Why do you use <STDIN> for the first two variables and <> for the third? 



opendir(DIR,".") or die "$!";
my @files=readdir DIR;

close DIR;

[download]

You have to use closedir to close a directory handle opened with opendir. 



open evein,$ever or die $!;
flock(evein, LOCK_EX) or die "Cannot lock - $!";  
while (<evein>)
{
chomp;
next unless length;
my ($key,$value)=split /===/,$_;
$result{$key}=$value;
}
close(evein);

The value of $ever doesn't change inside this loop so this code should be outside the loop where $ever is set. 



open evein,$ever or die $!;

[download]

You are trying to open 'events.txt' from a directory entered by the user.    If the user uses a relative path then your program won't be able to find it.    You should give the user more information than just the contents of $!. 



flock(evein, LOCK_EX) or die "Cannot lock - $!";

[download]

You can't LOCK_EX a file opened only for input, only for output. 



while(<fln>)
{
my ($line)=$_;

[download]

That is usually written as: 

while ( my $line = <fln> )
{
