Re^2: How to remove white space and more than a particular number of new lines!

Thank You mr_mischief , it helped me a lot...

but this code is affecting all the lines, I want to keep a line as it is if it contains anything other than white space and tabs.

For example I am changing the input and output to this,

Input,

 TEST1         fgdfgb

Test2      dlfgndkflgbn

test3   /,g;dhjzmpa h7rg tRruber 

Test4   ';gfojmd ofimt  lj   kjbkhb

+) or interface(s) that Mimecast provides or sells.  This could be a s
+ervice delivered through the cloud, or installable software that cust
+omers will use on their computers, SmartPhones, tablets and similar d
+evices.

                                     

                                    

                                        



                                     

For each product under your remit, you will have a good understanding 
+of the competitors in the market and their pricing, as well as the re

If this sounds like you, then please read onĀ&#133;..



                           

    



You will be required to spend time sharing ideas and product concepts

Your role will see you managing development through the entire develop

You were shown two alternatives. Which one did you use? (Hint: You must copy/paste directly from the shell window where you ran the command.) What actual output did you get? (Again, use copy/paste.) BTW, it's not really clear that the "desired output" is consistent with the OP description of what you're trying to do. Please be more explicit in the explanation, or more careful about presenting the "desired output". Also, it looks like your input contains some non-ASCII characters. Do you know what sort of character encoding is being used? If it's UTF-8, you'll want to add '-C31' as the first command-line option on the perl command line that mr_mischief gave you (i.e. `perl -C31 -e …` (but if it's something other than UTF-8, you'll want to handle encoding conversion).
