The wget program allows you to download files from URLs. Although it can do a lot, the simplest form of the command is: wget [some URL]. Assuming no errors, it will place that file in the current directory. If you do not specify a filename, by default it will attempt to get the index.html file.
This document descript how to set wget (The non-interactive network downloader) to download file via proxy.
wget Configuration files
Below are wget configuration files listed by their priorities:
- ~/.wgetrc: User startup file.
- /etc/wgetrc: Default location of the global startup file.
- Set proxy variables in shell for current pseudo-terminal.
- ~/.bash_profile: User specific environment.
- /etc/profile: System wide environment.
Note: If higher priority configuration is not set, then the very next priority configuration takes effective. For instance, ~/.wgetrc was not configured with proxy settings but /etc/wgetrc was configured, then proxy settings in /etc/wgetrc are the working proxys in wget.
Configuring wget proxy
1. Add below line(s) in file ~/.wgetrc or /etc/wgetrc:
http_proxy = http://[Proxy_Server]:[port] https_proxy = http://[Proxy_Server]:[port] ftp_proxy = http://[Proxy_Server]:[port]
2. Set proxy variable(s) in a shell manually:
$ export http_proxy=http://[Proxy_Server]:[port] $ export https_proxy=$http_proxy $ export ftp_proxy=$http_proxy
Verify the variable values using the “env” command.
$ env | grep proxy http_proxy=http://[Proxy_Server]:[port] https_proxy=http://[Proxy_Server]:[port] ftp_proxy=http://[Proxy_Server]:[port]
3. Add below line(s) in file ~/.bash_profile or /etc/profile:
# export http_proxy=http://[Proxy_Server]:[port] # export https_proxy=http://[Proxy_Server]:[port] # export ftp_proxy=http://[Proxy_Server]:[port]
