配列からデータを返そうとしています。コードは以下のとおりです。
my %ignorables = map { $_ => 1 } qw([notice mpmstats: rdy bsy rd wr ka log dns cls bsy: in);
open my $error_fh, '<', 'iset_error_log';
sub findLines {
# Iterates over the lines in the file, putting each into $_
while (<$error_fh>) {
# Only worry about the lines containing [notice
if (/\[notice/) {
if (/\brdy\b/){
print "\n";
}
else {
print ",";
}
# Split the line into fields, separated by spaces, skip the %ignorables
my @line = grep { not defined $ignorables{$_} } split /\s+/;
# More cleanup
s/|^\[|notice|[]]//g for @line; # remove [ from [foo
# Output the line
@line = join(",", @line);
s/,,/,/g for @line;
print @line;
}
}
}
&findLines;
印刷すると、出力は次のようになります。

サブルーチンの外に配列を返すにはどうすればよいですか?
