A huge part of programming in general is learning how to troubleshoot something, not just having someone else fix it for you. One of the basic ways to do that is by tracing. Not only can this help you figure out what your script is doing and how it's doing it, but in the event that you need help from another person, posting the output can be beneficial to the person attempting to help.
This is a little tutorial that I found in my search to learn how to use getopt (mind: not getopts, which is a completely different thing). I want to share it here because I find it refreshingly to the point. Just the main code block already tells almost the whole story:
This came out of playing around with curl and the Lemmy API. I wanted a repeatable way to declare a bunch of shell parameters from a json object, so I wrote a jq module! Take a look at the README for examples, or once you install, run
Ever since I started down the self-hosting rabbit hole one issue I've been constantly annoyed with is transferring files between machines. Especially files which I am currently working on and that I want to periodically transfer to a specific remote location.
For fun, convenience and a chance to learn shell scripting for myself, I've been working on a collection of scripts to semi-automate the backup of my computer, two network connected Raspberry Pi's and my Android phone with Termux.
After a long time I'm in a situation where I sometimes work on a temporary system without my individual setup. Now whenever I might add a new custom (nushell) command that abstracts the usage of CLI tools, I think about the loss of muscle memory/knowledge for these tools and how much time I waste looking them up without my individual setup. No, that's not a huge amount of time, but just out of curiosity I'd like to know how I can minimize this problem as much as possible.
The document itself is paywalled like all the POSIX specifications, so here are some highlights courtesy of some comments at HackerNews, especially from a-french-anon.
At the moment, I am stuck with using single-precision float, and double-precision float. So, the maximum represent-able value for single is 1<<24 while for double, it is 1<<53.
This release of fish includes a number of improvements over fish 3.6.4, detailed below. Although work continues on the porting of fish internals to the Rust programming language, that work is not included in this release. fish 3.7.0 and any future releases in the 3.7 series remain C++ programs.
I'm sure some of you have absolute monstrosities of sigils (I know I do, in my .zshrc alone). Post them without context, and try and guess what other users's lines are. If you want to provide context or guess, use the markdown editor to spoiler-tag your guesses and explanations!
