There is a Tutorial on this which I'll add after but as a quick example.

Firstly in random code and I'll add again one of your after.

pawn Код:

if(if(!strcmp(cmdtext, "/test", true))
{
    return SendClientMessage(playerid, -1, "Hello World!");
}

Would be in ZCMD:

pawn Код:

CMD:test(playerid) //You do see some with Paramaterss but my command doesn't have any.
{
    SendClientMessage(playerid, -1, "Hello World!");
    return 1;
}

Your Code:

pawn Код:

if(!strcmp(cmdtext, "/disguise", true))//dialog which tells u about the spy class disguises
    {
        if(gClass[playerid] == SPY)
        {
             ShowPlayerDialog(playerid, 88, DIALOG_STYLE_MSGBOX, "{6EF83C}Spy - Disguise Kit:", "/England\n/Soviet Union\n/Taliban\n/United States\n/Australian Armada", "Disguise ","Exit");//Replace the team1,2,3 to your game teams name and colors, by /team1 or /team2 or / team3 the player gets disguise to enemy soldier but don't changes its team
             return 1;
        }

ZCMD:
// Your command doesn't use paramters

pawn Код:

CMD:disguise(playerid) //dialog which tells u about the spy class disguises
    {
        if(gClass[playerid] == SPY)
        {
             ShowPlayerDialog(playerid, 88, DIALOG_STYLE_MSGBOX, "{6EF83C}Spy - Disguise Kit:", "/England\n/Soviet Union\n/Taliban\n/United States\n/Australian Armada", "Disguise ","Exit");//Replace the team1,2,3 to your game teams name and colors, by /team1 or /team2 or / team3 the player gets disguise to enemy soldier but don't changes its team
             return 1;
        }
      return 1;
}
