The db command is unique to sme server. It is used to add settings to the various configuration databases which are then incorporated into the standard configuration files in /etc/.... via the template expansion process.
The '''db''' command is unique to SME Server, and is the command line user interface to the '''db system'''. It is used to manipulate configuration setting of the various configuration databases which are then incorporated into the standard configuration files in /etc/.... via the template expansion process.
To display the syntax, at a command prompt type
The '''db system''' comes with default values that can be manipulated by either manually through the CLI or fully automatic through the Server Manager. This tutorial explains manipulating the '''db system''' manually through the CLI.
db
To display the syntax issue the following command:
/sbin/e-smith/db
which will result in the db help output below, for we did not pass any parameters.
/sbin/e-smith/db dbfile keys
/sbin/e-smith/db dbfile keys
/sbin/e-smith/db dbfile print [key]
/sbin/e-smith/db dbfile print [key]

Apply the above "reasoning" to any database and the the syntax presented by issuing db then makes sense.

====Check if a key is used====
To check if a key is used, grep templates
Eg :
grep -irn grapCutof /etc/e-smith/templates
grep -rn AutoBlock /etc/e-smith/templates
{{Note box|: via CLI so it is easy to make mistakes.
Hence it is safer to user server manager when there is an entry to configure key.}}
{{Warning box|Database parameters are case sensitive so take great care when typing at the server shell because no error messages are given should you make a mistake.}}
