set: set shell options and positional parameters

Usage:
  set [-|+OPTION...] [-|+o NAME]... [--] [ARG...]
  set -o
  set +o

Options:
      --help  print this help

Shell options:
  Turn on an option with -o NAME or --NAME, and turn it off with +o NAME or
  ++NAME. Prefixing NAME with "no" reverses the effect, as in -o noglob.
  Each single-letter option below does the same as the -o form beside it,
  and swapping its - or + reverses the effect.

  +C  -o clobber
  -e  -o errexit
  +n  -o exec
  +f  -o glob
  -h  -o hashondefinition
