Hello,
Here is a link with a list of commands :
http://www.ncat.co.uk/net_lib/ncat%20ccna%20cheat%20sheet.pdf
I would recommend using the "?" on the command line at anytime you would like to see a complete list of available commands.
For example:
Router#?
Exec commands:
<1-99> Session number to resume
auto Exec level Automation
clear Reset functions
clock Manage the system clock
configure Enter configuration mode
connect Open a terminal connection
copy Copy from one file to another
debug Debugging functions (see also 'undebug')
delete Delete a file
dir List files on a filesystem
disable Turn off privileged commands
disconnect Disconnect an existing network connection
enable Turn on privileged commands
erase Erase a filesystem
exit Exit from the EXEC
logout Exit from the EXEC
mkdir Create new directory
more Display the contents of a file
no Disable debugging informations
ping Send echo messages
reload Halt and perform a cold restart
--More--
At anytime you can use the "?" after beginning a command to help you complete the command
For example:
Router#show ?
aaa Show AAA values
access-lists List access lists
arp Arp table
cdp CDP information
class-map Show QoS Class Map
