Catalina 10.15.3 / bash / no such file or directory

What did the mkdir command look like? If it was something like

mkdir /123/some-sub-dir
mkdir: /123: No such file or directory

you would get an error just like you are seeing

Basically what VikingOSX is saying, with a real world demonstration

You understand that by installing a released Python 3.8.1, and an alpha 3.9, that the linked Python 3.8.1 commands in /usr/local/bin will be overwritten by the python 3.9 links. The python3 command will be an alpha version, and python3.8 will be the released version. That is a mess to remember.

Taken literally, the mkdir /116 command interprets you wanting to create a new folder, on the root partition of the drive, not in the current directory, or even a relative directory location. Either use ./116 or ~/path/116 to either create it, or have the command rejected as:

mkdir: ./116: File exists



Hi,Are you aware Apple switched to ZSH with Catalina?
