Description

Prints the contents of a file to standard output in a variety of formats. (If no filename is specified, it acts on the contents of standard input.) The name is an acronym for octal dump , from its default behavior of displaying files as series of octal numbers .

od has been deprecated in favor of hexdump ; in fact, the two binaries are hard-linked to the same data. However, traditional od syntax applies when invoked by that name. See the hexdump manpage for more.
