No bug, but expected behavior - similar to: https://www.gnu.org/software/coreutils/faq/coreutils-faq.html#How-do-I-remov... "Since the file name begins with a ’-’ it looks like an option to the command. You need to force it to not look like an option. Put a ./ in front of it. Or give it the full file name path. Or tell the command you are through with options by using the double dash to end all option processing. This is common to most traditional Unix commands."

That's really very old behavior - there was no change for that in the past few decades at least. Once one is fallen in that trap, he/she will ever remember. Just imagine files like "-rf" or "--help". While the former would e.g. let rm(1) remove recursively, the latter could make a command in a script return with exit status 0 although it would/should fail. Thorough quoting/escaping arguments is key.

Now I get it, it was because the one file started with a "-", renamed it without the "-" and all is OK.

Let me try to explain the full story. The key information is that unlike in the old times of MS-DOS, the wildcards are expanded by shell and this happens _before_ the argument list is passed to the program. Therefore if you have (only) e.g. a.txt, b.txt and c.txt in current directory, there is no difference between ls -l *.txt ls -l a.txt b.txt c.txt (if there is a matching name with spaces, you would have to escape it on second line). Names starting with a dash behave the same so with "-a" and "foo", there is no difference between ls -l * ls -l -a foo and the command has no way to recognize that "-l" is an option actually entered and "-a" is not.

Sure, because you have a file named "-23133 Safe...mp4" and you do not have a file named "-23133 Safe.png". The command line "ls *.mp4" expands to something like: ls -23133 Safe Shutdown for Raspberry Pi with Super Capacitors.mp4 The New Frontier A Gentle Introduction to Rust - Matthew Gathu.mp4 The "ls" command never sees the asterisk, it is expanded. And yes, this is standard behaviour in unix or linux since ever. I don't like it, but that's how it is. You can probably run a trace and find out. It is bash which is doing this, not konsole. Try xterm, it will be the same. -- Cheers / Saludos, Carlos E. R. (from 15.1 x86_64 at Telcontar)

As already said: there is a file with a name that starts with "-2". To see what would be executed, just prepend the whole ting with "echo": $ touch ./-2badname.mp4 good.mp4 $ ls -l *.mp4 ls: invalid option -- '2' Try 'ls --help' for more information. $ echo ls -l *.mp4 ls -l -2badname.mp4 good.mp4 Have a nice day, Berny -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
