Method: Geet::Helpers::OsHelper#execute_command

Defined in:
lib/geet/helpers/os_helper.rb

#execute_command(command, description: nil, interactive: false, silent_stderr: false) ⇒ Object

Executes the command.

If the command doesn’t execute successfully, it will raise an error.

On non-interactive runs, the stdout content is returned, stripped of the surrounding whitespaces.

description: optional string, to make the error clearer. interactive: set when required; in this case, a different API will be used (‘system()`

instead of `popen3`).

silent_stderr: don’t print the stderr output
