Struct Command

pub struct Command {
    pub exe: Exe,
    pub wd: Option<Directory>,
    pub argv: Argv,
    pub env: EnvModifications,
}

<exe={exe}, wd={wd:?}, argv={argv}, env={env}>

Request to execute a subprocess. See crate::sync and crate::stream for examples of invocation.

Fields

exe: Exe

argv: Argv

Arguments to pass to the executable. These should not be quoted at all.

env: EnvModifications

Any new environment variables to set within the child process. The environment is otherwise inherited from the parent.
