Wget resume broken download
The GNU Wget is a free utility for non-interactive download of files from the Web. It supports HTTP, HTTPS, and FTP protocols, as well as retrieval through HTTP proxies. Recently I was downloading Ubuntu Linux ISO (618 MB) for testing purpose at my home computer. My Uninterrupted Power Supply (UPS) was down. I started download with wget command:
$ wget http://ftp.ussg.iu.edu/linux/ubuntu-releases/5.10/ubuntu-5.10-install-i386.iso
Due to power supply problem, my computer rebooted at 98% download. Again, after reboot I typed wget:
$ wget http://ftp.ussg.iu.edu/linux/ubuntu-releases/5.10/ubuntu-5.10-install-i386.iso
However, wget restarted to download complete ISO image again. I thought wget should resume partially downloaded ISO file.
Command to resume file download with wget
After reading man page, I found -c option. It will continue getting a partially downloaded file. This is useful when you want to finish a download started by a previous instance of wget, or by another program.
$ wget -c http://ftp.ussg.iu.edu/linux/ubuntu-releases/5.10/ubuntu-5.10-install-i386.iso
