from one of the answers: > set -f And why does `set` use a flag with no argument after it? It's simple, just follow the rules: Single dash for single letter flags Double dash for full word flags No dash for flag arguments No dash for some non-flag arguments from ancient commands Sometimes the dash is a "minus" prefix and has a matching "plus" prefix for a non-flag argument Gang them all together sometimes Git uses lots of subcommands and flags, often in surprising combinations Not always can you gang together single letter flags ? Can you always gang together single letter flags? I'm not really sure TBH Never gang together full word flags. The short pneumonic "SDNNSGGN?N" is instructive here. The trouble you'll have remembering that pneumonic will remind you how much of a pain bash is.
