If I was on my Mac I could probably pull up quite a few. One I'm fairly sure that uses perl is installers. (Not always, but often.) XCode makes it relatively simple to embed basic scripts (perl, shell, or otherwise) into a project. It wouldn't surprise me to find Perl is all kinds of odd applications, for some quick thing.

(Not that you can ever ignore what gets installed, but it's easier to protect the server if you keep the OS clean.) Are there OS functions that rely on perl? What sorts of things? Obviously the low-level kernel stuff like task switching, memory management, etc. aren't in Perl. But higher-level functions like cron jobs, startup scripts, installation scripts, etc. are often written in Perl. Unix admins had been using it for that sort of thing for years before web developers started using it. Installing a single perl may seem normal to users who are more accustomed to MacPerl and/or ActiveState's Perl for Windows, but it's *not* normal to install *nix perl that way. Sun even ships Solaris with two versions already installed, the latest version as /usr/bin/ perl, and whatever version they've verified their scripts against as / opt/sun/perl5.x.y/bin/perl. Are there nice directions somewhere for setting up a separate install? They're included with Perl. Actually, doing so is the path of least resistance, as the default is to install under /usr/local, which will not disturb Apple's perl. Also, how does CPAN module determine what's installed? It looks in @INC. sherm-- Cocoa programming in Perl: http://camelbones.sourceforge.net Hire me! My resume: http://www.dot-app.org

That will only show the files ending in .pl. Scripts use the #! line to determine the interpreter to run them with, not the filename extension. I was thinking, let's write a script to check the first lines. But I'm lazy. file /*bin/* | grep perl file /usr/*bin/* | grep perl gets everything in the usual places for system executables. Of course it misses utility scripts in odd places, including all those found by the locate *.pl command. Since I'm a little weak with one-liners and with File::Find, I should try to work up a one-liner that would do a recursive descent, and log out and back in as a user that can sudo so I can descend all the places my working user can't. But I'm lazy. ;-/
Re: problems with intel architecture
Not a one-liner and not even pretty, but since I needed the practice:
-
#! /usr/bin/perl
use File::Find;
@l = ( / );
sub w
{
if ( -d $_ )
{ my $dir = $File::Find::dir;
if ( system( file * | grep perl ) == 0 )
{ print *** from: $dir ***\n;
}
}
}
find( \w, @l );
-
Overkill.
Gets a lot of can't cd errors, of course, since I'm not running it as
root, and it takes a while to run, too.
Finds a bit more than scripts, too, so it really doesn't serve the
original question, Heh.

After about two hours of running (on an old clamshell iBook) and

without descending into /usr/bin.
Anyone have any ideas why?
