The head command is used on Linux systems at the terminal. This information was obtained from a Kali Linux distribution using man head.
head – output the first part of files
head [OPTION]... [FILE]...
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.

|-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|
