Tab Completion for autopkg

Tony Williams aka ‘honestpuck’ has built a script to enable tab-completion for autopkg in bash.

This means that you can type

$ autopkg s⇥

(where ⇥ is the tab key) and it will autocomplete to

$ autopkg search 

This will also work for recipe names:

$ autopkg run BBEdit⇥⇥  BBEdit.jss       BBEdit.pkg       
BBEdit.install   BBEdit.munki     

This is really useful. Auto-completion not only saves on typing, but helps to avoid errors.

Installing autocompletion in your profile

Tony has provided instructions on how to install the script with brew. However, it not hard to install this manually in your .bash_profile or .bashrc. First, clone the github repository on to your system (I keep all projects like this in an un-creatively named ‘Projects’ folder):

$ cd ~/Projects
$ git clone

This will download the project to autopkg_create. The file we need is the autopkg file inside that folder.

Then add the following lines to your .bash_profile or .bashrc:

if [[ -r "$HOME/Projects/autopkg_complete/autopkg" ]]; then
    source "$HOME/Projects/autopkg_complete/autopkg"

You will need to adjust the path if you are using a different location. Basically these lines say: if this file exists and is readable, then read and interpret it as bash source. Since you need to define functions in the context of the shell, you need to `source` the file, rather execute it as script. (When you run the the file as a script, the functions will be defined in the context of the script, and then ‘forgotten’ when the script ends.)

Save your new profile and open a new Terminal window or type

$ source ~/.bash_profile

to update an existing shell.

Thanks again to Tony Williams, this is very useful!

Typefaces for Coding and Terminal

Since the previous posts were about customizing the shell for shell I thought I’d update an older post and look at some monospaced fonts suitable for Terminal and text editors to get a change from Menlo.

Not so serious, but fun…

C64 TrueType is a fun addition at the end. As the name implies this font recreates the 8-pixel characters from the C64. Together with some extra settings in Terminal and your bash_profile you can take your terminal back to the 80s.

If you have been following along my lose series on Terminal in macOS, this serves as a nice example of some more exotic Terminal customization.

MacSysAdmin 2017 Conference Open for Registration

You can now register for the MacSysAdmin Conference in Göteborg (Sweden) which will go from October 3-6.

It is a great conference and I have wanted to go for years, but never managed to make it. The list of speaker has been and is really very impressive.

So I am very proud to announce that not only will I be attending but also presenting a session on macOS bash scripting this year! (so literally a session on ‘Scripting OS X… macOS’)

Looking forward to seeing you all there!

Mac Pro: Signs of Life

This week’s big surprise is that Apple has let out some early news that they are working on a new Mac Pro. Even more interesting than new hardware is (for me) that Apple is trying to re-assure the pro and prosumer market that Apple cares about them.

Micheal Tsai has a great summary post.

On Viewing `man` Pages

When you frequently use Terminal, you will use man pages. They contain tons of useful information on most of the tools and commands you use on the shell.

However, the man command’s user interface was designed for terminal output decades ago and does not really integrate well with the modern macOS UI. When you run the man command the output will take over your current Terminal window and scrolling through long man pages can be tedious.

Normal man page in Terminal


However, on macOS you do not have to man like it’s 1989.

First solution is to use

$ open x-man-page://ls

instead of man. This will open the man page in a new yellow Terminal window, so you can still see what you are actually doing, while reading the man page. If the yellow is just too annoying for you, you can change the look of the window by changing the ‘Man Page’ window profile in the Terminal Preferences. Since this window shows the entire man page, you can scroll and even use ‘Find’ (Command-F) in this window.

The beautiful yellow x-man-page window

Since typing this open command is a bit awkward, you can add a function to your bash profile or bashrc file:

function xmanpage() { open x-man-page://$@ ; }

Note: You could use xman here. However, that will conflict with another command when you have X11/XQuartz installed.

