shibd takes the following command-line options.
-cpathname
Specifies the pathname of shibd's configuration file. Defaults to /etc/shibboleth/shibboleth2.xml or
the value of the SHIBSP_CONFIG environment variable, if it is set.
-dpathname
Installation prefix. Defaults to /usr.
-F Stay in the foreground. Normally, shibd backgrounds itself after starting up.
-f Force removal of listener socket.
-h Prints out a brief summary of the shibboleth options.
-ppathname
Specifies the pathname to use to write out the shibboleth PID file.
-wseconds
Seconds to wait for the background shibd to start up before the foreground process returns. If not
set, the default value is three seconds.
-t Validates the general correctness of the configuration. Not all problems can be detected this way,
but the chance of successful startup is high if the checking process does not log any errors.
-v Prints out the version string.
-xpathname
Specifies the XML schema catalog to use. Defaults to /usr/share/xml/shibboleth/catalog.xml.
