In error messages, raw non-printable characters from arguments should not be output without transformation, at least if this is on a terminal. If stderr has been redirected, this is more a matter of choice.
An example: type "cd /^M" where ^M is a CR character (e.g. obtained by typing ^V ^M). One gets on the terminal: : No such file or directory which is not very informative. This leads to this kind of questions: http://unix.stackexchange.com/questions/154408/cant-cd-to-home-user-when-sourcing-a-script IMHO, in this case, bash should do like zsh, which replaces the CR character by the character sequence "^M". -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
