Head (Unix)

Head (Unix)

head is a program on Unix and Unix-like systems used to display the first few lines of a text file or piped data. The command syntax is:

head

By default, head will print the first 10 lines of its input to the standard output. The number of lines printed may be changed with a command line option. The following example shows the first 20 lines of filename:

head -n 20 filename

This displays the first 5 lines of all files starting with foo:

head -n 5 foo*

Some versions omit the n and just let you say -5.

Famous quotes containing the word head:

    Heaping glowing coals on another person’s head is usually misunderstood and comes to nothing because the other person knows just as well that he is in the right and has also given some thought on his own part to heaping coals.
    Friedrich Nietzsche (1844–1900)
