📝 Syntax

Which wget command downloads a file and saves it with a custom name?

You want to download https://example.com/data.csv but save it as mydata.csv locally. Which command does this correctly?

A wget https://example.com/data.csv -O mydata.csv

B wget -o mydata.csv https://example.com/data.csv

C wget --save-as mydata.csv https://example.com/data.csv

D wget --output-file=mydata.csv https://example.com/data.csv

💡 Hint

The -O option sets the output file name.

The -O option followed by a file name tells wget to save the download with that name. The other options are incorrect or mean something else.

What happens if you run wget with the -c option on a partially downloaded file?

What will wget do?

Linux CLI

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

A Restart the download from the beginning, overwriting the file.

B Download the file but save it with a different name to avoid overwriting.

C Resume the download from where it stopped, appending to the existing file.

How to download multiple files listed in a text file using wget?

You have a file urls.txt with a list of URLs, one per line. Which wget command downloads all files listed in urls.txt?

A wget -i urls.txt

B wget -f urls.txt

C wget --list urls.txt

D wget --input-file=urls.txt

💡 Hint

The -i option tells wget to read URLs from a file.

The -i option followed by a file name tells wget to read URLs from that file and download each one. The other options are invalid or do different things.
