Once I have the alias of those groups, I want to strip off the "Full" portion so that I wind up with the alias of the mailbox it is connected to. $Full = Get-DistributionGroup -ResultSize Unlimited | Where | Select Alias Those group Display Names all end in "-Full" so it's a pretty easy query. I did a search for all mail-enabled security groups in our Org that we are using as ACLs for Shared Mailboxes. In contrast, the comparable call with Equals returns True: ("Hello world").Equals("Hello" + " " + "world") In the above example, CompareTo returns 0 because the strings are identical. ("Hello world").CompareTo("Hello" + " " + "world")
If the first string is “bigger” than the second string (that is, if it comes first in the sort order), the cmdlet returns 1 if the first string is smaller, the result is ‑1. String objects also offer methods for this purpose. Primarily, this includes -eq and -ne, as well as -like, which supports wildcards. In general, you can work with the same comparison operators as for numerical values to determine differences between strings. Searching and replacing characters in PowerShell Comparing strings ^ To calculate the position of a character or substring in the string, IndexOf is at your disposal: ("Hello world").IndexOf("ll") Likewise, Contains tells you if a string contains a certain substring: ("Hello world").Contains("ll") For instance, StartsWith and EndsWith determine whether a string begins or ends with a certain character or string, respectively. However, PowerShell supports several methods that specialize on a particular search type. ("Hello World").Replace("Hello","New")Ī counterpart to the -match operator doesn’t exist. Replace is the simplest of these methods and doesn’t support regular expressions. Of course, each of these methods has its specific purpose. In addition, the string object offers several methods for this task. For the more demanding tasks, regular expressions are available, which can be applied with the -match or -replace operators. PowerShell knows a variety of techniques to find and replace substrings. To eliminate leading or trailing spaces, you can use TrimStart, TrimEnd, or Trim. In this example, “llo” is removed from “Hello world.” It deletes the specified range from the string: ("Hello world").Remove(2,3) The counterpart method to Substring is Remove. This command results in “llo w”, which corresponds to the substring with a length of five characters that begins at the third character (counting begins at 0!). However, instead of using delimiters, you have to specify the position and length of the string that you want to extract: ("Hello world").Substring(2,5) The method Substring has a similar purpose because it can extract a part of the string. The result array in the above example has two elements. PowerShell will then produce an array with the corresponding number of elements: ("Hello world").split("ll"" ", 2) You can specify the maximum number of substrings in which the string is split. The delimiter itself falls by the wayside: ("Hello world").split("ll"" ") In the following example, the string is split at the double “ll” and at the space. The former is simpler and only allows for use of explicit delimiters the operator, on the other hand, supports regular expressions. If you don’t like the result “Helloworld” in the example and you want to add a space between the two words, you have to call -join this way: $h,$w -join " " Splitting strings ^įor the opposite task (that is, for splitting strings), you can use either the split method or the split operator. Normally, you place the operator in front of the string unless you want to separate the strings with a delimiter after the merge: -join($h,$w) Its usage is perhaps a bit counterintuitive. PowerShell automatically inserts a space here between the linked array elements.Īnother option for concatenating strings is the join operator. This method is also suitable for concatenating the elements of a string array: $st = hello", " world") However, you could insert any other delimiter. In the example, the space guarantees that the two words don’t stick together. Alternatively, you can expand the two strings within double quotes: "$h $w"
