`nevia exec [FLAGS] [COMPUTER] [-- CMD]…`

Exits with the command's exit status. With no command, opens a shell.

Piped stdin is sent once it closes, up to 1 MiB; use -n when it never closes. The computer must be running: exec never wakes it and exits 5, so run `nevia awake` first.

### Arguments

* `[COMPUTER]` - Computer ID or name (optional when the workspace has one computer)
* `[-- CMD]…` - Command and arguments after -- (default: the computer's shell)

### Options

* `-i, --interactive` - Stream this terminal's stdin to the command

* `-n, --no-stdin` - Send no stdin, even when it is piped
