NAME
head - output the first part of files
SYNOPSIS
head [-c N[bkm]] [-n N] [-qv] [--bytes=N[bkm]] [--lines=N]
[--quiet] [--silent] [--verbose] [--help] [--version]
[file...]
head [-Nbcklmqv] [file...]
DESCRIPTION
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 charac-
ters to specify a different unit.
b 512-byte blocks.
k 1-kilobyte blocks.
m 1-megabyte blocks.
-l, -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 non-zero sta-
tus.
