Productivity System Step 5: Read Without Opening

On your own machine, find a log file or any long text file. Answer four questions about it using only the terminal: how many lines it has, what its first five lines are, what its last five lines are, and what lines 10 through 15 say. Write down the command for each. Then open a file with less, scroll with Space, search with a slash followed by a word, and leave with q. Being able to answer a question about a file without opening an editor is a habit that compounds, because it works over SSH on a server where there is no editor to open.
