This error occurs because the du command on Red Hat Enterprise Linux 5.7 does not comply with the POSIX standard. For more information, see AutoMySQLBackup 3.0 warning on du in Centos (5.7)

The POSIX specifications are. it seems, that the Centos 5.7 version of du is not POSIX compliant, but will soon be. I have done my best to use only POSIX compliant syntax to assure the bug-free running on most systems. unfortunately, I can't take care of every system and distribution, which chooses to defy POSIX syntax. for other people and myself, it wocould be a good idea to get the options of du on Centos 5.7, so please post 'Du -- help '.

In the command du -- help, you can see the following information from the help information:

You can find the following script by modifying the script/usr/local/bin/automysqlbackup, modify the "echo 'Du-hsH" $ {CONFIG_backup_dir} "'to echo 'Du-hs" $ {CONFIG_backup_dir} "' to solve the problem.

This problem does not occur in Red Hat Enterprise Linux Server release 6.6. its du version is 8.4, and the du command version on Red Hat Enterprise Linux 5.7 is du (GNU coreutils) 5.97.

# Du -- version

Du (GNU coreutils) 8.4
