Step 1: Write a script to read all the lines from /usr/hello.txt. Keywords to research: open, close, while, chomp. Recommend using syntax like while (my $inputLine = <INPUT_FILE>) and chomp $inputLine;

Step 1.9: Decide if you want to act on each line as you read it, or if you want to slurp them all into memory and then loop through those. Note: Slurp technique will require familiarity with arrays and foreach.

Step 2: Write the code to read all the lines from the secondary (apparently export.cfg) files.

Step 2.9: Decide if you want to act on each line of these secondary files as you read them, or if you want to slurp them all into memory and then loop through those. Note: Slurp technique will require familiarity with arrays and foreach.

Step 3: As you go through the lines of those secondary files, extracting the report_cfg information is a Perl speciality (it's more or less what the 'E' stands for in the name "Perl", incidentally). As noted by others, use of the split statement is likely to be helpful here.

Is that enough to get you going?
