I’ve been trying nushell and words fail me. It’s like it was made for actual humans to use! 🤯 🤯 🤯

It even repeats the column headers at the end of the table if the output takes more than your screen…

Trying to think of how to do the same thing with awk/grep/sort/whatever is giving me a headache. Actually just thinking about awk is giving me a headache. I think I might be allergic.

I’m really curious, what’s your favorite shell? Have you tried other shells than your distro’s default one? Are you an awk wizard or do you run away very fast whenever it’s mentioned?

    I used nushell for a good 6 months, it was nice having structured data, but the syntax difference to bash which I use for my day job was just too jarring to stick with.

    Fish was (for me) the right balance of nice syntactic sugar and being able to reasonably expect a bash idiom will work.

        What awful syntax?

        Ffs bash uses echo "${filename%.*}" and substring=${string:0:5} and lower="${var,,}" and title="${var^}" &c. It doesn’t use $ for assignment, only in expressions.

    I love Nushell, it’s so much more pleasant for writing scripts IMO. I know some people say they’d just use Python if they need more than what a POSIX shell offers, but I think Nushell is a perfect option in between.

    With a Nushell scripts you get types, structured data, and useful commands for working with them, while still being able to easily execute and pipe external commands. I’ve only ever had two very minor gripes with Nushell, the inability to detach a process, and the lack of a -l flag for cp. Now that uutils supports the -l flag, Nushell support is a WIP, and I realized systemd-run is a better option than just detaching processes when SSHd into a server.

    I know another criticism is that it doesn’t work well with external cli tools, but I’ve honestly never had an issue with any. A ton of CLI tools support JSON output, which can be piped into from json to make working with it in Nushell very easy. Simpler tools often just output a basic table, which can be piped into detect columns to automatically turn it into a Nushell table. Sometimes strange formatting will make this a little weird, but fixing that formatting with some string manipulation (which Nushell also makes very easy) is usually still easier than trying to parse it in Bash.

    I’m really curious, what’s your favorite shell?

    Emacs eshell+eat

    It essentially reverses the terminal/shell relationship. Here, it’s the shell that starts a terminal session for every command. Eshell is also tightly integrated with Emacs and has access to all the extended functionality. You can use Lisp in one-liners, you can pipe output directly to an emacs buffer, you can write custom commands as lisp functions, full shortcut customization not limited to terminal keys, history search via the completion framework (i.e. consult-history), easy prompt customization, etc.

    There’s also Tramp, which lets you transparently cd into remote hosts via ssh, docker containers, SMB/NFS-shares, archive files, and work with them as if they were normal directories (obviously with limited functionality in some cases, like archives).

    And probably a lot of stuff I’m missing right now.

    I like nushell, but I love xonsh. Xonsh is the bastard love child of Python and Bash.

    it can be thought of as:

    • try this statement in Python
    • if there’s an exception, try it in bash.

    Now, that’s not a very accurate description, because the reality is more nuanced, but it allows for things like:

    for file in !(find | grep -i '[.]mp3^'):
        file = Path(file.strip())
        if file != Path('.') and file != file.with_suffix('.mp3'):
        mv @(file) @(file.with_suffix('.mp3'))
    

    Now, there are things in there I wouldn’t bother with normally - like, rather than using mv, I’d just use file.rename(), but the snippet shows a couple of the tools for interaction between xonsh and sh.

    • !(foo) - if writing python, execute foo, and return lines
    • @(foo) - if writing sh, substitute with the value of the foo variable.

    But, either a line is treated in a pyhony way, or in a shelly way - and if a line is shelly, you can reference Python variables or expressions via @(), and if it’s Pythony, you can execute shell code with !() or $(), returning the lines or the exact value, respectively.

    Granted, I love python and like shell well enough, and chimeras are my jam, so go figure.

        It’s a superset of python, so valid python should run fine. Imports into your shell are doable, too – for example, I import path.Path in my xonshrc, so it’s always available when I hit the shell. I don’t often have to use Path, because regular shell commands are often more straightforward. But when I do, it’s nice to have it already loaded. Granted, that could get kooky, depending on what you import and execute.

        You can associate/shebang Xonsh with .xsh files, or run “xonsh foo.xsh” - and that works like “bash foo.sh” would, except using xonsh syntax, of course.

        It’s not Bash compatible - copypasta of scripts may not work out. But it’s a good shell with some typical shell semantics.

        there are some great plugins, too - like autovox, which allows you to create python venvs associated with specific subfolders. so, cd myproject does the equivalent of cd myproject; . path/to/venv/bin/activate.

        overall, there definitely is some jank, but it’s a great tool and I love it.

          Hm. That sounds delightful. I do think once your script hits a not one liner level of complexity, python is a logical next step.

          Does it provide any useful stuff to Python itself? Would I like, derive any benefit to writing a script in xonsh over pure python?

            Succinctness, mainly. but honestly, that succinctness call can also be mostly acquired using sh.py, which is what I normally use if I’m using python as a sort of shell scripting - mostly because sh.py is a very minimal requirement, whereas Xonsh has quite a few dependencies.

            addendum: I’d say, if you’re already using Xonsh, and aren’t really looking to share your script with anyone other than Xonsh users or your own systems, you’d probably like to use .xsh scripts. But if you’re looking to share your script, use sh.py.

      Xonsh is also a really cool option. If I used Python more regularly and was more comfortable using it without having to look stuff up, I’d probably use it over Nushell.

    I feel like if I was forced to use PowerShell I’d fall in love with it and want to use it on Linux. Passing objects between commands instead of text sounds amazing. So many (Linux) shell commands use slightly differently shaped text, it’s annoying. New line separated? Tab separated? Null separated? Comma separated? Multiple fields? JSON? And converting between them all and using different flags to accept different ones is just such a headache.

      PowerShell’s import-csv and export-csv are too dang powerful. Doing batch processing in PS is so cool.

        It is, but I know myself and realistically unless I’m forced to learn it in an environment where it’s first class I’m not going to use it on a regular basis.

    I’ve used nushell for several months, and it really is an amazing shell

    It feels more like an actual language than arcane runes, and I can easily makes chains and pipelines and things that would be difficult in bash

    Additionally, it makes a pretty good scripting language

    Formatting doesn’t like my input for some reason so I am just going to shorten it to ls -ltc | grep '>'.
