Just the Top (and the Bottom)
Peek at the first and last lines of a file.
head shows a file's first lines instead of the whole thing, which is exactly what you want when a file is thousands of lines long. The -3 asks for three lines; with no flag at all you get the first ten.
tail is head's twin: it shows the LAST lines of a file. Together they are how you check the beginning and end of something enormous without printing the middle.
Real terminals lean on tail constantly, because the newest lines of a log file are at the bottom.
