命令行perl脚本中的进度条 [英] progress bar in command line perl script

问题描述

我正在尝试在命令提示符下以％打印进度.但是它不能正常工作.

I am trying to print progress in % in command prompt. But it is not working properly.

我要将进度打印为::状态10％已完成 20％完成时将显示Status 20％Completed 在同一个地方，不在新行中.你能帮我吗?

I want to print the progress as :: Status 10% Completed when 20% will complete it will show Status 20% Completed in that same place not in new line. Could you please help me.

代码::

$count++;
$per=($count/$total)*100;
print "\nStatus:  $per Completed.\r";
sleep 1;

推荐答案

您可以执行以下操作:

use strict;
use warnings;

use Time::HiRes qw(usleep);
local $| = 1;

my @nums = 1 .. 20;

foreach my $c (@nums) {
  print "$c";
  usleep(100000);
  print ("\b" x length($c));
}
print "\n";
