--help and help are successful commands so output should not go to error. QE teams have requested this change, also users doing docker help | less or docker run --help | less would expect this to work. Usage statement should only be printed when the user asks for it. Errors should print error message and then suggest the docker COMMAND --help command to see usage information. The current behaviour causes the user to have to search for the error message and sometimes scrolls right off the screen. For example a error on a "docker run" command is very difficult to diagnose. Finally erros should always exit with a non 0 exit code, if the user makes a CLI error. Docker-DCO-1.1-Signed-off-by: Dan Walsh <dwalsh@redhat.com> (github: rhatdan) |
