head

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.

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, R, Q. Binary prefixes can be used, too: KiB=K, MiB=M, and so on.
