Powershell beginner commands

Important points before you start knowing and practice these Powershell commands.

1. Powershell commands are case-insensitive but filenames are case-sensitive
2. You will remember these commands only when you type not copy the commands.
3. Powershell file extension: “.ps1”
4. Commenting any line in PowerShell is with #(pound) symbol.
5. Variables defined using $(dollar) symbol along with the name of your variable. Ex: $name
6. Strings we can write either using the ‘ single coded string ’ or “ double coded string“
7. In general, Computer does not understand our high-level commands for many programming languages uses compilers and interpreters to compile high level to a computer that understands the format. In Powershell, have a similar but first it stores/checks in AST (Abstract Syntax Tree) — Stores in memory and then runs. Before the computer runs first Powershell checks here and if everything is good then the computer runs.
8. An important command is Get-Help -Name “<Nameofyourcommand”> -Full => You will know detailed information about the command. Ex: Write-Output

Command 1: To create a new file

New-Item <fileName>.ps1

Command 2: To add script inside the file
