"DS Commands" – Need Context to Answer (Nintendo DS, Data Structures, Data Science, DSP, Deep Learning, Directory Services, Docker Swarm)

"DS" is ambiguous. Please specify which domain:

• Nintendo DS/3DS: Homebrew commands (devkitPro, libnds), Action Replay codes, twltool, GodMode9 scripts.
• Data Structures (CS): Operations on stacks, queues, trees, graphs (push, pop, enqueue, dequeue, traverse).
• Data Science / Pandas: df.describe(), df.groupby(), df.merge(), df.pivot_table().
• Digital Signal Processing: FFT, FIR/IIR filter design, MATLAB/Python scipy.signal functions.
• Deep Learning (PyTorch/TensorFlow): torch.nn, tf.keras layer APIs.
• Directory Services (Microsoft): dsquery, dsget, dsmod, dsmove, dsrm.
• Docker Swarm: docker service, docker stack, docker node commands.

Reply with your context (platform, language, goal) and I'll give precise commands.
