Excellent Utilities: exa – replacement for ls

Last Updated on May 22, 2022

In Operation

Here’s the output generated running exa with the long view, showing the files, metadata, including permission bits, file sizes, and timestamps.


You’ll notice the software offers an attractive color scheme, helpfully making sense of the information you’re presented with. The screen image only shows some of the goodness available. For example, it doesn’t show that exa highlights different file types such as image files, video files, documents, music, archives, cryptography, and much more.

exa lists file sizes using decimal prefixes by default: bytes, kilobytes, megabytes, gigabytes, and so on. Having human readable sizes by default is one of the many differences between exa and ls. The only (initial) downsize is that you need to inspect the suffix to interpret the file size.

One of the tool’s strengths is its long grid view making optimum full use of your monitor. The software displays as many columns as possible with full permissions information.

As an aside, you’ll notice the README and README.md files are coloured differently. These are known as ‘immediate’ files. ‘Immediate’ files are files that are useful files to read or run first. Think of them as your starting point.

You can have directories displayed first with the long ISO time style with the command:

$ exa -l –time-style=long-iso –group-directories-first

There’s also a useful tree view available which is analogous to the tree command. The tree displays sub-directories inside the listing of their parent directories, helping visualize the directory structure and see which files are where.

I cringe when I read about CLI utilities written in Rust. That exa binary is over 800KB! (see the exa debian amd64 package)

You make it sound like you’ve made a discovery. Next you’ll be telling us Firefox is a memory hog.

And you should remember that “software bloat always expands to make use of all the memory available” ;+}

It is not a discovery for me, but will be for some, as there are deliberate attempts to cover up how bloated rust-created binaries are. For example, the description here packages.debian.org/sid/exa: “and it is small, fast, and one single binary”. of course, “small” is relative. ‘ls’ is about 145KB. Does some colour-coding, extra columns and git compatibility justify the extra 600KB? I am old-school, probably these days the younger generation of programmers don’t care about the bloat, just the coding conveniences — I have to have a bit of a grumble about it though.

You have to take into consideration that the average amount of disk space on any given computer is growing. In the grand scheme of things, on most computers that have a 200GB or so hard drive inside, a 600KB binary is incredibly small. It’s all relative. Of course, if you’re speaking in terms of an old laptop without much disk space, that’s probably not the best use case for exa anyway. Also, I don’t think anyone is denying that rust binaries are larger than normal. It’s a fact, considering that the entire rust standard library gets compiled in. One man’s bloat is another man’s minimalism.
