Rust Programs Every Linux User Should Know About

It seems like every new program is written in Rust these days. In fact, many older programs are being rewritten in Rust, including a lot of the standard shell utilities. Today, I wanted to briefly mention seven Rust programs that I have installed that I think you should know about.

The biggest reason for ripgrip (rg) wasn't mentioned: speed. When it comes to recursive searches, rg absolutely destroys stock grep. It's way, way faster. It's also clever: that pretty output that it does to make it more human readable only occurs when it knows the output is the terminal. If you pipe the rg results to anything else, it knows that and switches to the more typical line-by-line response.

[@wildflowers465]

Same goes for bat when piping it to another program

Bat really isnt a cat replacement it's more of a less/more replacement

[@DistroTube]

True.

[@aedd3307]

not true though, bat justs highlights syntax and adds line numbers, then sends its output to less

[@hostgrady]

@@aedd3307 ok. But in practice the experience is the less command. So in reality it replaces less more than cat (at least by default idk if theres any flags)

[@CMG78]

can do the same with cat -n .zshrc | less

[@onehaxxor8574]

@@aedd3307 and that's exactly what a 'cat' replacement must not do. 'cat' comes from 'conCATenate'. The intended usage of 'cat' is to concatenate multiple files, as in '$ cat file1.txt file2.txt >> file1-2.txt'. Thus 'cat' must not mess with the input stream unless you explicitly tell it to do so. If you replace standard gnu utils the system relies on with tools behaving differently (like eg 'alias cat='bat') things will break.

I am a Sr Software Engineer who does know Rust. Rust is a "immutability first" language. Often times the reasons vulnerabilities in code occur is due almost exclusively to mutable data in memory that's getting modified in real-time by other software trying to take advantage of the memory exploits. Rust makes mitigating this a first-class citizen. Which means, if immutability principles are followed, the amount of vulnerabilities will naturally fewer and, when they do occur, much less likely to have downstream effects, while being more easily maintained. Rust as an amazing system-level language. It is a C-level language. Other languages based on Rust are coming down the line at some point. NodeJS linked-libraries are being written in Rust as well as Web Asslembly. Web Assembly is a compile target of Rust for web applications. Rust has a TON to offer the software community.

[@notuxnobux]

immutable variables in rust only guarantee compile-time immutability. They can be modified if the program is hacked. On linux you need to mmap a memory region and use mprotect to prevent the data from being modified at runtime.

[@apestogetherstrong341]

hey mr. Sr Software Engineer, could you explain how local variables in a function which are on the stack are immutable at the binary level?

[@ssokolow]

@@apestogetherstrong341 I get what you meant but that *can* actually happen in both Rust, C, and other languages. It's called "const promotion". Basically, when the compiler recognizes that it's safe to perform the calculation at compile time and store the result in the compiled binary as an optimization even though you didn't use explicitly use `const`. That said, Rust *does* help to give the compiler backend more freedom to do stuff like that by making stronger promises about how things will behave. (And, as such, it'd also be more amenable than C or C++ to automatic insertion of calls like mprotect.)

[@apestogetherstrong341]

@@ssokolow well, const promotion can't happen with something like "let x = arg_1 + 2", in that case it's just incrementing the stack pointer and moving to it. But yeah, i get what you meant too

I ve got an off topic question, as you are using the ergodox. There is something like the zsa moonlander have you ever heard of it if yes is it likely that you would give it a try if the one you currently got for example broke? Unfortunately there aren't many user videos and like reviews so that there would be more than just first impressions...

[@edakimling133]

There are quite a decent number of reviews now. One guy even specializes in it. Just search for ergodox vs moonlander. A british guy did a fantastic review of both. There are some major differences, and I mean really significant to consider. I would tend to say moonlander si better, but ergodox also has ome points going for it. It depends what you want. I ordered my moonlander a week ago. Still 1 month to go till I receive it. Major differences I found: moonlander is more compact; better for travel. The thumb area swivels, this is more ergonomic and also allows for adjustment for smaller/bigger hands. Thumb area has better key redesign. Moonlander has RGB on every single key; not so on ergodox. Lot of keys do not have RGB. RGB is thicker, more robust and also since thumb area does not pivot, it has 1 less point of breakage in the hinges. In fact the reviewer in the youtube video I mentioned - his hinge on the thumb pad broke. Could have been a defect though. Moonlander uses type c cable (not that big deal though). Exterior row on each side has keys that are less wide on the moonlander, bringing the center point where you press closer to your finger, which could be important. These are some major highlights. Cost is the same. It was here, on DT video I learned of the ergodox and subsequently bought the moonlander! Super excited.

