Where the option argument, plugin
is the plugin that a user wants to check. Use -c

.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:
-f
is used)-f
is used)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:
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 $?
).
