ZLIB_DECOMPRESS(1)	      MySQL Database System	      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  re-
	 moved	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_decom-
	 press 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).
