kdb-plugin-check(1) – Perform internal checks

SYNOPSIS

kdb plugin-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. Prints additional information in case of errors/warnings.
  • -c, --plugins-config <plugins-config>: Add a plugin configuration in addition to /module.
  • -d, --debug: Give debug information. Prints additional debug information in case of errors/warnings.

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)
  • 11: No such plugin found or plugin could not be opened.
  • 12: Plugin did not pass checks.
  • 13: 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 plugin-check

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

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

To check the line plugin:
kdb plugin-check line
