HEAD(1) General Commands Manual HEAD(1) NAME head -- display first lines of a file SYNOPSIS head [-qv] [-n count | -c bytes] [file ...] DESCRIPTION This filter displays the first count lines or bytes of each of the speci- fied files, or of the standard input if no files are specified. If count is omitted it defaults to 10. The following options are available: -c bytes, --bytes=bytes Print bytes of each of the specified files. -n count, --lines=count Print count lines of each of the specified files. Both count and bytes may also be specified with size suffixes sup- ported by expand_number(3). -q, --quiet, --silent Suppresses printing of headers when multiple files are being exam- ined. -v, --verbose Prepend each file with a header. If more than a single file is specified, or if the -v option is used, each file is preceded by a header consisting of the string "==> XXX <==" where "XXX" is the name of the file. The -q flag disables the printing of the header in all cases. EXIT STATUS The head utility exits 0 on success, and >0 if an error occurs.
