Well yes, but
'~/perl5/bin' ne '/bin'
What does that mean?
In fact,
$ echo $PERL_LOCAL_LIB_ROOT
/home/choroba/perl5
My environment doesn't have that variable. How does it help isolate executables from CPAN? I guess it does help isolate core perl programs, like this:
#!/usr/bin/perl -l
use strict;
use warnings;
# List executables installed by Perl core
# List CPAN: https://perlmonks.org/?node_id=1217338
(my $bin = $^X) =~ s/.perl$//;
chomp(my @perl = `ls -l $bin`);
s/.*\s(\S+)$/$1/ for @perl; # filename
shift @perl;
chomp($_ = join "", `perldoc -uT perllocal`);
my @temp = (/EXE_FILES:\s([^>]+)/sg);
my @cpan = ();
for (@temp) {
my @x = split /\s+/; # filename(s)
s/^\S+\/// for @x; # remove path
push @cpan, @x;
}
my $perl = { map {$_=>1} @perl };
my $cpan = { map {$_=>1} @cpan };
my $core = {};
for (keys %$perl) { $core->{$_}++ unless $cpan->{$_} }
print $_ for sort keys %$core;
