NAME
head - output the first part of files
SYNOPSIS
head
[-c N[bkm]] [-n N] [-qv] [--bytes=N[bkm]] [--lines=N]
[--quiet] [--silent] [--verbose] [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 characters 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.
The long-named options can be introduced with `+' as well as `--',
for compatibility with previous releases. Eventually support for `+'
will be removed, because it is incompatible with the POSIX.2 standard.
