Which Linux command prints the beginning of a file?

Which Linux command prints the beginning of a file?

• A. Tail
• B. Head
• C. Cat
• D. More

Answer: (B)

You're being asked which command shows the start of a file. The command that does this is head. It outputs the first part of a file, by default the first ten lines, which makes it perfect for quickly checking the top of a file like a script, config, or log. You can adjust how many lines to display with -n, for example head -n 20 filename to see the first 20 lines (or head -20 filename in some shells). By contrast, tail shows the end of a file, cat prints the entire file, and more provides a paging view to navigate through long files.
