The discussion focuses on the correct usage of the Linux `rm` command to remove files that start with a hyphen ("-"). Users encountered issues when attempting to delete files like "-file1.txt" using the command `rm -file1.txt`, which resulted in errors. The solution provided is to use `rm -- -file1.txt`, where the double dash ("--") indicates the end of command options, allowing the command to recognize the file name correctly. Additionally, users are encouraged to consult the man pages for further clarification on command usage.
