It has tons of Add-on’s that won’t let you go with additional software downloading on computer.This series is an excerpt from the first chapter of my upcoming book “Scripting macOS” which will teach you to use and create shell scripts on macOS.Firefox is more than a browser. Mozilla Firefox is one of the top web browsers for Mac that features fast in browsing and very close competitor for Google Chrome. Mozilla Firefox is perfect for casual searches as well as more complex queries.Mozilla Firefox Browser for Mac.

Firefox Browers Install The LatestFinally, they need to copy the Firefox application from the virtual disk to the Applications folder.When we want to automate the task ‘Download and Install Firefox,’ we have the following steps: Then the user needs locate the dmg in the ~/Downloads folder and open it to mount the virtual disk image. Internet browsers are notorious for eating your computer’s resources.Follow this blog or the Twitter account for updates on the book’s progress! Download and Install FirefoxTo further illustrate the progress from the idea of a workflow to a working script, let us look at another, more involved example.To download and install the latest version of Firefox a user has to go to the Firefox website and download the latest version, which will come as a disk image (dmg) file. Arguably, Mozilla offers the fastest speeds available for browsing the web.To save the download to a file, we can use the -output option with a file name. As always, you can find a detailed description of the curl command and its options in the curl man page.The URI to download the latest Firefox isHowever, when you try to curl this URI, you only get the following: > curl ""This is a re-direction, that is commonly used to have a single URI, that is redirected to different final URIs, so that when the software updates, the same URI always returns the latest version.We can tell curl to follow these redirections with the -location option.By default, the curl command will output the download to standard out. We will only discuss the few options that we require for our task here. The curl command is very complex and has many options. Download from the Command LineYou can use the curl command to download data in the command line. Reformatting my passport wd for windows and mac file transferFor that reason, I recommend using the long, descriptive options in scripts.

The short options for –location and –output are -L and -o.Short options are convenient in the interactive shell, as they save typing and reduce the potential for typos. We can use this as our first step: #!/bin/zshNote: Like many other command line tools, curl has short and long options. The last line ends with the path to the mounted virtual disk /Volumes/Firefox.By default, you can see the mounted volume in Finder.

This is also a very powerful command with many verbs and options. open the newly installed Firefox app after installation delete the downloaded disk image at the end You can try to adapt this script to work with some other software you can download as a disk image. The script should be able to detect the failure before it overwrites the installed, functional Firefox application.We will get to this kind of error handling later.Nevertheless, this script is already useful in its current form. In our example, imagine the download fails. Lists of Commands—ConclusionWe have been able to automate a fairly complex workflow with a script of four commands.To be perfectly honest, this script (as well as all the others we have built so far) is not complete yet.A ‘proper’ script needs to be able to react to errors that occur.
