Thanks, but what when i want to put "load" data from data.txt instad of keyword like LIKE???? I mean for example for $i in "here i will put name of the file etc" is that possible?
What you are asking for is a very persistently repeated beginner shell programming mistake called "Dangerous Backticks".
Quote:
(From the URL above)
A special idiom to pay attention to, because it's basically always wrong, is this:
Apart from the classical Useless Use of Cat here, the backticks are outright dangerous, unless you know the result of the backticks is going to be less than or equal to how long a command line your shell can accept. (Actually, this is a kernel limitation. The constant ARG_MAX in your limits.h should tell you how much your own system can take. POSIX requires ARG_MAX to be at least 4,096 bytes.)
It wastes time, memory, external calls, and subshells to slowly and unreliably almost do what you wanted. The read shell builtin actually reads lines, running externals in backticks do not -- they split on any spaces at all.
Hi all,
Just a little question relative to signals.
I know that if an application is in the sleep state, When a signal is catched, it will be processed by the handler. But what happens if it's processing something? Does the processing stops??

uri::url
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 compared to the "URI" class interface exist:
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 subclasses 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 with 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
