Interesting, thanks. I think that the test if well dosed overall and that it can tell if someone does not know Perl.
Still I think that the phrasing of some questions is poor especially 41.
46 is ok. Years ago I trained mayself to read the /s modifier as superdot (a term used by J Friedl in "mastering regular expressions" IIRC) and the /m mod. as multi-line-anchors ;)
cheers

I don't think 41 was written correctly, and I read English fairly well. First none of the given answers work.

I think 41 is just wrong. You'd need a join or at least something like $,="\n";print @a to do what he is asking

Question #41 is poorly worded. For example, in "add them to the end of each entry" what does the "them" refer to -- the values (the array elements) or newlines? I thought the former when I read it but the answer indicates the latter was the intent.
With that said I believe that English grammar rules would hint at removing the "that do not contain newlines" part of the sentence to determine what the "them" refers to.
In which case the correct answer would be #1.
Update: Massive rewrite and added spoiler tags.

I think that by "each" you have to assume array elements

Thank you for pointing out the perl test. I just read it expecting to answer about 10-20 correctly. Imagine my joy when I correctly answered 42 of them. I guess the books are working for me. The monestary gets a lot of the credit too.
I got number 41 correct, but I see where one of the monks said it would not work, so I guess I'm confused too. Also, I answered fork instead of system to 25, so I have a little more studying to do in that area. Thanks again. | [reply] |

system implicitly forks and execs. If you want to "launch a child process to run a program", then fork is half the solution.

Your bias is showing.
system implicitly forks and execs.
On my computer, system does neither of those.
