MYSQL_FIX_EXTENSIONS(1)               MySQL Database System               MYSQL_FIX_EXTENSIONS(1)



NAME
       mysql_fix_extensions - normalize table file name extensions

SYNOPSIS
       mysql_fix_extensions data_dir

DESCRIPTION
       mysql_fix_extensions converts the extensions for MyISAM (or ISAM) table files to their
       canonical forms. It looks for files with extensions matching any lettercase variant of
       .frm, .myd, .myi, .isd, and .ism and renames them to have extensions of .frm, .MYD, .MYI,
       .ISD, and .ISM, respectively. This can be useful after transferring the files from a
       system with case-insensitive file names (such as Windows) to a system with case-sensitive
       file names.

       Invoke mysql_fix_extensions like this, where data_dir is the path name to the MySQL data
       directory.

           shell> mysql_fix_extensions data_dir
