# removing single quotes from a string

# here are some options depending on what you want
# removes all quotes
$quotedstring =~ s/\'//g;

# removes beginning and end quotes
$quotedstring =~ s/^\'//;
$quotedstring =~ s/$\'//;

# comparing mac addresses

# I believe there is a better command
# called exists or something like that.
# but defined should work.
if ( defined $machash{$userrequest} )
{
return $machash{$userrequest};
}
