Question description

Hello, I'm looking for help to do this lab, because I'm not that good at PERL programming language. I tried my best but nothing work. The submission is two hrs from now. can you help me do it please ?


Attached Files:


perl example from the class.txt  ==>this is help to use it as a template please 

Create a Perl program that is simply a loop over a set of "Regular Expressions" that perform the tasks described below. Use the attached file SampleConfig.txt as input.  

Note: Though this is a bit assignment is a bit contrived, it does represent the types of actual text manipulations that might be performed over many large files.


Using the attached SampleConfig.txt file, provide a Perl regular expression for each of the following tasks:

  1. Remove any leading or trailing space from each line.
  2. Replace all of the occurrences of a full line of # characters (ignoring leading or training spaces) with the following: # ---------- #
  3. Change any URL ending in .htm to end with .html
  4. For any set of multiple words following an equal sign (=),  place what follows the equal sign in quotes.
    • eg: a = bcd efg  becomes a = "bcd efg"
    • eg: a = bcd  remains  a = bcd
  5. Add a semicolon (;) to the end of every line.
  6. Every line beginning with a comment marker (#) and containing additional text should have one (and only one) space folling the comment marker.
  7. Replace any pattern in the form of [__UPPER-CASE CHARACTERS__] with (lower-case characters)
    • ie: Open square bracket + two underscores + upper-case text + two underscores + close square bracket
    • eg:[__SOMEDATA__] becomes [somedata]
  8. Follow every "config section" with a comment that indicates the current section count:
    1. For example:
         [SVN]  # Section: 1
      ......]  # Section: 2


  1. A file containing the Perl code to fulfill the above requirements

  2. A version of the SampleConfig.txt file incorporating all of the above changes
