Moving between Windows and Unix shells
7 ordered steps, from Windows to Zsh.
Operating systems and shells
-
Step 1: Windows
Windows starts the path because many learners begin with its filesystem, terminal defaults, and path conventions.
-
Step 2: PowerShell
PowerShell is the native automation layer the learner meets first when running commands seriously on Windows.
-
Step 3: Bash
Bash enters as the contrasting Unix shell, making command syntax and scripting assumptions visible.
-
Step 4: WSL
WSL matters after Bash because it explains how Linux shell workflows can run inside a Windows development setup.
-
Step 5: Linux
Linux gives WSL its operating-system context and prepares the learner for servers, containers, and common deployment environments.
-
Step 6: macOS
macOS broadens the Unix-like development picture and explains why many shell conventions transfer across developer machines.
-
Step 7: Zsh
Zsh closes the path because it is the default interactive shell many macOS users encounter after learning the Bash baseline.
