Thanks for the report. However, this is not a bug in dirname, but in your usage pattern. You are invoking "dirname -bash", which dirname (rightly) interprets as the attempt to be the -b option, but dirname does not have a -b option. You need to use -- to mark the end of options and the start of arguments: dirname -- "$0" > dirname (GNU coreutils) 5.97 Wow, that's old.
