### 4.8.3 zlib\_decompress — Decompress mysqlpump ZLIB-Compressed Output

[]()

 The [**zlib\_decompress**](zlib-decompress.html) utility decompresses [**mysqlpump**](mysqlpump.html) output that was created using ZLIB compression.

Note

 If MySQL was configured with the [`-DWITH_ZLIB=system`](source-configuration-options.html#option_cmake_with_zlib) option, [**zlib\_decompress**](zlib-decompress.html) is not built. In this case, the system **openssl zlib** command can be used instead.

 Invoke [**zlib\_decompress**](zlib-decompress.html) like this:

```
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**](zlib-decompress.html) with no arguments.

 To decompress [**mysqlpump**](mysqlpump.html) LZ4-compressed output, use [**lz4\_decompress**](lz4-decompress.html). See [Section 4.8.1, “lz4\_decompress — Decompress mysqlpump LZ4-Compressed Output”](lz4-decompress.html).
