我想要一个6列(约130万行)文件,并根据第4列中的值复制这些行。输入:
public function simpanberkas()
{
$key = $this->uri->segment(3);
$this->load->model('model_pengaduan');
$query = $this->model_pengaduan->getdata($key);
if($query->num_rows>0)
{
foreach ($query->result() as $row) {
$data['file'] = $row->file;
}
}
$config['upload_path'] = './assets/file/';
$config['allowed_types'] = 'pdf|doc|docx|excel';
$config['max_size'] = '1000';
//$config['max_width'] = '2000';
//$config['max_height'] = '1024';
$this->load->library('upload',$config);
//$this->upload->initialize($config);
//$berkas = $this->input->post('berkas');
if(!$this->upload->do_upload('berkas')){
$error = array('error' => $this->upload->display_errors());
$this->session->set_flashdata('info',$error['error']);
}else{
$file_data=$this->upload->data();
$data['file']=base_url().'/assets/file/'.$file_data['file_name'];
}
$this->model_pengaduan->getupdate($key,$data);
redirect('pengaduan');
}
输出:
chr1 6209 6234 2 255 +
chr1 6686 6710 1 255 +
chr1 6755 6780 3 255 +
我发现this question非常相似,但当我尝试使用代码时,我无法维护我的列:
请原谅我的脚本无知。任何建议都表示赞赏。
答案 0 :(得分:6)
awk
救援!
$ awk '{c=$4; while(c-->0) print}' file
chr1 6209 6234 2 255 +
chr1 6209 6234 2 255 +
chr1 6686 6710 1 255 +
chr1 6755 6780 3 255 +
chr1 6755 6780 3 255 +
chr1 6755 6780 3 255 +
