8. Summary of ebzip Options

The ebzip command supports both traditional single-letter options and mnemonic long option names. Long option names are indicated with `--' instead of `-'. Abbreviations for option names are allowed as long as they are unique.

-f

--force-overwrite

Overwrite existed files without confirmation. This option is ignored when the action is information, or when you specify the `--test' (`-t') option.

(See section 4.6 Overwrite Old Files, for more details).

-h

--help

Output help message to standard out, then exit.

-i

--information

Output compression status of the specified CD-ROM book.

(See section 6. Information, for more details).

-k

--keep

Don't delete an input file when the corresponding output file has been written. This option is ignored when the action is information, or when you specify the `--test' (`-t') option.

(See section 4.2 Example of Compression (2), for more details).

-l integer

--level integer

Specify compression level. integer must be `0', `1', `2', `3', `4' or `5'. The level 0 is fastest but least compression method. The level 5 is slowest but best compression method. The defalt level is 0. This option is ignored when the action is uncompression or information.

(See section 4.3 Compression Level, for more details).

-n

--no-overwrite

Skip existed files without confirmation for overwriting. This option is ignored when the action is information, or when you specify the `--test' (`-t') option.

(See section 4.6 Overwrite Old Files, for more details).

-o directory

--output-directory directory

Specify a directory of output files. The default is the current directory (`.'). This option is ignored when the action is information, or when you specify the `--test' (`-t') option.

-q

--quiet

--silence

Supress all information and warning messages. However, when an output file has already exists, during compression/uncompresion, ebzip still asks you whether the output file may be overwritten or not. To supress this question, specify the `--force-overwrite' (`-f') or `--no-overwrite' (`-n') option. This option is ignored when the action is uncompression or information.

-s types

--skip-content types

Specify data types of files to be ignored. types must be a list of data type names separated by a comma (`,'). The data type names ebzip currently recognizes are: font, graphic, sound and movie. By default, none is skipped.

-S subbooks

--subbook subbooks

Specify target subbooks to compress, uncompress or output information. subbooks must be a list of directory names of subbooks separeted by a comma (`,'). By default, all subbooks are specified as target.

(See section 4.5 Partial Compression, for more details).

-t

--test

Don't write compression/uncompression data to the actual files. This option is ignored when the action is information.

(See section 4.4 Test, for more details).

-u

--uncompress

Uncompress a CD-ROM book.

(see section 5. Uncompression, for more details).

-v

--version

Output version number to standard out, then exit.

-z
