I'm wondering whether the error message has been copy-pasted or there has been a confusion from the OP. BTW, I'm surprised by the change of the error message: $ ls -K ls: invalid option -- 'K' Try 'ls --help' for more information. $ ls --K ls: unrecognized option '--K' Try 'ls --help' for more information. Ditto with busybox ls. -- Vincent Lefèvre <[email protected]> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / Pascaline project (LIP, ENS-Lyon)
