photo of broken ls formatting
After using cat to print a file to the screen (/boot/loader.efi in this case) subsequent uses of ls (with no switches) produces output that is not aligned.
This is reproducible and requires a system reboot to correct.
I'm using 10.1-RELEASE which has been clean installed.
Don't know if you are fooling around but in case you aren't:
Binary data can always mess up your terminal as there may be control characters in it, which your terminal interprets.
You need to use "cat -v" when displaying binary files or call "reset" or "stty sane" afterwards to clean up your terminal. This may work.
if you need to see binary data use xxd etc.
This is not a bug.
Updated 10.1-BETA and 10.1-RC versioned bugs to 10.1-STABLE.
As the last reply suggests, this is expected behavior.
