If number of arguments =$ or $
Hi,

I am having a bit of trouble writing this.

I have the script working if I only use 1 of these but it's not working the way i need it to.

Basically more above the script i may or may not have a 5th variable defined. if i do it does a process before getting to the rest of the script. if there is not a 5th variable it skips that if statement and moves on.

Now the problem I am having is I need to have a check to make sure that the person using the script has 4 or 5 variables defined depending on which part of the script they are using.

When it checks how many variables it has it keeps complaining about this part:

Code:
        if [[ $# -ne 4 ]] || [[ $# -ne 5 ]]
        then

for some reason if there is a 5th variable the script is only trying to find 4 not or 4 or 5.

Can someone correct me here? I tried a few things and nothing seemed to do the trick.

service

service(8)						      System Manager's Manual							service(8)

NAME

       service - run a System V init script

SYNOPSIS

       service SCRIPT COMMAND [OPTIONS]

       service --status-all

       service --help | -h | --version

DESCRIPTION

       service	runs a System V init script in as predictable an environment as possible, removing most environment variables and with the current
       working directory set to /.

       The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT.  The  supported  values  of  COMMAND  depend  on  the
       invoked	script.  service passes COMMAND and OPTIONS to the init script unmodified.  All scripts should support at least the start and stop
       commands.  As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start  com-
       mand.

       service --status-all runs all init scripts, in alphabetical order, with the status command.

EXIT CODES

       service calls the init script and returns the status returned by it.

FILES

       /etc/init.d
	      The directory containing System V init scripts.

ENVIRONMENT

       LANG, TERM
	      The only environment variables passed to the init scripts.

SEE ALSO

       /etc/init.d/skeleton,
       update-rc.d(8),
       init(8),
       invoke-rc.d(8).