Go and Rust are popular modern systems programming languages for a reason. Built in build systems, package management, and testing suites lead to building robust fast reliable software very quickly. Just look at how fast the Pop!Os team can pump out really good systems level software with some of the best runtime safety in the game. Go routines provide a revolutionary way to implement concurrency. So many benefits behind these languages. They also lack all the "history" and backwards compatibility bloat issues that languages like C++ have. Referring to these languages as "memes" merely shows a drastic misunderstanding of what they accomplish.

[@Dee-Ell]

Often, it's preferable to stick with commands that are standard/default to most machines.

So while all these tools are cool, it's not cool enough for me to invest on them and abandon the more widely available standard commands.

[@dapodix]

I tend to agree with sticking with the POSIX standard tools but would point out that these rust tools are statically compiled binaries that you can copy around via scp/ssh and run them arbitrarily without even needing to install them into a standard $PATH. Cant imagine doing this for a prog written in python or node/typescript however.

[@onehaxxor8574]

Ignoring the discussion c/c++ vs rust, the problem I have with these rewrites is that they often change the default behavior and interface. There most probably is a reason why tools behave the way they do, even if you as a user don't understand or know it. cat, ls, find, ... are all POSIX standard utilities the system and a lot of software relies on that you simply cannot mess with. You want to reimplement gnu or standard utils? Fine, but retain default behavior and the interface. Otherwise, do not advertise them as replacements, bc they are not. They are alternatives, but not replacements.

[@onehaxxor8574]

@@bigpod replacements have exactly the same behavior and are completely interchangeable. Not the case with most of these rewrites. It's like changing APIs or interfaces. If they do not behave exactly the same, they are not interchangeable and thus not replacements. Also you should care about standards like POSIX because they guarantee interoperability and portability. But then again, if people do not understand the crucial importance of stable APIs and interfaces, and why there have to be reliant contracts for IPC, then they shouldn't program essential tools or services in the first place. Changing well-known, reliant and expected behavior, just for the sake of being different and promoting one self's ego (I know better, I do it my way), will break systems and make maintaining interoperability between processes a nightmare.

@@bigpod try the following then: $ sudo cp -f ~/.cargo/bin/bat $(command -v cat) $ sudo mkinitcpio # on arch, or update-initramfs on debian, check your distro $ sudo reboot With my understanding of replacement, this should work flawlessly, but then again, my understanding could quite possibly be flawed. Chances are, your system won't even boot anymore, because 'cat' is an essential binary used in the initial ramdisk to boot practically all unixoid OSes, which is possible thanks to standardization like POSIX. But since you do not care about standards, interoperability and portability, having to repair constantly breaking and non-functioning systems is probably not a problem for you anyways.

Rust language would be my top choice for a programming language to be stranded on a desert island with a laptop and solar powered battery recharger - if could have only one language choice. It's intrinsically versatile enough to be applied to about any programming domain - with Web Assembly support, could even be used to write programs that run in the browser. And presumably being stranded on said island, would have plenty of time to master its borrow checker and annotations - and the cool kids stuff like pattern matching and other functional programming features. And finally get around to learning how to write macros in its powerful macro sub-language.

the difference is that C is a programming language with the most basic features from the 1960s these features allow you describe low level stuff C is basically a template language for good programming patterns in ASM but this comes without safety and is prone to produce all sorts of damage like segfaults Rust is a programming language with sophisticated features from different languages including Programming Language Theory (research) including the experience of the last 30 years in the industry and lessons learned in C++ also allows you to describe low level stuff its memory model protects you from segfaults without producing any runtime dependency (due to that ivory tower research that hackers tend to despise) basically C is garage amateur carpentry while Rust is space tech engineering.

bat uses your $PAGER (less by default) to display its contents when in an interactive shell. This can be bypassed with the -P option, or configured to use a different one, or none.

I haven't programmed anything serious on Rust, but as far as I have seen about the language, it seems to be a modern and better version of C++, I have programmed on C++ since before C++11 was a thing and by today's standard C++ has became a very bizarre language. For example on C++ is a best practice to mark every variable as «const» or «constexpr» unless you need it to change while on Rust variables are «const» by default and you only need to mark them as «mut» when you need it. Some people have said that “Rust is not as efficient as C++” by comparing the ASM output of same codes, but that is not true, the compiler might not be as efficient, but IMHO the language is as efficient as C++.

