|HEAD(1)||General Commands Manual||HEAD(1)|
headutility copies the first count lines of each specified file to the standard output. If no files are named,
headcopies lines from the standard input. If count is omitted, it defaults to 10. The options are as follows:
headprecedes the output of each file with the following, in order to distinguish files:
==> file <==
headutility exits 0 on success, and >0 if an error occurs.
$ head -n 500 foo
headcan be used in conjunction with tail(1) in the following way to, for example, display only line 500 from the file foo:
$ head -n 500 foo | tail -1
headutility is compliant with the IEEE Std 1003.1-2008 (“POSIX.1”) specification. The historic syntax
-count is supported by this implementation.
headutility first appeared in 1BSD. Bill Joy, August 24, 1977.
