just want to share an interesting or rather accidentally discovered bug for Unix 'rm' command. I have accidentally created the file named '--help'. However, when I try to delete using rm command, it does not work and it shows up the help menu for rm instead. Same to mv command, I want to rename it to a valid filename, it shows the help menu of mv.
[Answer] To delete the file named '--help', try to use 'find' command.
Thanks for your reading and I hope it somewhat helps.
