To use the wget with proxy authentication, enter:
$ export https_proxy="https://server1.cyberciti.biz:3128/"
$ wget --proxy-user "USERNameHere" --proxy-password "PASSWORDHere" http://url-here
To use wget with a username and password for FTP / HTTP file retrieval, use:
$ wget --user=NAME --password='PASSWORD' url
To download a large file in size in background, enter:
$ wget -bqc http://path-to-freebsd-mirros-url/freebsd-lastest.iso
You can resume broken download with wget using the following syntax:
$ wget -c http://url/large.file.tar.gz
$ wget --continue https://url/file.iso
Anther usage is to archive a website using wget:
$ wget -nprk 'https://www.some-url-here/'
Creating ~/.wgetrc file
The $HOME/.wgetrc file act as an initialization file for GNU wget. You can store option in it. Here is my sample $HOME/.wgetrc file:
# sample file # Try ipv6 addresses first prefer-family = IPv6 # Setup proxy https_proxy = http://server1.cyberciti.biz:3128/ http_proxy = http://server1.cyberciti.biz:3128/ ftp_proxy = http://server1.cyberciti.biz:3128/ # Setup the credentials for both http/ftp user=vivek password=OhMyCoolPasswordHere |
