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.
