@Zanna So I did get additional perl interpreters installed on the Mac OS X 10.4 system.

Both lower and higher numbered perls installed through perlbrew recognized that m was in the character class [@-~]. Only the system-provided perl hd the problem.

Then I asked a friend of mine who has the same version of macOS as that OP... and she did not have the problem with the system-provided perl, so I wonder if I've found a separate problem from what that OP had (assuming they did actually encounter a problem that required them to install a newer/different interpreter).

So I decided to try it on FreeBSD, which unlike macOS I can easily install any version of. Really this is mainly for a different aspect of the problem: it's unclear to me precisely what -k does as described in that manpage.

> -k Log keys sent to program as well as output.

hmm... that's not a very clear description...

My friend who, like that OP, runs 10.11.6 El Cap, ran script on an interactive program without issuing -k and her input did totally appear in the typescript.

Now I have FreeBSD running in a virtual machine and... the default install doesn't come with perl!

blimey! hard to imagine how they manage

@Zanna I have heard, repeatedly, from several people, and also multiple books, some by experts, that perl is required by POSIX. But, looking now, I cannot actually find a primary source that supports this contention.

No perl.

Perl5 is leaving the base system for 5.0 and after!

Maybe I am wrong that I have heard that? (??)

Definitely not required by POSIX: encrypted.google.com/…

Whoa, how long has it been since I've used FreeBSD?

I ask this because I'm surprised that the default installation (a) doesn't have Perl and (b) does have virtual consoles!

I should not be surprised by these things.

Whoa, and now it actually does have seq installed as well as jot!

:)

I've never used FreeBSD, but the Linux meetup I went to when I was living in London had a regular who used FreeBSD (not Linux!) and I enjoyed talking to him. Although not always about Unix-like matters

Running getent passwd as root on FreeBSD dumps the hashes!
