The problem: You are logged in to a terminal and you need to download a package, what do you do? Of course you can open up Chrome on your laptop, download the file, scp it over… but there is a better way.
The solution: Linux has a number of command line tools for web browsing and in this week’s Linux Tip we’ll go over a few tools to get you browsing the web like NCSA Mosaic never existed. For these examples I used a Raspberry Pi running Raspbian.
cURL is on of the most commonly used command line apps for downloading. To install it run:
#apt-get install curl
To download a file you must add -O or -o filename to prevent it from just printing to stdout.
|# curl -O https://github.com/curl/curl/archive/master.zip|
|% Total||% Received||%Xferd||Average||Speed||Time||Time||Time||Current|
|100 114||0 114||0 0||211||0||--:--:--||--:--:--||--:--:--||211|
The above example saves a file called master.zip, using the -o option you can provide a filename:
#curl -o example.zip https://github.com/curl/curl/archive/master.zip
wget is similar to cURL but I find it easier to use, by default it saves the file to the name of the file in the url. To install run :
#apt-get install wget
To download just run wget url:
# wget https://github.com/curl/curl/archive/master.zip

Lynx has been around for a long time, it is a full-on text-based web browser.
#apt-get install lynx
To browse a site run lynx url:
Which then opens a text-based browser which you can use to browse the website from your SSH terminal.
And wow you can now browse the web in a command line way.
These are just a few of the tools you can use to access web resources from the command line. Hopefully one of these can save you in a pinch. As always if you have any questions let us know through email@example.com.
