Table 1 Linux Commands
1. How do these commands differ from using the Command Prompt in Windows?
Linux has access to source code and alters the code per the user.
Windows does not.
2. How do these commands differ from using the PowerShell in Windows?
Linux has a text-based command-line interface.
Powershell uses interactive graphical command-line
interface.
