MySQL in a Nutshell, 2nd Edition

Name

mysql_fix_extensions

Synopsis

mysql_fix_extensions path

This utility converts the file extensions of the names of MyISAM table files from uppercase to lowercase. The names of MyISAM table files typically end with .frm, .MYD, and .MYI. This utility changes the names of the last two types to .myd and .myi, respectively. This utility may be necessary when moving database files from servers running on an operating system that is case-insensitive (e.g., Windows) to one that is case-sensitive (e.g., Linux). You need to give the path to the directory for the data, that is, the directory where the database subdirectories are located.
