4.8.3 zlib_decompress — Decompress mysqlpump ZLIB-Compressed Output解压mysqlpump ZLIB压缩输出

The zlib_decompress utility decompresses mysqlpump output that was created using ZLIB compression.zlib_decompress实用程序解压缩使用zlib压缩创建的mysqlpump输出。

Note注意

If MySQL was configured with the -DWITH_ZLIB=system option, zlib_decompress is not built. 如果MySQL配置了-DWITH_ZLIB=system选项，则不会构建zlib_decompress。In this case, the system openssl zlib command can be used instead.在这种情况下，可以使用系统openssl -zlib命令。

Invoke zlib_decompress like this:按如下方式调用zlib_decompress：

zlib_decompress input_file output_file

Example:

mysqlpump --compress-output=ZLIB > dump.zlib
zlib_decompress dump.zlib dump.txt

To see a help message, invoke zlib_decompress with no arguments.要查看帮助消息，请不带参数地调用zlib_decompress。

To decompress mysqlpump LZ4-compressed output, use lz4_decompress. 要解压缩mysqlpump LZ4压缩输出，请使用lz4_decompress。See Section 4.8.1, “lz4_decompress — Decompress mysqlpump LZ4-Compressed Output”.请参阅第4.8.1节，“lz4_decompress——解压缩mysqlpump lz4压缩输出”。
