• find and xargs exit codes: find's coarse 0/>0 versus xargs's 123-127 ladder

  find only promises 0 for full success and any value above 0 for an error, deliberately without finer detail, while xargs defines a specific ladder for how the invoked command failed: 123 for an ordinary non-zero exit, 124 for exit 255, 125 for killed-by-signal, 126 for not-invocable, and 127 for not-found. Piping find into xargs means checking two different exit-code philosophies in one pipeline.
