刪除 wget 的每比特日誌

我有一個 php 腳本，它可以生成 bash 命令到 wget 文件。我正在嘗試使用以下方法記錄 wget 活動：

--directory-prefix='xxx' --append-output='xxx.txt' -c -t0 -S"

但是由於這個原因日誌太大了：

0K .......... .......... .......... .......... ..........  0%  110K 14m5s
50K .......... .......... .......... .......... ..........  0%  230K 10m24s
100K .......... .......... .......... .......... ..........  0%  272K 8m49s
150K .......... .......... .......... .......... ..........  0% 41.7K 15m53s
200K .......... .......... .......... .......... ..........  0%  173M 12m42s
.
.
.
92800K .......... .......... .......... .......... .......... 99%  156K 0s
92850K .......... .......... ...                             100%  139K=7m56s

我可以刪除上面的輸出並讓 wget 只得到這個：

如果我只對真實的細節感興趣，我只是因為這個日誌而消耗了太多的空間。

-nv您可以使用該選項關閉大量輸出。如果這對您來說過於冗長，您可以使用--progress選項調整進度報告，但我認為您不能完全刪除它。dot:mega報告樣式每 64kB 生成一個點（而不是預設的每 1kB 一個點）。

wget --progress=dot:mega …

最近的版本也支持dot:giga（每 1MB 一個點）。
