Find your way around
Create a directory and verify that it exists.
A workspace you can explore
Your lab starts in /home/user. This is a virtual directory in the browser. Get-Location shows your current location, and Get-ChildItem lists its contents.
Get-Location
Get-ChildItem
An absolute path starts at the root, such as /home/user/reports. A relative path starts from your current directory. Here, ./reports points to the same place.
Create and check
New-Item -ItemType Directory -Path './reports'
Test-Path -Path './reports' -PathType Container
New-Item returns the created item. Pipe it to Out-Null when you do not need that output. Test-Path returns a Boolean: $true or $false.
Join-Path combines directory and child names without hand-building path separators. Set-Location changes the current directory.
The lab uses Unix-style paths. A Windows machine may use paths such as C:\Users\Ada; native drives and system folders are not present in this browser workspace.
Get-Location
Get-ChildItemPut it into practice.
Create a reports directory under /home/user, then output whether it exists as a directory.
See an explained solution
New-Item -ItemType Directory -Path './reports' -Force | Out-Null
Test-Path './reports' -PathType Container-Force allows the script to run again when the directory already exists. Suppressing New-Item's output leaves the Boolean check as the final result.
