SYNOPSIS

head [ OPTION ]...[ FILE ]...

DESCRIPTION

Print the first 10 lines of each FILE to standard output. With more than one FILE, precede each with a header giving the file name.

With no FILE, or when FILE is -, read standard input.

Mandatory arguments to long options are mandatory for short options too.

-c , --bytes = [ -]NUM print the first NUM bytes of each file; with the leading ' -', print all but the last NUM bytes of each file

-n , --lines = [ -]NUM print the first NUM lines instead of the first 10; with the leading ' -', print all but the last NUM lines of each file

-q , --quiet , --silent never print headers giving file names

-v , --verbose always print headers giving file names

-z , --zero -terminated line delimiter is NUL, not newline

--help display this help and exit

--version output version information and exit

NUM may have a multiplier suffix: b 512, kB 1000, K 1024, MB 1000*1000, M 1024*1024, GB 1000*1000*1000, G 1024*1024*1024, and so on for T, P, E, Z, Y. Binary prefixes can be used, too: KiB=K, MiB=M, and so on.
