- 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, --_b_y_t_e_s _N
- Print first N bytes. N is a nonzero integer, option-
- ally 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, --_l_i_n_e_s _N
- Print first N lines.
-
- -_q, --_q_u_i_e_t, --_s_i_l_e_n_t
- Never print filename headers.
-
- -_v, --_v_e_r_b_o_s_e
- 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.
