Promise<CommandHandle> CommandHandle handle to interact with the running command.

kill()

kill(pid: number, opts?: CommandRequestOpts): Promise<boolean>

Kill a running command specified by its process ID. It uses SIGKILL signal to kill the command.

Parameters

`pid`	`number`	process ID of the command. You can get the list of running commands using Commands.list.
`opts`?	`CommandRequestOpts`	connection options.

Returns

Promise<boolean> true if the command was killed, false if the command was not found.

list()

list(opts?: CommandRequestOpts): Promise<ProcessInfo[]>

List all running commands and PTY sessions.

Parameters

Parameter	Type	Description
`opts`?	`CommandRequestOpts`	connection options.

Returns

Promise<ProcessInfo[]> list of running commands and PTY sessions.

run()

run(cmd, opts)

run(cmd: string, opts?: CommandStartOpts & object): Promise<CommandResult>

Start a new command and wait until it finishes executing.

Parameters

Parameter	Type	Description
`cmd`	`string`	command to execute.
`opts`?	`CommandStartOpts` & `object`	options for starting the command.

Returns

Promise<CommandResult> CommandResult result of the command execution.

run(cmd, opts)

run(cmd: string, opts?: CommandStartOpts & object): Promise<CommandHandle>

Start a new command in the background. You can use CommandHandle.wait to wait for the command to finish and get its result.

Parameters

Parameter	Type	Description
`cmd`	`string`	command to execute.
`opts`?	`CommandStartOpts` & `object`	options for starting the command

Returns

Promise<CommandHandle> CommandHandle handle to interact with the running command.

sendStdin()

sendStdin(
   pid: number, 
   data: string, 
opts?: CommandRequestOpts): Promise<void>

Send data to command stdin.

Parameters

Parameter	Type	Description
`pid`	`number`	process ID of the command. You can get the list of running commands using Commands.list.
`data`	`string`	data to send to the command.
`opts`?	`CommandRequestOpts`	connection options.

Returns

Promise<void>

Pty

Module for interacting with PTYs (pseudo-terminals) in the sandbox.

new Pty(transport: Transport, connectionConfig: ConnectionConfig): Pty

Parameters

Parameter	Type
`transport`	`Transport`
`connectionConfig`	`ConnectionConfig`

Returns

Methods

create()

create(opts: PtyCreateOpts): Promise<CommandHandle>

Create a new PTY (pseudo-terminal).

Parameters

Parameter	Type	Description

Returns

Promise<CommandHandle> handle to interact with the PTY.

kill()

kill(pid: number, opts?: Pick<ConnectionOpts, "requestTimeoutMs">): Promise<boolean>

Kill a running PTY specified by process ID. It uses SIGKILL signal to kill the PTY.

Parameters

Parameter	Type	Description

`opts`?	`Pick`<`ConnectionOpts`, `"requestTimeoutMs"`>	connection options.

Returns

Promise<boolean> true if the PTY was killed, false if the PTY was not found.

resize()

resize(
   pid: number, 
   size: object, 
opts?: Pick<ConnectionOpts, "requestTimeoutMs">): Promise<void>

Resize PTY. Call this when the terminal window is resized and the number of columns and rows has changed.

Parameters

Parameter	Type	Description
`pid`	`number`	process ID of the PTY.
`size`	`object`	new size of the PTY.
`size.cols`	`number`	-
`size.rows`?	`number`	-
`opts`?	`Pick`<`ConnectionOpts`, `"requestTimeoutMs"`>	connection options.

Returns

Promise<void>

sendInput()

sendInput(
   pid: number, 
   data: Uint8Array, 
opts?: Pick<ConnectionOpts, "requestTimeoutMs">): Promise<void>

Send input to a PTY.

Parameters

Parameter	Type	Description
`pid`	`number`	process ID of the PTY.
`data`	`Uint8Array`	input data to send to the PTY.
`opts`?	`Pick`<`ConnectionOpts`, `"requestTimeoutMs"`>	connection options.

Returns

Promise<void>
