in reply to assigning a name to every threads

I don't think you can list threads by ps -ef. As far as I know it only lists processes. Threads and processes are different.

If ps -ef shows two processes there are actually two processes, not the threads created by the mentioned snippet

PS: See man ps for thread listing options

    I am sorry... you are right..

    actually I am using forks module instead of the threads module. so the thread i am talking about is actually a process internally...

    Hope, I am clear now...

    any way Thanks samarzone ...

      In that case, you can simply assign to $0, which has been working fine for ages (on Linux, and for processes) — i.e. you don't need 5.13: 

      #!/usr/bin/perl

use forks;

my @procs;

for my $procname (qw(foo bar baz)) {
    push @procs,
        threads->new(
            sub {
                $0 = $procname;
                sleep 1;
            }
        );
}

system "ps fT -o pid,cmd";

$_->join() for @procs;

__END__
$ ./837477.pl
  PID CMD
10408 bash -rcfile .bashrc
 5278  \_ /usr/bin/perl ./837477.pl
 5279      \_ /usr/bin/perl ./837477.pl
 5280      \_ foo
 5281      \_ bar
 5282      \_ baz
 5283      \_ ps fT -o pid,cmd

      (the foo/bar/baz are your "forks-threads")
