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.

Note1: The Alice.txt file will only be used as part of an “In Lab” example/tutorial.

Note2: 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.

Instructions:

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 and lines with just 1 #) 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 following the comment marker.
   • For example:
     # some text becomes….
     # some text
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:
   • For example:
     [SVN] # Section: 1
     [……] # Section: 2
     etc.

Submit:

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.
