我怎样才能得到它看起来像这样

How can i get it to look like this

downloading: TheFile.jpeg ...
25% [======>                              ] 614,424      173.62K/s    ETA 00:14

我知道卷曲能做到这一点，但是我需要得到wget来胜任这项工作。

I know curl can do that, however i need to get wget to do that job.

推荐答案

您可以使用下面的过滤器：

You can use the following filter:

progressfilt ()
{
    local flag=false c count cr=$'\r' nl=$'\n'
    while IFS='' read -d '' -rn 1 c
    do
        if $flag
        then
            printf '%c' "$c"
        else
            if [[ $c != $cr && $c != $nl ]]
            then
                count=0
            else
                ((count++))
                if ((count > 1))
                then
                    flag=true
                fi
            fi
        fi
    done
}

用法：

$ wget --progress=bar:force http://somesite.com/TheFile.jpeg 2>&1 | progressfilt
100%[======================================>] 15,790      48.8K/s   in 0.3s

2011-01-13 22:09:59 (48.8 KB/s) - 'TheFile.jpeg' saved [15790/15790]

此功能取决于 0x0d0x0a0x0d0x0a0x0d 的序列正在发送的进度条开始前的权利。此行为可能是依赖于实现的。

This function depends on a sequence of 0x0d0x0a0x0d0x0a0x0d being sent right before the progress bar is started. This behavior may be implementation dependent.
