MirOS Manual: head(1)

HEAD(1)                      BSD Reference Manual                      HEAD(1)

NAME

     head - display first few lines of files

SYNOPSIS

     head [-count | -n count] [file ...]

DESCRIPTION

     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 standard
             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:

           ==> file <==

EXIT STATUS

     The head utility exits 0 on success, and >0 if an error occurs.

EXAMPLES

     To display the first 500 lines of the file foo:

           $ head -n 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 -n 500 foo | tail -1

SEE ALSO

     cat(1), less(1), more(1), tail(1)

STANDARDS

     The head utility is compliant with the IEEE Std 1003.1-2008 ("POSIX")
     specification.

     The historic syntax -count is supported by this implementation.

HISTORY

     The head utility first appeared in 1BSD.
