This manual page documents the GNU version of head. head prints the first part (10 lines by default) of each given file; it reads from standard input if no files are given or when a filename of `-' is encountered. If more than one file is given, it prints a header consisting of the file's name enclosed in `==>' and `<==' before the output for each file. OPTIONS head accepts two option formats: the new one, in which numbers are arguments to the option letters, and the old one, in which the number precedes any option letters. -c N, --bytes N Print first N bytes. N is a nonzero integer, optionally followed by one of the following charac- ters to specify a different unit. b 512-byte blocks. k 1-kilobyte blocks. m 1-megabyte blocks. -n N, --lines N Print first N lines. -q, --quiet, --silent Never print filename headers. -v, --verbose Always print filename headers. --help Print a usage message and exit with a status code indicating success. --version Print version information on standard output then exit.
