Class Method Summary

• .run(cmd) ⇒ Object

  Run a shell command string.

Class Method Details

.run(cmd) ⇒ Object

Run a shell command string. On Unix uses sh -c; on Windows uses COMSPEC (usually cmd.exe /c) so we do not require a POSIX shell (avoids Errno::ENOENT for sh on plain Windows). Prints ✓ (green) + cmd on success, or ✗ (red) + cmd then stdout/stderr on failure. Returns the Command with result fields set.
