<img src='content_image/767486.jpg'>

Read given file after global files are read. 

• --defaults-file 

<img src='content_image/767485.jpg'>

Read default options from given file only. 

• --defaults-group-suffix 

<img src='content_image/767484.jpg'>

Also read groups with concat(group, suffix). 

• --encrypt-backup 

<img src='content_image/767483.jpg'>

When used, this option causes all backups to be encrypted. To make this happen whenever ndb_mgm  is run, put the option in the [ndb_mgm]  section of the my.cnf  file. 

• --execute=command , -e command 

<img src='content_image/767482.jpg'>

This option can be used to send a command to the NDB Cluster management client from the system shell. For example, either of the following is equivalent to executing SHOW  in the management client: 

shell> ndb_mgm -e "SHOW" shell> ndb_mgm --execute="SHOW" 

This is analogous to how the --execute  or -e  option works with the mysql  command-line client. See Section 4.2.2.1, “Using Options on the Command Line” .

## Note 

If the management client command to be passed using this option contains any space characters, then the command must  be enclosed in quotation marks.
