ZLIB_DECOMPRESS(1)

NAME
zlib_decompress - decompress mysqlpump ZLIB-compressed output

SYNOPSIS

zlib_decompress input_file output_file

DESCRIPTION

The zlib_decompress utility decompresses mysqlpump output that was created using ZLIB compression.

    Note

    zlib_decompress is deprecated as of MySQL 8.0.34; expect it to be removed in a future version of MySQL. This is because the associated mysqlpump utility is deprecated as of MySQL 8.0.34.

    Note

    If MySQL was configured with the -DWITH_ZLIB=system option, zlib_decompress is not built. In this case, the system openssl zlib command can be used instead.

Invoke zlib_decompress 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 with no arguments.

To decompress mysqlpump LZ4-compressed output, use lz4_decompress. See lz4_decompress(1).
