Give macOS’ Terminal a better ‘ls’

Anyone who uses Terminal will run the ls command to get a listing of files and directories. It’s built in to macOS’ BSD Unix foundation layer. It has one key limitation for me: it has no option to list directories before listing files. Read on to learn how to deal with this issue.

Using the Z shell on the Mac and Pi

When Apple released MacOS Catalina, it decided to switch the default command line shell from the Bourne Again Shell, aka bash, to the Z Shell, aka zsh. One reason for this was that Apple installs a rather old version of bash, 3.3.57, to allow it to include the software under a licence it’s happy with. This isn’t a problem that affects zsh, so Apple can bundle a much more recent release.

That was no problem for me, either, because I long ago used Homebrew to install an up-to-date version of bash, 5.0.17, and have been happily using in preference to the Apple one. To do so yourself, run brew install bash and then go to System Preferences > Users & Groups. Unlock if you need to then right-click on your name in the left-hand column and select Advanced Options…. Now highlight the Login shell: field and set the path to your preferred shell, in this case /usr/local/bin/bash. Afterwards, you can enter echo $SHELL to confirm the change.

Raspberry Pi Knowledgebase added

I’ve created a page containing simple sets of instructions for some key — and not so widely used — Raspberry Pi setup tasks. The goal is to have a single source that I (and anyone else) can check when they need to look up what they should do to perform a specific action: setting up Node.js, for example, or using Dropbox.

You can find the Knowledgebase here.

pdfmaker 1.1.0 released

I’ve just released version 1.1.0 of pdfmaker. You can view the source code here, and download an installer package here.

You can now select a single source file, not just a folder of files, and you specify the output PDF’s filename as part of the specified destination path, rather than separately (so the --name switch has been removed).

Alias is Your Friend

I regularly use ls -la to list directory contents on my Raspberry Pi. I often use ls -lah to also display hidden files. This week I wondered if there was a way to use either of these ls options by default. Well, there is.
