default 'json'

Optional Readonly shell

• shell? : boolean | string

Inherited from ExecuteOptions.shell

Defined in node_modules/execa/index.d.ts:178

If true, runs command inside of a shell. Uses /bin/sh on UNIX and cmd.exe on Windows. A different shell can be specified as a string. The shell should understand the -c switch on UNIX or /d /s /c on Windows.

We recommend against using this option since it is:

• not cross-platform, encouraging shell-specific syntax.
• slower, because of the additional shell interpretation.
• unsafe, potentially allowing command injection.

default false

Optional Readonly stderr

• stderr? : StdioOption

Inherited from ExecuteOptions.stderr

Defined in node_modules/execa/index.d.ts:82

Same options as stdio.

default 'pipe'

Optional Readonly stdin

• stdin? : StdioOption

Inherited from ExecuteOptions.stdin

Defined in node_modules/execa/index.d.ts:68

Same options as stdio.

default 'pipe'

Optional stdio

• stdio? : StdioOption

Overrides void

Defined in src/util/types.ts:66

The options.stdio option is used to configure the pipes that are established between the parent and child process.

Optional Readonly stdout

• stdout? : StdioOption

Inherited from ExecuteOptions.stdout

Defined in node_modules/execa/index.d.ts:75

Same options as stdio.

default 'pipe'

Optional Readonly stripFinalNewline

• stripFinalNewline? : undefined | false | true

Inherited from ExecuteOptions.stripFinalNewline

Defined in node_modules/execa/index.d.ts:103

Strip the final newline character from the output.

default true

Optional Readonly timeout

• timeout? : undefined | number

Inherited from ExecuteOptions.timeout

Defined in node_modules/execa/index.d.ts:192

If timeout is greater than 0, the parent will send the signal identified by the killSignal property (the default is SIGTERM) if the child runs longer than timeout milliseconds.
