wget命令 -c断点续传

wget -O   wordpress.zip http://www.linuxde.net/download.aspx?id=1080

下载文件在指定位置并进行重命名

-O file
       --output-document=file
           The documents will not be written to the appropriate files, but all will be concatenated
           together and written to file.  If - is used as file, documents will be printed to standard
           output, disabling link conversion.  (Use ./- to print to a file literally named -.)

wget -c  断点续传,连续下

-c        --continue            Continue getting a partially-downloaded file.  This is useful when you want to finish up a            download started by a previous instance of Wget, or by another program.  For instance:

wget -c ftp://sunsite.doc.ic.ac.uk/ls-lR.Z
