Is nagios.cfg in this directory?

yes it is in the /usr/local/nagios/etc

lets change the command to copy the whole thing and paste command in terminal

still getting the same error message

lets step back because this is taking more effort trying to run this script than necessary..

Can you verify your config
If so, there is nothing else to do.

If you get an error about an invalid config option then we likely need to remove it from /usr/local/nagios/etc/nagios.cfg

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

Reading configuration data...
Read main config file okay...

***> One or more problems was encountered while processing the config files...

Check your configuration file(s) to ensure that they contain valid
directives and data definitions. If you are upgrading from a previous
version of Nagios, you should be aware that some variables/definitions
may have been removed or modified in this version. Make sure to read
the HTML documentation regarding the config files, as well as the
'Whats New' section to find out what has changed.

now we need to see /usr/local/nagios/etc/hosts.cfg

hostsfile as requested
