NAME

     holes — find runs of zero bytes

SYNOPSIS

     holes [-b byte] [-n minlen] [-s] [files ...]

DESCRIPTION

     holes looks for runs of zero bytes (a.k.a. holes) in the specified input files (or the
     standard input), and prints the start addresses (in hexadecimal) as well as the lengths (in
     decimal).  When multiple input files are specified, holes prefixes each line with the file
     name.

     The options are as follows:

     -b byte
             Count runs of byte, a number between 0 and 255, instead of zero bytes.

     -n minlen
             Change minimum size of holes reported.  By default, only holes of at least 64 bytes
             are reported.

     -s      Print a summary at the end how many percent of the file are runs of zeroes.

EXIT STATUS

     The holes utility exits 0 on success, and >0 if an error occurs.
