Options which can be used with Deno.run.

Properties

cmd: readonly string[] | [string | URL, ...string[]]

Arguments to pass.

Note: the first element needs to be a path to the executable that is being run.

optional
cwd: string

The current working directory that should be used when running the sub-process.

optional
env: Record<string, string>

Any environment variables to be set when running the sub-process.

optional
stdout:
| "inherit"
| "piped"
| "null"
| number

By default subprocess inherits stdout of parent process. To change this this option can be set to a resource ID (rid) of an open file, "inherit", "piped", or "null":

  • number: the resource ID of an open file/resource. This allows you to write to a file.
  • "inherit": The default if unspecified. The subprocess inherits from the parent.
  • "piped": A new pipe should be arranged to connect the parent and child sub-process.
  • "null": This stream will be ignored. This is the equivalent of attaching the stream to /dev/null.
optional
stderr:
| "inherit"
| "piped"
| "null"
| number

By default subprocess inherits stderr of parent process. To change this this option can be set to a resource ID (rid) of an open file, "inherit", "piped", or "null":
