echo for core

Returns its arguments, ignoring the piped-in value.

Signature

> echo ...rest

Parameters

• ...rest: the values to echo

Notes

When given no arguments, it returns an empty string. When given one argument, it returns it. Otherwise, it returns a list of the arguments. There is usually little reason to use this over just writing the values as-is.

Examples

Put a list of numbers in the pipeline. This is the same as [1 2 3].

> echo 1 2 3
╭───┬───╮
│ 0 │ 1 │
│ 1 │ 2 │
│ 2 │ 3 │
╰───┴───╯

Returns the piped-in value, by using the special $in variable to obtain it.

> echo $in
