#### start(process)

> starts a process by name. It will not wait for the output and will continue to run, it will not block the current used Thread. The Method Start will append the Process to the system Processes instead of waiting for its output or blocking the thread.

Example

start(“firefox”)

start(“telegram-desktop”)

—

#### startAndWait(process)

> starts a process by name. It will wait for the output and will not continue to run, it will block the current used Thread until the process finishes. Finally if the process finishes the method will return the exit code and output.

Example

startAndWait(“kate”)

output = startAndWait(“tree”)

—
