Its quite easy actually, here's a little example

pawn Код:

//with ZCMD
CMD:help(playerid, params[])
{
    SendClientMessage(playerid,COLOR_ORANGERED,"Hello");
    return 1;
}
//with strcmp
    if (strcmp("/help", cmdtext, true, 10) == 0)
    {
        SendClientMessage(playerid,COLOR_ORANGERED,"Hello");    
        return 1;
    }

Now if the command you used have used params(E.G:/ban ID REASON), usualy in strcmp you use strtok, in ZCMD use sscanf, its a lot faster/easier too.
