我写了一个 Perl 脚本:
#!/usr/bin/perl
use strict;
use warnings;
my $file_name;
my $ext = ".text";
my $subnetwork2;
my %files_list = ();
opendir my $dir, "." or die "Cannot open directory: $!";
my @files = readdir $dir;
sub create_files() {
my $subnetwork;
open(MYFILE, 'file.txt');
while (<MYFILE>) {
if (/.subnetwork/) {
my @string = split /[:,\s]+/, $_;
$subnetwork = $string[2];
}
if (/.set/ && (defined $subnetwork)) {
my @string = split /[:,\s]+/, $_;
my $file = $subnetwork . $string[1];
open FILE, ">", "$file.text" or die $!;
close(FILE);
}
}
close(MYFILE);
}
sub create_hash() {
foreach (@files) {
if (/.text/) {
open($files_list{$_}, ">>$_") || die("This file will not open!");
}
}
}
sub init() {
open(MYFILE3, 'file.txt');
while (<MYFILE3>) {
if (/.subnetwork/) {
my @string3 = split /[:,\s]+/, $_;
$subnetwork2 = $string3[2];
last;
}
}
close(MYFILE3);
}
sub main_process() {
init;
create_files;
create_hash;
open(MYFILE1, 'file.txt');
while (<MYFILE1>) {
if (/.subnetwork/) {
my @string3 = split /[:,\s]+/, $_;
$subnetwork2 = $string3[2];
}
if (/.set/) {
my @string2 = split /[:,\s]+/, $_;
$file_name = $subnetwork2 . $string2[1] . $ext;
}
if (/.domain/ || /.end/ || ($. < 6)) {
my $domain = $_;
foreach (@files) {
if (/.text/ && /$subnetwork2/) {
prnt { $files_list{$_} } "$domain";
}
}
}
elsif ($. >= 6) {
print { $files_list{$file_name} } "$_";
}
}
close(MYFILE1);
foreach my $val (values %files_list) { close($val); }
closedir $dir;
}
main_process;
该脚本根据 的内容在当前目录中创建文件file.txt
,然后再次打开这些文件。
然后它开始处理file.txt
并根据动态设置的文件名重定向行。
文件名的这种设置也是基于文件中的数据file.txt
。
我在这里面临的问题是重定向只到一个文件。这意味着文件句柄存在一些问题。
预期创建的所有文件都已完美创建,但数据仅进入其中一个。
我怀疑我在重定向时使用的文件句柄是否有问题。
有人可以帮忙吗?示例输入文件如下:
..cnai #Generated on Thu Aug 02 18:33:18 2012 by CNAI R21D06_EC01, user tcssrpi
..capabilities BASIC
.utctime 2012-08-02 13:03:18

AWBVAMOS="OFF"

..end
我面临的问题是在执行过程中:
> process.pl
Use of uninitialized value in ref-to-glob cast at process.pl line 79, <MYFILE1> line 6.
Can't use string ("") as a symbol ref while "strict refs" in use at process.pl line 79, <MYFILE1> line 6.
我能理解的问题是这一行:
print { $files_list{$_} } "$domain";
但我无法理解为什么!
我需要的输出是:
> cat NETSim_BAGBAG01.text
.set BAG01
AFRVAMOS="OFF"
AWBVAMOS="OFF"
ALPHA=0
AMRCSFR3MODE=1,3,4,7
AMRCSFR3THR=12,21,21
AMRCSFR3HYST=2,3,3
AMRCSFR3ICM=
AMRCSFR4ICM=
USERDATA=""
> cat NETSim_BAGBAG02.text
.set BAG02
AFRVAMOS="OFF"
AWBVAMOS="OFF"
ALPHA=0
AMRCSFR3MODE=1,3,4,7
AMRCSFR3THR=12,21,21
AMRCSFR3HYST=2,3,3
