Question

我很难以一致的格式放置数组列。我有以下输出：

Mon,Jun,25,14:39:29,2012,971,29,0,25,0,0,0,4,Mon,Jun,25,14:39:29,2012,25,mod_was_ap22_http.c

我想要显示的列： DAYOFWEEK，月，日，时，年，RDY，BSY，RD，WR，嘉，日志，DNS，CLS，请 AP22，SM22，ApacheModule

目前粗体列不是那个顺序（其余的都是正确的）。每行与该格式不一致。该行有时首先是ap22，有时首先是sm22，有时没有或全部是三个模块。模块前面的数字与模块有关。如何将数据移动到一致的格式？

请注意，每行中的第二个日期mod_was_http.c，mod_sm22.cpp和ApacheModule.cpp将在最终数组中删除。

到目前为止，这是我的代码：

# This program parses a error log for necessary information and outputs in CSV format.

# chunks of your input to ignore, see below... 
my %ignorables = map { $_ => 1 } qw([notice mpmstats: rdy bsy rd wr ka log dns cls bsy: in);  

# 3-arg open is safer than 2, lexical my $fh better than a global FH glob 
open my $error_fh, '<', 'iset_error_log';   

sub findLines {
    my($item,@result)=("");
    # Iterates over the lines in the file, putting each into $_ 
    while (<$error_fh>) {      

        # Select only those fields that have the word 'notice'
        if (/\[notice/) {          

            # Place those lines with the word 'rdy' on the next line
            if (/\brdy\b/){
                push @result,"$item\n";
                $item="";

            }
            else {
                $item.=",";
            }

            # 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 unnecessary elements from the array

            # Output the line.  
            @line = join(",", @line);          
            s/,,/,/g for @line;
            map $item.=$_, @line;
            }
        } 
        @result
    }  

my @array = &findLines;
foreach $line (@array){
    print $line; #This is where I would like to organize the lines if possible.
}

我的输入文件如下所示：

Answer 1

在使用连接将它们重新转换为一行文本之前，您可能希望在仍然进行拆分时对列重新排序。

你只需要进行交换。

# 0        ,1    ,2  ,3   ,4   ,5  ,6  ,7 ,8 ,9 ,10 ,11 ,12 ,13  ,14  ,15
# DayOfWeek,Month,Day,Time,Year,Rdy,Bsy,Rd,Wr,Ka,Log,Dns,Cls,AP22,SM22,ApacheModule
#
# Sometimes the last 2 fields are missing and 13 comes before 14 and 15 in the 
# input, so fix that.
if (@line < 16) {
    push @line, '', ''; # or whatever you want for blanks
}

@line = @line[0..12,14,15,13]; # rearrange the array

此外，如果使用空字符串（s/,,/,/g）作为空字段，则正则表达式''将打破此问题。缺少最后一个字段的短线将重新缺少错过正确的13和14字段。

根据此处和之前提出的问题类型，我强烈建议您获取Modern Perl（可供下载或购买）或Learning Perl的副本，以便更好地掌握语言整个。我最近阅读了很多前者，并且很喜欢它，并从后者的早期版本中获得了我最初的Perl知识。
