Hacked up a new script to update multiple #git repositories (or just the one) non-destructively. Doesn't handle all use cases, of course, but useful for a lot of general cases. It stashes any currently uncommitted work, and updates multiple branches---which can be specified as arguments.

Would you like to get more out of bsddialog(3)?
BSDCan has a tutorial for that:

Introduction to TUI Programming using bsddialog with Benedict Reuschling
Thursday 2026-06-18: 13:00 - 16:00

Shell scripts have a bad reputation when it comes to usability and eye candy. Modern users find a blinking cursor on a a black screen leaves a lot to be desired when having to interact with a shell script. In this tutorial, we will create shell scripts that look like a GUI application: with buttons to press, input fields, select boxes and animated progress bars. These so called TUI (text user interfaces) programs still use shell script functionality as the backend, but are lightweight enough to not introduce too much overhead. Users will appreciate the ease of use of your shell scripts and you can rely on them to give you the data and visualizations you to need. At the same time, the TUI application is not difficult to learn and implement into existing scripts.

Are you looking to sharpen your Shell Scripting chops? Then you may be interested in the BSDCan Shell Scripting Tutorial for Beginners and Sysadmins with Mathias Eggers.

Anyone who works with BSD and other Unix- and Linux-like systems will sooner or later have to deal with the shell and shell scripts, e.g. automation of repetitive task or starting services in /etc/rc.d. Understanding scripts and how to meaningfully extend or rewrite them is the goal of this tutorial, which is mainly designed for beginners and sysadmins.

Simple shell scripts often consist of a sequence of arbitrary shell commands executed in a specific order to achieve a particular purpose. This is where the tutorial will begin, and I will then walk participants through the other components of a script using examples:

Variables

Sourcing

Control structures

Loops

In- and output redirection

Parameters and options

Functions

Testing scripts

From the tutorial the participants will get an impression of what could be achieved with the well-equipped toolbox the shell provides and use that knowledge for creating own scripts for their projects.

Participants should bring their own machines to try out the examples. I encourage everybody to ask questions and bring examples or problems from their daily work to the tutorial to foster a vivid discussion.

I've been writing shell scripts as part of my work since I got in contact with Unix in 1993 and have been teaching shell programming to apprentices for over ten years. This tutorial will be a shortened and in regards to rc-scripts extended version of that one-week course.

Any #Automator #ShellScript experts care to help?

I created the following script to copy the first 6 characters of a selected filename to the clipboard. But the clipboard item ends up with a hard return after the characters. Is there a way to put a stop to that?

Re earlier toot ... as soon as I'd finished dealing with #dependabot's PRs, I wanted to use the script to view other peoples' PRs against my code (there are only two that I've not dealt with because I'm a good boy, although one has been festering for 7 years because I'm a bad boy), and then to see all my PRs against other peoples' code that are still open. And so the script got just a teensy bit bigger.

Just optimised a #ShellScript for speed. This was definitely the right thing to do, rewriting it in #rust or #c would be silly.

#Poll: Curious about people's attitudes towards shell scripting.

Two part question:

1. Are you a DEVeloper (or working in a development-heavy role), OTHER-IT worker (such as a sysadmin, architect, anything in a non-development-heavy role), or NON-IT (accountant, doctor, whatever)
2. Do you HATE shell scripting, are you INDIFferent towards (or ignorant of) shell scripting, or do you LOVE it?