Assuming you aren't trolling here there's a clear difference between Rust, a programming language and Firefox, Thunderbird, etc which are internet programs. Rust is a programming language, it is harder to censor and almost conpletely pointless to do so anyways because of the abundance of other programming languages which aren't censored. Mozilla's other software like their browser and their email client are much easier to censor and there is a motivation to do so.

Sorry, but judging by the output of bat, it's not a replacement of cat, but for something like less or more. Because when using cat, you only expect the file content to show up on stdout. That's necessary for piping as well.

[@koderkev42]

This is my thought as well. Bat is nice but not a replacement for sure.

@@koderkev42 bat checks for the output method first, that formatting only happens in terminal, not piping; read the man.

[@Asdayasman]

> I don't see why anyone wouldn't just replace `cat` Because it works just fine, and you really shouldn't be using it for reading files at the terminal (use `less`). Rust's advantage over C is its memory safety. `cat` is already memory safe. Thus as a user, there is no advantage to me switching.

[@stephen9849]

The linux kernel and most of the linux programs used to be written in C which is a very old language and even for those with experience it can be hard to write code in C, rust is a new programming language which can replace C because it's also low level, so it's very fast (not faster than C but close) and it has some features that make it easier to code in.

[@lieywe3438]

Recent benchmarks have shown that Rust can be faster than C. However, I don't think of Rust as a C replacement but an addition to systems programming. There will always be scenarios where it'll be preferable to use C/C++ in systems programming. Rust allows you to write low level code in a precise, short and abstract way - that is brilliant. But it also has very strict rules and sometimes doesn't let you do "your way of programming". Nevertheless, I do most of my programming in Rust. I just don't think of it as a replacement

[@brinckau]

@@lieywe3438 How can it be faster than C? Is it a compiler issue (poor optimisations by C compilers), or is it the langage itself? It seems to me that C is closer to machine code than Rust. So I don't get how Rust could be faster.

[@ekremdincel1505]

@@brinckau Rust, as a abstract language, has more optimization opportunities than C, the abstract language. It is about language semantics. And C is not more close to the hardware than Rust, they are same.

[@brinckau]

@@ekremdincel1505 Assembly is not an abstract language, is converted to machine code without any optimization, and yet cannot be beaten in terms of speed (because in the end, everything is machine code, so writing machine code directly, or assembly code, makes it possible to do exactly the same as a C or Rust program would do). Provided you're good enough to write excellent code, of course. So I'm not convinced by your argument about optimization opportunities. I also believe that C is closer to machine code than Rust, because Rust has more abstractions than C. Otherwise, Rust would not have more optimization opportunities than C.

[@ekremdincel1505]

@@brinckau Every language is abstract. I mean the formal definition of the language regardless of current implementations. I didn't even say anything about assembly in my previous post. You can write inline assembly in Rust. Rust's abstractions are zero cost. And having useful abstractions not necessarily prevents you from having tools for writing low level code in your language. Rust have both safe references and unsafe raw pointers, for example. "So I'm not convinced by your argument about optimization opportunities." An example about language semantics: Rust inserts C's equivalent of "restrict" keyword everywhere, thanks to it's borrow checker, and this gives the more optimization opportunities. People use the "restrict" keyword in C so rarely. Not everything is theoretical.

Hi mate. time stampts might be useful in this video :)

[@matthewstott3493]

Rust is basically C++ with an extremely strict compiler with far improved error messaging for developers. Rust is focused on avoiding bad security practices. You cannot compile code that has glaring security problems. It will stop and force you to fix your code and it Is pretty good about giving you a meaningful error message for the compile failure. Rust is far more opinionated and security focused than C++ which allows a developer to do whatever they want without much complaint, providing it compiles. Rust will stop someone from compiling bad code. Rust won't remove all security issues but it covers the big ones that are most common among most security exploits. This is why there is so much talk about using Rust for systems programming such as an OS kernel. Linux is looking to allow device drivers to be written in Rust. But that isn't the only reason to choose Rust for any development project. It's a very nice language and that compiler still gives you much better feedback when a compile fails. Lots of people have been dipping their toes into Rust and that is why there are so many nifty Rust programs. Rust programs can be highly performant.
