无法在文件中搜索字符串并在另一文件中输出该行

问题描述

我是Perl的新手，并且已经写了代码在文件中一行的开头搜索"PERFORM"一词，并且相应的行应打印在另一个文件中.我还需要将PERFORM之后的字符串存储在数组中

Hi,

I am a newbie to Perl and have written a code to search for the word "PERFORM" at the start of a line in a file and the corresponding line should be printed in another file. Also I need to store the string after PERFORM in an array

use strict;  
 se warnings; 

open FILE1, "<Test3.txt" or die "Cannot open File1.txt!";
open FILE2, ">File2.txt" or die "Cannot open File2.txt!";


while (my $string=<FILE1>) {
	
	if($string =~ m/^PERFORM\s*/)
	{
	print (FILE2 "$string\n");
	}
	

}
close FILE2;
close FILE1;

但是我也得到以"*"和"END-PERFORM"开头的行的输出.

预先感谢.

But I get output of lines starting with "*" and "END-PERFORM" also.

Thanks in advance.
