Thanks I got the solution. The code needs to be as below:

Code:
!/bin/ksh

echo "Please enter the string: "
read str
echo "Please enter the starting position: "
read start_position
echo "Please enter the number of characters to be extracted: "
read char_num

end_position=$start_position + $char_num

output=`echo $str | cut -c${start_position}-${end_position}`
echo "Output: "$output

Padre::Task::IntroduceTemporaryVariable(3pm)		User Contributed Perl Documentation	      Padre::Task::IntroduceTemporaryVariable(3pm)

NAME
Padre::Task::IntroduceTemporaryVariable - Introduces a temporary variable using PPI SYNOPSIS
my $tempvarmaker = Padre::Task::IntroduceTemporaryVariable->new( document => $document_obj, start_location => [$line, $column], # or just character position end_location => [$line, $column], # or ppi-style location varname => '$foo', ); $tempvarmaker->schedule; DESCRIPTION
Given a region of code within a statement, replaces that code with a temporary variable. Declares and initializes the temporary variable right above the statement that included the selected expression. Usually, you simply set "start_position" to what "$editor->GetSelectionStart" returns and "end_position" to "$editor->GetSelectionEnd - 1". SEE ALSO
