SSL certificate errors?

Use `wget --no-check-certificate URL` to skip SSL verification. Only use this for testing, as it compromises security.
