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) and diff(1) 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) 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.
