How to get args passed after the script?

[hustcer]

If I ran try.sh foo in the console, I can get the foo input by $1.
And How to get args passed after the nu script?

nu try.nu foo bar

How can I get the param foo and bar ? Thanks.

Hey! It depends on what try.nu is doing.

The common scenario is probably defining a command in a Nu script, like this:

# try.nu

def say-hello [name] {
    echo $"Hello, ($name)!"
}

You can have multiple command arguments in the square brackets.

In order to use say-hello, you have to source try.nu and then the command will be available in the shell:

$ source try.nu
$ say-hello hustcer
Hello, hustcer!

If try.nu is a list of commands you want to run, I'm not sure how you could directly pass parameters from the command line.

Can you use a command definition like this for your use case and does this answer your question?

currently, i don't believe nushell supports passing multiple arguments on the nushell command line to scripts. i.e. nu some_script.nu param1 param2 param3 however, we do support custom commands, like @filaretov points out, and they can support multiple arguments. I'm closing with these answers. if we're missing what you're saying, please re-open.

@fdncred @filaretov Thanks for your reply, source the script before run may help sometimes, but that's not enough: I wish I could run my scripts without sourcing, because the script may be called by npm run in a package.json file.
Maybe this reply express what I want.
