    Hello sir
    how i can solve that task please send solution on my mail bainssandeep9@gmail.com

    Historically, the standard command for listing files, ls, did not provide facility to sort files by their size (in bytes). More recently, the ls command has received a new -S switch to sort files by size.
    Without using the new -S switch, develop a command pipeline to list files, sorted by their size.

    When sorting a text file containing both a header-line and data in multiple columns, we must be careful to not sort the header-line, too, else the header-line may end up in the "middle" of the lines of data.
    Consider the text file australian-universities.txt
    If we just sort it by either its 1st field (state name), then the initial header line will be incorrectly positioned in the middle of the output.
    Write a shellscript to sort text file, australian-universities.txt by the number of its international students, while keeping the header-line at the top of the output.
    [4 marks]
    Using a file of simple text to provide the input data, develop a command or shellscript to uniquely list all words found in the file (list each unique word once).
    We'll define a "word" to be any sequence of one-or-more alphabetic characters, the words "Hello" and "hello" are distinct words, and all other non-alphabetic characters should be ignored.

    Consider the following webpage: Perth, Western Australia February 2017 Daily Weather Observations which presents a number of weather observations from February. That webpage is written and presented in HTML (as you can guess from its use of fonts and colours), but HTML can be difficult to process using simple command scripts. Of greater interest to us are text-only equivalents providing the raw-data, here: February 2017 and February 2016.
    We've been told that the weather for February 2017 was more extreme than for February 2016 (in fact, that a number of records were broken).
    Based on your own definitions, write a shellscript to determine which corresponding weather observations in 2017 were more extreme than those in 2016.
