【1:29】 Useful Unix Utilities

■ ▲ ▼

1 Name: Nameless : 2026/01/14 21:27

What are some useful Unix utilities you've been using lately?

Something that's entered my toolbox in the last few months is `just`.
https://github.com/casey/just

They're kind of like Makefiles but simpler, because it's not trying to be a build utility. It just runs commands. After a few months of use, I have justfiles sprinkled all through my system to run various project-specific shell commands. It hits a sweet spot between one liners and dedicated scripts, and it has really enhanced various workflows for me. Things that I wouldn't have automated before (because it feels too small), I *do* automate now, because these justfiles feel like an appropriate place for those little tasks.

Tar zxf is convenient compared to cpio, the true UNIX archiver. While cpio -i extracts the files from an archive like you would expect, cpio -o is very different from most other archive programs, expecting to read a list of files from standard input. Replicating the behavior of '7z a archive directory' requires something like 'find directory | cpio -o (| gzip > archive)'.

Too bad cpio hasn't been standardized since System V Release 4 or i would send it more often to people.

How do you feel about pax?

NotThatNameless, but it lacks encryption.

29 Name: Nameless : 2026/07/04 09:42

>>27
I don't use it, because it's rarely part of the base system and i always type tar out of habit. Iterating on the ar/tar syntax and badgering everyone to link tar to their new and slightly incompatible ar!pax program would have been the smarter choice honestly, which is sort of what libarchive did with "bsdtar". The pax format seems fine, but i have no idea what the benefit over ustar is.
>>28
As it should, since you ought to encrypt on the file level at least.

【4:13】 Resolution

■ ▲ ▼

1 Name: Nameless : 2026/05/04 23:52

What is your current screen resolution?
Mine is 1024x768, I've used larger displays in past but I've noticed that most of that space is usually empty and I prefer information density. 1024x768 was also the standard when most of the software I use was made, so things tend to fit neatly.

9 Name: Nameless : 2026/05/08 22:09

30hz is the lowest you'd need, and honestly it would be quite comfortable, but I think 60-100~hz is about perfect.

10 Name: Nameless : 2026/05/08 23:55

ideally, I would have some kind of crazy 600hz screen, but I play rhythm games and thus actually do need the extra framerate so notes don't just jump down the screen in big, hard to read steps when I increase my scroll speed

11 Name: Nameless : 2026/05/12 12:54

when my trinitron was still working i used 1280x960@90Hz, then the green gun gave up the ghost, and now i'm stuck with a 1024x768 LCD and i absolutely hate it, because i don't know how to fix the trinitron. 16:9 just feels wrong to me now.

12 Name: Nameless : 2026/05/12 17:24

>>11
16:9 is cool for watching stuff and work but 4:3 is perfect for everything else
The web alone has never looked good on a 16:9 screen
To the point where modern websites are either zoomed in (which looks terrible) or have borders.
For games, it depends. I'd say only FPS are worth playing on a 16:9 screen (except maybe the older ones like Doom ).

13 Name: Nameless : 2026/05/13 16:53

>>12
I miss my 1280x1024 screen because web browsing really does suck at 1920x1080.

Nano rocks. When I'm writing a program in C++ I have two terminal windows open on the left/right side of my screen. On one I have nano open and the other I use to run cmake/make. Honestly the best dev setup I've come up with since I started programming

I am the bone of my SICP.

So, what OS do you use? Do not reply if you use Windows, unless it's pre-xp.

46 Name: Nameless : 2026/04/13 17:48

as much as Sun was a good company (as far as corporations go) before they got bought out, it is good that we have left Solaris behind

maybe not entirely good (Solaris binary compatibility certainly is a lot nicer than Linux's, regardless of the Linux kernel's don't break userspace ideal)
but for all of the good design choices Sun made, they made a lot of bad ones, choices that Linux avoided

47 Name: Nameless : 2026/04/14 05:14

>>46
Solaris did a lot of things right, that Linux still struggles to replicate.

Mdb and dtrace remain unmatched as of 2026. eBPF development means it's likely dtrace may be implemented on top some time in the future, yet gdb, lldb and whatnot will likely stay subpar, let alone every distro i know stripping binaries by default.

ZFS integration into the kernel means read caching ("ARC") is more efficient and responsive. The entire boot environment/ZFS stack is a treat, compared to fstab and the occasional Linux bootloader woes.

I'm partial towards static device management, but the /devices - /dev split is certainly a lot nicer than what ended up as udev. All hardware devices in /dev are symlinks to /devices (a kernel "devfs"), which also contains things you might find in /sys on Linux. In addition to pci-utils it also has its own tools, that uniformly handle hotplugging and such for any device type.

I would also rank SMF above systemd, if i was pressed, since it centralizes configuration and editing XML with the provided tools is tolerable. The fact it's a coherently designed system makes administration more intuitive in general, despite some of the iffy parts.

I think it's really lazy and am against it since it really messes things up in ways you don't want it. The only way to make what is projected in your head is to do it yourself, a robot will never understand what you mean exactly.

What I really don't like is how it just makes shit up sometimes. It sounds plausible too. It is the ultimate bullshitter.

If it can't find you an answer, it will just make up one instead of telling you it failed.

ima linux user and ive been recently thinking about instaling unix on a vm to try it
how does it compare to gnu/linux?
i know linux was based on how unix works so i expect some similarities but i also know that its propably another thing to learn from scratch
any advice?

You would say wrong

18 Name: Nameless : 2026/05/17 17:34

There's no reason to have it unless you are overly cautious about getting randomly hacked, it's pretty overkill in that sense. You would be better off running a openbsd router and then running freebsd as a desktop for usability with the same security benefits.

>There's no reason to have it unless you are overly cautious about getting randomly hacked, it's pretty overkill in that sense.
This is a common misconception. Most people use it for the sane code practices, the manuals and the ease of use, which are things that just happen to be in common with good security. Sun also made the most secure machines on the market at the time because they thought it was a requisite, but the clients weren't looking exclusively for that.
He asked for a good unix system and i recommended one with good documentation and no ambiguity which is essential to someone that wants to learn about how things actually work.
>Running freebsd as a desktop for usability with the same security benefits.
Are you serious? Did they stop making OS and software vulnerabilities? Now they only target routers? I didn't know that.

20 Name: Nameless : 2026/05/17 19:29

>Now they only target routers? I didn't know that.
It's harder for anything to get hacked on a network since everything has to go through the router. In any way, I still recommend freebsd but it's whatever.
