Master the move-item cmdlet in PowerShell and learn to move an item, including its properties, content, and child items, using path and destination parameters to a new location.

Learn how the Get-Item cmdlet retrieves the item at a location, uses the asterisk wildcard to return all content, and navigates different data stores with PowerShell providers.

Discover how the set-content commandlet writes or replaces file content using path and value parameters, with hands-on examples creating and verifying a testing file.

Learn how to use the Get-Content cmdlet to read file content line by line, use path, total count, and other parameters, with practical examples in PowerShell.

Learn how the add-content cmdlet appends content to a specified item or file by specifying a path and value, with examples showing appending 'world' to testing.txt and verifying with get-content.

Clear-content deletes a file’s contents without removing the file itself, and you can inspect parameters like path and include with get-help.

Discover advanced for each object cmdlet usage, pipe input objects, and apply the process parameter to perform per-item operations, as shown by an example dividing numbers by ten.

Explore how a PowerShell pipeline links simple commands into a chain, sending the output from Get-Process to Stop-Process to stop the Notepad process on the local computer.

Learn how to use read-host to prompt for console input, capture passwords as secure strings, set prompt messages, store results in variables, and verify entered values in PowerShell.

Master the Get-ChildItem cmdlet to list items in a path, explore depth and recurse controls, and use Get-Help for parameter guidance when inspecting directories.

master PowerShell operators, including arithmetic, assignment, comparison, logical, redirection, and split and join; learn how they perform calculations, assign values, compare data, connect expressions, and route output.

Explore arithmetic operators in PowerShell for numeric calculations, including addition, subtraction, multiplication, division, and modulus, and see how addition concatenates strings, and multiplication repeats inputs in arrays and hash tables.

Demonstrate the PowerShell assignment operator to assign single or multiple values to variables, and use addition assignment to add numbers or append strings like micro and soft to form Microsoft.

Explore PowerShell comparison operators, including equality, matching, and containment, and learn how to test values using equal, greater than, less than, like, contains, and match operators.

Explore the split and join operators in PowerShell, and see how to declare a string array and join its elements into a single string in order.

Explore the logical operators in PowerShell to connect expressions and yield true or false. Use and, or, not, xor, and exclamation to test multiple conditions with clear true results.

Redirect PowerShell output to text files using the greater than, double greater than, and n greater than ampersand one operators, shown saving Get-Process output to alpha.txt with notepad.

Master PowerShell conditional statements by exploring if, else if, and else, including nested if and switch statements to test boolean expressions and equality against a list of values.

Master PowerShell conditionals with if statements that run code when a boolean expression is true, using curly brace blocks and an example that checks even numbers.

Use the if else statement to execute actions based on a boolean condition in PowerShell. The example checks if a number is even or odd using modulus and prints result.

Master the else if ladder in PowerShell by using if, else if, and else to evaluate multiple conditions, demonstrated with a number being positive, negative, or zero.

Master PowerShell's switch statement to evaluate multiple conditions with a clean, case-based syntax, including break control and optional default, demonstrated through an input-to-word example.

Explore how to execute code blocks in PowerShell using for, foreach, while, and do while loops. Learn how each loop tests conditions and traverses collections, including arrays, to streamline repetition.

Demonstrates the do while loop in PowerShell, an exit control loop that runs the block first. The example prints 1 through 10 using a postfix increment to update i.

Learn how to use the for each loop in PowerShell to iterate over arrays and collections, printing each item as the loop runs.

Learn how the for loop in PowerShell executes a code block when a condition is true, with syntax showing initialization, test expression, and increment, illustrated by printing 1 to 10.

PowerShell made easy: looping part 5 explains the while loop, an entry control loop that repeats a code block while a condition is true, with a 1–5 counter example.

Explore how arrays store values in a single variable and use zero-based indices to access elements of any type in PowerShell.

Explore how the array subexpression operator in PowerShell creates an array from the statement inside it, yielding 0 or more objects with examples using hello there, a blank, and Get-Process.

Learn to create and initialize arrays in PowerShell, assign multiple values, and verify contents by printing. Use the range operator 1..7 to generate values.

Learn to read a PowerShell array, display all elements, access items by index (0 for first, 3 for fourth), and slice a range (5 to 9) with the range operator.

Learn to iterate over arrays in PowerShell using foreach, for, and while loops, declare arrays, and print elements to the console with range operators and length-based indexing.

Learn how hash tables in PowerShell store key-value pairs as a hash table object, with efficient lookups, flexible dotnet object types, and contrast with order dictionary’s preserved insertion order.

Learn to create and populate a hash table in PowerShell by declaring a variable, using the hash table syntax with curly braces, and adding key-value pairs with quoting and separators.

Learn how to create and inspect an ordered dictionary in PowerShell by using the ordered attribute, compare with a hash table, and see how keys retain insertion order.

Display a hash table stored in a variable as a two-column table of keys and values, and use dot notation (variable.keys, variable.values) to list all keys and all values.

Learn how to access hash table values by key, use square brackets with quotes for string keys, check the count property, and understand that hash tables are not arrays.

Learn how to create aliases in PowerShell with the New-Alias commandlet, save them to a file with export, and retrieve them later with Import alias Commandlet; explore parameters with Get-help.

Explore the Get Alice command to list aliases in the current PowerShell session, including built-in and profile-added aliases, and learn to query by name or exclude with get-help for details.

Export aliases from the current PowerShell session to a file using the export alias command, with CSV output and options to add to a session or to a PowerShell profile.

Explore regex basics in PowerShell, including match, replace, and split operators. Learn case-insensitive patterns, character classes, anchors, and practical examples with literals and groups.

Discover how to apply regex character ranges in PowerShell, using patterns like [0-9] to match digits and the match operator, with examples that return true for numbers such as 42.

Use the slash w subexpression to match word characters in PowerShell regex. The match operator returns true for the first word character, B, within A–Z and 0–9.
