The powershell like operator in PowerShell provides a simple way to perform string hasbro nerf and filtering. While you can use the -eq and -contains operators for basic string matching, the -like operator offers more flexible and powerful wildcard pattern matching capabilities, powershell like. In this comprehensive guide, we will explore everything you need to know about like in PowerShell, including its syntax, operators, and advanced usage of -like to find text patterns in strings and filter collection objects. By the end of this guide, you will be able to master the PowerShell like and improve your PowerShell skills.

At this point, I am always confused as to which comparison operator to use. From a logical language perspective I always feel like -contains is the way to go, but then I remember that might not be the correct choice. To put this issue to bed once and for all at least for myself , here is a summary of when to use -like and when to use -contains. So back to my initial requirement of determining if a string contains a particular value or not, we would use the -like operator. See some examples below:. In example 1, the result is false because there are no wildcards, therefore its checking to see if the string matches exactly. This essentially means check if xyz exists at the beginning of the string and then ignore the rest.

You can use them to create word patterns in commands. Wildcard expressions are used with the -like operator or with any parameter that accepts wildcards. Wildcard expressions are simpler than regular expressions. You can include multiple wildcard characters in the same word pattern. For example, to find text files with names that begin with the letters a through l , type:. There may be cases where you want to match the literal character rather than treat it as a wildcard character. Many cmdlets accept wildcard characters in parameter values. The Help topic for each cmdlet describes which parameters accept wildcard characters. For parameters that accept wildcard characters, their use is case-insensitive. You can use wildcard characters in commands and script blocks, such as to create a word pattern that represents property values. For example, the following command gets services in which the ServiceType property value includes Interactive. In the following example, the If statement includes a condition that uses wildcard characters to find property values. If the restore point's Description includes PowerShell , the command adds the value of the restore point's CreationTime property to a log file.

Like many other comparison operators, -like returns different results, depending on if the object it acts upon is scalar or an array. But if we pass it an array, then the result will consist of the elements, that meet the condition. Besides simple comparisons, -like and -notlike operators can be used to specify more complex expressions. As you can see, there are services that depend only on RpcSs, and services, that require some additional services.

String comparisons are case-insensitive unless you use the explicit case-sensitive operator. To make a comparison operator case-sensitive, add a c after the -. For example, -ceq is the case-sensitive version of -eq. To make the case-insensitivity explicit, add an i after -. For example, -ieq is the explicitly case-insensitive version of -eq. String comparisons use the InvariantCulture for both case-sensitive and case-insensitive comparisons.

This can be useful in situations where you need to dynamically construct a pattern based on user input or other variables. The -contains comparison operator is used to determine if a collection of objects e. The first example is an easy one, an array with each object being a string and therefore makes the comparison really easy. Well because we are attempting to find an object based on a single property, name. Wildcard expressions are used with the -like operator or with any parameter that accepts wildcards.

The following examples do the same thing that the examples for -contains and -notcontains do, but they're written with -in and -notin instead. Here is another example of using -Or operator:.

PowerShell does a culture-insensitive string conversion. These operators stop comparing as soon as they detect the first match, whereas the equality operators evaluate all input members. The output is an empty array. In this example, the value 1 is converted to a string to be compared to string '1. Related Posts. Follow-up As usual with my scripts, the mission is to get you started.
