Zabbix commands not working on CLI

[redex]

I'm trying to write a simple command as:
zabbix-sever -R config_cache_reload

But keeps saying:
-bash: zabbix-server: command not found

It's happening while writing zabbix-snmp-gateway...

Why is not that file? How can I get them?

Try using the command "zabbix_server" instead of "zabbix-server". It's the difference between a hyphen and an underscore.
