linux運維在操作linux過程中,用得最多的linux下載工具想必一定是wget,沒有看到哪一臺服務器沒裝過wget的,或許有人使用ftp下載，也有人使用多線程的axel以及ProZilla,毫無疑問這兩個工具都非常的出色,但是對於習慣使用wget的人來說顯得不適應,於是老外便開發了多線程版本的wget工具mwget,m表示multi多線程的意思.

# cd /usr/local/src/

# tar -xjvf mwget_0.1.0.orig.tar.bz2
# cd mwget_0.1.0.orig
# ./configure
# make
# make install

configure過程中如果出現如下錯誤，請安裝大於等於0.35版本的intltool

總結
mwget雖然功能偏少,並且無法完全替代單線程版本的wget，但是對於我們基本只是用wget簡單下載運維人員來說，mwget絕對是個完好的選擇.
