Perl中的回车

[英]Carriage return in perl

while(<FILE>)
{
    if (/progress/)
    {
        my @msgs = split(': ',$_);
        print "$msgs[1]";
        sleep 1;
    }
    local $| = 1; # to clear the buffer
    print "\r"; # carriage return
}

I am reading from the <FILE> for percentage progress, and print on the screen with carriage return but this doesn't seem to be working. 我正在从<FILE>读取进度百分比,并在屏幕上打印回车符,但这似乎不起作用。 Any idea or alternate way? 有什么想法或替代方法吗?

Because $msgs[1] ends in a newline. 因为$msgs[1]以换行符结尾。 chomp what you read from FILE . chomp您从FILE读取的内容。
