- DESCRIPTION
-
This documentation is no longer being maintained and may be inaccurate
or incomplete. The Texinfo documentation is now the authoritative
source.
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.
- -c
- N, -bytes N Print first N bytes. N is a nonzero integer, optionally
followed by one of the following characters to specify a different
unit.
- b
- 512-byte blocks.
- k
- 1-kilobyte blocks.
- m
- 1-megabyte blocks.
- -n
- N, -lines N Print first N lines.
- -q,
- -quiet, -silent Never print filename headers.
- -v,
- -verbose Always print filename headers.
- -help
- Print a usage message and exit with a status code indicating
success.
- -version
- Print version information on standard output then exit.

# include files, or, worse, just guessing them.
