## Description

**oggz-diff** is a **sh** script which  uses **oggz-dump** to generate hexadecimal packet dumps  of each input file, then outputs the difference between these dumps  using **diff**.

## Options

**oggz-diff** forwards a subset of options  accepted by **oggz-dump** and **diff**.  See  **[oggz-dump(1)](/oggz-dump/1.md)** and  **[diff(1)](/diff/1.md)** for more detail.

### oggz-dump format options

- \-b, --binary

  Generate a binary dump of each packet

- \-x, --hexadeciaml

  Generate a hexadecimal dump of each packet

### oggz-dump filtering options

- \-c **content-type**, --content-type **content-type**

  Dump only the logical bitstreams for a specific  **content-type**. Run **[oggz-known-codecs(1)](/oggz-known-codecs/1.md)** for a full list of codecs known by the installed version of oggz.

- \-s **serialno**, --serialno **serialno**

  Dump only the logical bitstream with specified  **serialno**.

- \-O, --hide-offset

  Hide the byte offset field of the preamble for  each packet dumped. This is particularly useful when comparing  Ogg bitstreams that differ only in page structure.

- \-S, --hide-serialno

  Hide the serialno field of the preamble for  each packet dumped. This is particularly useful when comparing  Ogg bitstreams that differ only in serialno assignment.

- \-G, --hide-granulepos

  Hide the granulepos field of the preamble for  each packet dumped.

- \-P, --hide-packetno

  Hide the packetno field of the preamble for  each packet dumped.

### diff options

The -w (--ignore-all-space) option to **diff** 	is always implied.

- \-q, --brief

  Output only whether files differ.

- \-C **NUM**, --context\[=**NUM**\]

  Output NUM lines of copied context.

- \-u, -U **NUM**, --unified\[=**NUM**\]

  Output NUM (default 3) lines of unified context.

- \-e, --ed

  Output an ed script.

- \--normal

  Output a normal diff.

- \--rcs

  Output an RCS format diff.

- \-y, --side-by-side

  Output in two columns.

- \-l, --paginate

  Pass the output through **pr** to  paginate it.

### Miscellaneous options

- \--verbose

  Display verbose messages.

- \-v, --version

  Display version information and exit.

- \-h, --help

  Display usage information and exit.
