Download file using bash

One of the most popular command line tools for downloading files from the internet is Wget. It also provides users with a variety of features ranging from recursive downloading to playing and pausing the downloads as well as limiting its bandwidth.

Moreover, it is cross-platform which gives it quite the edge over many other command line downloaders as well as graphical downloaders. Wget usually comes pre-installed with most of the Linux Distributions. It is to be noted that the command given above is for only Debian based Linux systems such as Ubuntu.

If a user has a Red Hat Linux system such as Fedora, then the user needs to enter the following command into the command line:.

As mentioned before, Wget has multiple features incorporated inside of it. The most basic operation that Wget offers to users is downloading files by simply using its URL. This can be done by inputting the following command into the terminal:. Let us show an example to further clarify this. I guess it's mathematically possible that my rand command could assign overlapping numbers to two files but, given that the default range rand uses is between 1 and 32,, that's a risk I'm willing to take.

And yes, cheating or not, this is a valid solution and worth an upvote : — ilkkachu. Taking the " just Bash and nothing else " strictly, here's one adaptation of earlier answers Chris's , 's that does not call any external utilities not even standard ones but also works with binary files:! Isn't echo a standalone -non shell- binary? Bash has echo and printf as builtins it needs a builtin printf to implement printf -v — ilkkachu.
