#sh(command, output = STDOUT) ⇒ Object

Execute a shell command with reporting. The command itself is logged, then output from both stdout and stderr, then a success or failure message. Raises CommandError on error.

If output is STDOUT (the default), no redirection occurs. In all other cases, both stdout and stderr are redirected to output. In these cases, formatting (colors, highlights) may be lost.

:command: [String] A shell command to execute :output: [IO] An optional IO object to receive stdout and stderr from the command
