Below is what i intend to do.
1. I stored some data in a file.
2. I intend to read the file line by line and store each line of data into a variable, so that i can used it later.

In a shell that has arrays (e.g., bash, ksh93):

Code:
IFS='
'
file=( $( cat "$FILE" ) )

However, that will probably be no better than reading the file when you need it.

If you need to store it in variables that depend on the contents of each line:
Code:
while IFS= read -r line
do
   ## check for criteria and store in variable here
done < "$FILE"

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 SEE ALSO
