head - display first few lines of files
head [-count | -n count] [file ...]
The head utility copies the first count lines of each specified file to
the standard output. If no files are named, head copies
lines from the
standard input. If count is omitted, it defaults to 10.
The options are as follows:
-count | -n count
Copy the first count lines of each input file to the
output. count must be a positive decimal integer.
If more than one file is specified, head precedes the output
of each file
with the following, in order to distinguish the head of each
==> file <==
To display the first 500 lines of the file foo:
$ head -500 foo
head can be used in conjunction with tail(1) in the following way to, for
example, display only line 500 from the file foo:
$ head -500 foo | tail -1
cat(1), less(1), more(1), tail(1)
The historic command line syntax is supported by this implementation.
The head utility conforms to IEEE Std 1003.2-1992
The head utility appeared in 3.0BSD.
OpenBSD 3.6 July 14, 1993
