Question

#!/usr/bin/perl

use strict;
use warnings;

my $file;
my @files;
my $parse;
my @files = <*>;
foreach $file(@files)
 chomp ($file);
{
 $parse = system qq(paste <(cut -f1,2,13 $file) <(cut -f12 $file));
}

"my" variable @files masks earlier declaration in same scope at Rast_seq.pl line 11.
sh: 1: Syntax error: "(" unexpected
sh: 1: Syntax error: "(" unexpected
sh: 1: Syntax error: "(" unexpected
sh: 1: Syntax error: "(" unexpected
sh: 1: Syntax error: "(" unexpected
sh: 1: Syntax error: "(" unexpected

请帮我解决这个错误。

Answer 1

将左大括号 { 移到 chomp;
之前 并删除第一个 my @files;
并更改 qq

的分隔符

my $file;
my $parse;
my @files = <*>;

foreach $file(@files) {
    chomp ($file);
    $parse = system qq#paste <(cut -f1,2,13 $file) <(cut -f12 $file)#;
}
