This manual page documents the GNU version of head. head prints the first part (10 lines by default) of each given file; it reads from standard input if no files are given or when a filename of ’-’ is encountered. If more than one file is given, it prints a header consisting of the file’s name enclosed in ’==>’ and ’<==’ before the output for each file.
OPTIONS
head accepts two option formats: the new one, in which
numbers are arguments to the option letters, and the old
one, in which the number precedes any option letters.
