Quick question regarding if statement

Hi,
I'm trying to write an if statement that will check the USER parm against some text but I'm not quite sure how to use the or switch in the statement.. Can anyone help me out?...

If someone could also let me know when to use ( or [ in the statement.. Can never figure that out...

Code:
if (( $USER != "user1" || "user2" || "user3" || "user4" ))
then
  print ""
  print "Incorrect username passed in"
  print ""
  print  "Please check the spelling of $USER..."
  print ""
  exit 1
fi


Thanks,
Jaz

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. AUTHOR
