Power Shell – Containment Operators

Power Shell Containment Operators The containment operators (-contains and -notcontains) are similar to the equal operators. However, the containment operators always return a Boolean value, even when the input is a collection. The conditional operator -Contains is similar to -eq, except it returns ‘True’ or ‘False’. -Contains is designed for situations where you wish to test for one particular…

Do-While & Do-Until Loop in PowerShell Loops are an essential construct in any programming language as they enable a block of code to be repeatedly executed based on the condition. This can be useful for iterating through items in an object or repeatedly performing an operation. PowerShell supports involves setting a condition which either allows the loop to process as long as the condition is…

Power Shell – Type comparison

What is comparison Operator? Comparison operators let you specify conditions for comparing values and finding values that match specified patterns. To use a comparison operator, specify the values that you want to compare together with an operator that separates these values. Type comparison The type comparison operators (-is and -isnot) are used to determine if an object is a specific type.…

PowerShell – Replacement Operator

Replacement Operator PowerShell provides several options to help you replace text in a string with other text. The -replace operator replaces all or part of a value with the specified value using regular expressions. It replaces every occurrence of the exact string you specify with the exact replacement string that you provide. The -replaceoperator provides much more flexibility because its…

PowerShell – Equal Operators

Equal Operators: The equal operators return a value of TRUE if its identical or return a value of FALSE if it is not identical. The entire pattern must match an entire value. By default, all comparison operators are case-insensitive. To make a comparison operator case-sensitive, precede the operator name with a “c”. For example, the case-sensitive version of -eq is -ceq. To make the…

Comparison Operators and Conditional Logic Comparison operators let you specify conditions for comparing values and finding values that match specified patterns. To use a comparison operator, specify the values that you want to compare together with an operator that separates these values. Equality Operators  Description -eq equals -ne not equals -gt greater than -ge greater than or equal -lt…

By default, PowerShell assumes that the elements of an array are of the type variant. This means that you can mix different data types—that is, combine numerical values, dates, or strings in a single variable. The data elements of a PowerShell array need not be of the same type, unless the data type is declared (strongly typed). However, if you think to restrict an array to a certain data type…

Same like other programming language, the comments in Powershell will not executed. Comments can be added to explain the function of the code. The powershell also supports single line and multi line comments. Single Line Comments SYNTAX: # The comment with the # will handling single line comments. In PowerShell single line comments start with a hash symbol and everything to the right of the #…
