Thank you very much, BubbaJoe.

I search more and found some link

InformIT: Solaris 10 System Administration Exam Prep: Managing System Processes > Using Signals
Safari Books Online - 0789729229 - Solaris? 9 Training Guide (CX-310-014 & CX-310-015): System Administrator Certification

Code:
Table 5.12. Signals Available Under Solaris
Signal	Number	Description
SIGHUP	1	Hangup. Usually means that the controlling terminal has been disconnected.
SIGINT	2	Interrupt. The user can generate this signal by pressing Ctrl+C or Delete.
SIGQUIT	3	Quits the process and produces a core dump.

As far as I understand, TRAP 1 means that it will detect the signal that I was disconnected from the system by hangup the modem (I think because the dial-up or ADSL connection is lost).

Why do we want to use TRAP 1?? If any user was disconnected because hang up then that user can't access the server isn't it?

Anybody could tell me which value I should set for TRAP in etc/profile and /.profile of each user please?

URI::URL(3)						User Contributed Perl Documentation					       URI::URL(3)

NAME
URI::URL - Uniform Resource Locators SYNOPSIS
$u1 = URI::URL->new($str, $base); $u2 = $u1->abs; DESCRIPTION
This module is provided for backwards compatibility with modules that depend on the interface provided by the "URI::URL" class that used to be distributed with the libwww-perl library. The following differences exist compared to the "URI" class interface: o The URI::URL module exports the url() function as an alternate constructor interface. o The constructor takes an optional $base argument. The "URI::URL" class is a subclass of "URI::WithBase". o The URI::URL->newlocal class method is the same as URI::file->new_abs. o URI::URL::strict(1) o $url->print_on method o $url->crack method o $url->full_path: same as ($uri->abs_path || "/") o $url->netloc: same as $uri->authority o $url->epath, $url->equery: same as $uri->path, $uri->query o $url->path and $url->query pass unescaped strings. o $url->path_components: same as $uri->path_segments (if you don't consider path segment parameters) o $url->params and $url->eparams methods o $url->base method. See URI::WithBase. o $url->abs and $url->rel have an optional $base argument. See URI::WithBase. o $url->frag: same as $uri->fragment o $url->keywords: same as $uri->query_keywords o $url->localpath and friends map to $uri->file. o $url->address and $url->encoded822addr: same as $uri->to for mailto URI o $url->groupart method for news URI o $url->article: same as $uri->message SEE ALSO
