nu
Nushell ("a new type of shell") takes a modern, structured approach to your command-line.
TLDR
Start an interactive shell session
$ nu
Execute specific commands
$ nu --commands "[echo 'nu is executed']"
Execute a specific script
$ nu [path/to/script.nu]
Execute a specific script with logging
$ nu --log-level [error|warn|info|debug|trace] [path/to/script.nu]
