NAME¶

kdb-check - Perform internal checks

SYNOPSIS¶

kdb check [<plugin>]

DESCRIPTION¶

This command is used to perform checks on the key database or an Elektra plugin.

Where the option argument, plugin is the plugin that a user wants to check. Use -c to pass options to that plugin. If no plugin argument is provided a check will be performed on the key database itself. Special values are returned upon exit to represent the outcome of a check.

OPTIONS¶

-H, --help

Show the man page.

-V, --version

Print version info.

-p, --profile <profile>

Use a different kdb profile.

-C, --color <when>

Print never/auto(default)/always colored output.

-f, --force

The user can also use this tool to perform write tests. Please note that this can result in configuration files being changed!

-v, --verbose

Explain what is happening.

-c, --plugins-config <plugins-config>

Add a plugin configuration in addition to /module.

RETURN VALUES¶

There are two different types of checks, a check on a plugin (by specifying the name of a plugin as an argument) or a check on the key database itself.

The outcome of a check on the key database is returned as an exit status. This integer represents an 8-bit pattern. Each bit represents a specific outcome as described below:

0

No errors (no output)

Bit 1

Warning on opening the key database.

Bit 2

Error on opening the key database.

Bit 3

Warning on getting the value of a key.

Bit 4

Error on getting the value of a key.

Bit 5

Warning on setting the value of a key. (only checked when -f is used)

Bit 6

Error on setting the value of a key (only checked when -f is used)

Bit 7

Warning on closing the key database.

Bit 8

Error on closing the key database.

So if the following number was returned 9 the user could figure out more detail by considering the bits: 00001001 The user would know that there was a warning on open and an error on get.

If a plugin name is given, checks will only be done on the given plugin. The returned values for a check on a plugin are returned as much simpler numbers.

Return values on plugin checking:

0

Everything ok. (no output)

1

No such plugin found or plugin could not be opened.

2

Plugin did not pass checks.

3

Plugin has warnings.

Please report any output caused by official plugins to https://git.libelektra.org/issues.

Since the error code is a return value, it is not automatically displayed to the shell. If the user wants to have the value printed, they must do so manually (by running a command such as echo $?).

EXAMPLES¶

To check the Key Database: kdb check

To check the Key Database and then print the result: kdb check followed by: echo $?

To check the Key Database including write checks: kdb check -f Note that this type of check may change configuration files.

To check the line plugin: kdb check line