You can also put ‘x-man-page:’ URLs in other applications, such as emails or chat applications. However, not all applications will recognize URLs starting with x-man-page: as URLs, so your results may be mixed. It does work in Slack, even though Slack is skeptic of the links:

Slack will warn you about unusual links

Taken from Context

In Terminal, you can open a man page from the context menu. Simply do a secondary (ctrl/right/two-finger) click on a word in a Terminal window and choose ‘Open man Page’ from the context menu. This will open the man page in a separate window, like opening x-man-page URLs.

Open man Page in the Terminal context menu

man Page with a (Pre)view

Back in the early days of computing you could (or had to) convert man pages into postscript output, so they would look nicer when printing. These options are still present and we can (ab)use them to show a man page in Preview. (Please don’t waste paper printing man pages.) The command for this is:

$ man -t ls | open -f -a "Preview"
Preview showing a man page

The -t options pipes the man page into another tool (groff) to reformat it into pdf which we then pipe into open and send to the Preview application. (More on the open command.) If you use this more frequently, you want to create a function for this in your bash profile or .bashrc:

function preman() { man -t "$@" | open -f -a "Preview" ;}

Text Editors

You can also send a man page to a tex editor. Before you pipe the output into a text editor, you have to clean it up a bit:

$ MANWIDTH=80 MANPAGER='col -bx' man $@ | open -f

This will open in TextEdit. If your favored text editor can receive data from stdin, then replace the open -f with its command. For BBEdit, this will work great:

$ MANWIDTH=80 MANPAGER='col -bx' man $@ | bbedit --clean --view-top -t "man $@"

And again, if want to use this method frequently, create a bash function for it.


The ManOpen application has been around for a long, long time, but amazingly, it still works on macOS Sierra. It will also display man pages in a separate window. The main advantage MacOpen has over the other solutions here is that it will automatically detect other commands and highlight them as hyperlinks to their man pages. There is also a command line tool, confusingly called openman to open the app directly from the Terminal.


You can also create an Automator Service for this. Then you can open man pages from (nearly) any application with a keystroke or from the context menu. I described this in an older post on man pages.

Upgrade to the latest macOS that is compatible with your Mac.2
Requires macOS Sierra 10.12.4 or later. Reinstall the macOS that came with your Mac, or the version closest to it that is still available.

News Summary: Week of 2017-03-24

Back when I was a Server Sales Engineer I would make a weekly summary for other Field Engineers and customers on server and admin related news.

Thought I might try this tradition, again. Welcome to the first Scripting OS X Weekly News roundup!

On this Blog

I published my second book ‘Property Lists, Preferences and Profiles for Apple Adminstrators’! (PR3 for short) Get the details in the pre-sales announcement and download the book here!

I also posted an update to the Packaging book last week. It got a new cover to fit with PR3 and some internal changes and corrections. I also added an extra page with the version history for all the update details. If you have purchased the book already, iBooks should have notified you of the update. If you have been ignoring that red batch on the iBooks app, go check it out!

If you have the books and like them, please leave a review on iBooks store!

And then I continued with the articles on the Terminal and command line with a new post: [Terminal – the ’’ marks the spot.

If I missed anything, let me know in the comments, twitter or the MacAdmin Slack forum!

Apple acquires Workflow app

You’ve probable heard it already: Apple has bought the Workflow application. The developers will keep working at Apple and the Workflow app is now offered for free on the AppStore, although with a few interesting changes.

Workflow has always been one of those apps that would have liked to get into. However, as an admin, my workflows center on macOS and Unix. You cannot build packages on iOS. Even iBooks Author only exists on macOS. As much as I like the iPad and iOS it has been relegated to secondary device because of the focus of my work.

Still it will be interesting to see how Apple will integrate Workflow with iOS and the Apple applications. I am looking forward to it.

If you now want to catch up with what Workflow is all about, you can’t do much better than Frederico Viticci’s articles on MacStories.
