I want to access all the arguments and run the same command on each argument in the list.
#!/usr/bin/env nu
def main [ one, two ] {
// echo each item in the argument list
}
How to achieve this in nushell?
CodePudding user response:
It sounds like you are looking for Rest parameters:
def main [...args: string] {
$args| each { echo $in }
}
> main one two three
╭───┬───────╮
│ 0 │ one │
│ 1 │ two │
│ 2 │ three │
╰───┴───────╯
args
can be named whatever you want. The only "magic" variable in that example is $in
, which could be replaced with the non-magic form:
$args| each { |item| echo $item }
