When attempting to use commands, I often get a kickback which looks like this

Router(config)#show ip dhcp pool
                ^
% Invalid input detected at '^' marker.

It does not matter what command it is, even "help" gives me this

Router(config)#help
                ^
% Invalid input detected at '^' marker.

What exactly is wrong with the second character? Is there something i'm missing?

What exactly is wrong with the second character? Is there something i'm missing?

There is no command that starts with the first character followed by the second character you typed based on the access level and mode you are on.

There are 2 access levels and 5 modes as indicated below. Some commands are not available depending on the access level and mode you are on.

As a security feature, Cisco IOS® Software separates EXEC sessions into two different access levels: user EXEC level and privileged EXEC level. User EXEC level allows you to access only basic monitoring commands; privileged EXEC level allows you to access all router commands. Privileged EXEC level can be password protected to allow only authorized users the ability to configure or manage the router. From privileged EXEC level, you can access all the command modes. There are five command modes: global configuration mode, interface configuration mode, subinterface configuration mode, router configuration mode, and line configuration mode.

Based on the extract you have shown (Router(config)#show ip dhcp pool), you are on configuration mode. The show command in not available in that mode. To access it, it must be preceded by the do command like:

Router(config)#do show ip dhcp pool

It does not matter what command it is, even "help" gives me this

To get help, you must type ?. The question mark is the help command not help.
