I think it's an AND you need, not an OR?

Code:
if [ "$USER" != "user1" -a "$USER" != "user2" -a "$USER" != "user3" -a ... ]

Alternatively, you can use a case statement:

Code:
case "$USER" in
 user1|user2|user3|...)  echo "do something";;
 *) echo "do something else"
esac

ppi::statement::null

PPI::Statement::Null(3) 				User Contributed Perl Documentation				   PPI::Statement::Null(3)

NAME

       PPI::Statement::Null - A useless null statement

SYNOPSIS

	 my $foo = 1;

	 ; # <-- Null statement

	 my $bar = 1;

INHERITANCE

	 PPI::Statement::Null
	 isa PPI::Statement
	     isa PPI::Node
		 isa PPI::Element

DESCRIPTION

       "PPI::Statement::Null" is a utility class designed to handle situations where PPI encounters a naked statement separator.

       Although strictly speaking, the semicolon is a statement separator and not a statement terminator, PPI considers a semicolon to be a
       statement terminator under most circumstances.

       In any case, the null statement has no purpose, and can be safely deleted with no ill effect.

METHODS

       "PPI::Statement::Null" has no additional methods beyond the default ones provided by PPI::Statement, PPI::Node and PPI::Element.

SUPPORT

       See the support section in the main module.
