请在我的回答中找到更新的代码。我试图删除一个正在改变我的一些价值观的错误。我不是想让任何人为我编写代码，而是突出我的错误并提供良好的建议。

Answer 1

我要指出的是，您的示例代码中充斥着对我来说非常明显的错误，而且我只有约3个月的时间。

也许请阅读free book或llama book。

至于你的源代码，它不会像那样工作。我继续把它扔在一起做你想做的事，但我建议你学习更多关于perl的知识，这样你就可以更容易地解决这些问题。

#!/usr/bin/perl
use warnings;
open $newnums_fh, '<', '/home/job/newfile.txt' or die $!;
open $records_fh, '<', '/home/job/records.txt' or die $!;
open $newrecords_fh, '>', '/home/job/records_out.txt' or die $!;
while(<$newnums_fh>) {
    my @line = split(/\s+/, $_);
    my $employee_id = shift @line;
    my $employee_phone = pop @line;
    $phonenums{ $employee_id } = $employee_phone;
}
close($newnums_fh);
while(<$records_fh>) {
    my @line = split(/\s+/, $_);
    my $employee_id = shift @line;
    if(exists $phonenums{ $employee_id} ) {
        my $new_phone = $phonenums{ $employee_id };
        unshift @line, $employee_id;
        my $last_value = pop @line;
        my $old_phone = pop @line;
        push @line, $new_phone;
        push @line, $last_value;
        if(scalar @line == 9) {
            print $newrecords_fh join("\t", @line) . "\n";
        } elsif(scalar @line == 10) {
            print $newrecords_fh shift @line; #employee ID
            print $newrecords_fh "\t" . shift @line; #first name
            print $newrecords_fh ' ' . shift @line; #second name
            print $newrecords_fh "\t";
            print $newrecords_fh join("\t", @line) . "\n";
        } else {
            warn "Line is the wrong size! going to skip the entry!\n";
        }
    } else {
        next;
    }
}

Answer 2

这就是我解决这个问题的方法，它按预期工作，感谢大家的观看或评论

#!/usr/bin/perl
use warnings;
use strict;

my %employeehash;

open my $RECORD,'<','/home/maryh/Documents/employee.txt' || die $!;
open my $UPDATE,'<','/home/maryh/Documents/updatedphone.txt' || die $!;
open my $MODIFIED,'>','/home/maryh/Documents/xphone.txt' || die $!;


while (<$UPDATE>) {

   my ($emp_id, $phone) = split /\s+/;

   $employeehash{$emp_id} = $phone;

}
while(<$RECORD>) {

   chomp(my $line = $_);
   my $emp_id = substr($line,0,8);
   my $phone = substr( $line ,54,10);
   $emp_id =~ s/^\s+|\s+$//g;
   $phone =~ s/^\s+|\s+$//g;

 if (exists $employeehash{$emp_id} ) {

      $emp_id = $employeehash{$emp_id};
      $emp_id =~ s/^\s+|\s+$//g; 
      substr($line,54,21) =~ s/$phone/$emp_id/; 
      print "[$phone] got change to [$emp_id]\n"; 

  }

print $MODIFIED "$line\n" ; 

}

close $MODIFIED;
close $UPDATE;
close $RECORD;
