Infinite wait

• (Shell) Implementing an infinite wait in shell scripting

$ sleep inf

Waits indefinitely until a SIGTERM signal is received. Using sleep 1 in a loop wakes the CPU every second, so it is not ideal.

Examples

TypeScript Promise

/**
 * Creates a promise that resolves to null after some time.
 */
export async function sleep(time: number): Promise<null> {
  return await new Promise((accept) => {
    setTimeout(() => accept(null), time)
  })
}
