Fish Shell is preferred to Bash/Zsh. The following content is for Bash/Zsh only.
It suggested that you use IPython shell instead of Bash/Zsh shells. Please refer to IPython Is the Best Shell for detailed discussions. If you have to use shell commands, it is suggested that you use Linux commands when possible as Linux command are more universal and useful. You can achieve this by using WSL 2 on Windows and by using Docker or virtual machine on macOS.

[1] Windows CMD command might not work well in Windows PowerShell.
For example,
the where command sometimes works but sometimes doesn’t work in a PowerShell.
Since PowerShell becomes more popular than Windows CMD,
Get-command is recommended over where.
[2] The macOS version of fdisk does not function similar to the Linux version of fdisk. It is not as intuitive and easy to use as the Linux version. It is suggested that you use the Linux version of fdisk instead.
