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.

run(cmd, opts)

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

Start a new command.

Parameters

Parameter	Type	Description
cmd	string	command to execute.
opts?	CommandStartOpts & object	options for starting the command. - opts.background: true - runs in background, returns CommandHandle - `opts.background: false	undefined- waits for completion, returnsCommandResult`

Returns

Promise<CommandResult | CommandHandle>

Either a CommandHandle or a CommandResult (depending on opts.background).

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>
