PowerShell String

Introduction to String in PowerShell

As we have already discussed that PowerShell is build on .Net Framework. According to the .NET definition of string – “A string is a sequential collection of characters that is used to represent text”.

The PowerShell string is simply an object of System.String type.

How to Define String


Anything mentioned within single quote or double quote considered as string in PowerShell.


Only difference between the two is that strings in double quote support string expansion, while a single quote will only represent literal strings.


Operations on String


To find out what operation can be performed on string, Use Get-member command which will return all methods applicable to string.


Length of String


Length property will return the number of characters in string. 


Split Operations on String


Split operation will divide string into multiple line from where split character is present. Lets take our environment PS module path example,


Apply split operation on ';' character.


Similarly, we can use different split characters to divide the string into the desired output.

Join Operations on String


The concatenation of the string is performed using the plus Sign.


We can also use join operator to concatenate multiple strings.


You can also join the string with the Concat method


Substring Operations on String


Substring command in a string is used to extract the part of the string. It totally works on indexing. In a string, the index starts from 0.


First parameter is starting index and second is number of characters to be returned.

Trim Operations on String


Trim operation in PowerShell is used to trim or remove the space or the specific characters from the beginning and the end of the string. For example,

When you use only Trim() function on the string then it will remove the space
from the beginning and the end of the string.


TrimStart() and TrimEnd() functions, which remove the space or the specific character from the beginning and the end of the string respectively.

Case Operations on String


We can convert the entire string into the Upper case or the Lower case.

Index Operations on String


Index operation in a PowerShell used to find the position of the particular character in the string. Indexing starts at 0. IndexOf() operation finds the first occurrence of the character.


LastIndexOf() finds the last occurrence of the character.

Replace Operations on String


To replace the specific character or set of characters, there is a Replace operation available. This operation is not case sensitive.


You can replace the space with a specific character.


We can replace the word as well.

Contains Operations on String


Contain function when applied on a string, it checks if the specific word exists in the string or not. This function is case sensitive. The output will be TRUE / FALSE.



As function is case sensitive, False returned second time.

Managing CSV Files using Import/Export-CSV in PowerShell We have two important cmdlets import-csv/export-csv which are widely used while working with CSV. Before moving to how to manage these type of files, First look at what is CSV file: A Comma Separated Values ( CSV ) file is a plain text file that contains a list of data. These files are often used for exchanging data between different applications. For example, databases and contact managers often support CSV files. A CSV file has a fairly simple structure. It’s a list of data separated by commas as you can see in below screenshot. We have file "email.csv" having email address and name separated by comma. You can use notepad/excel to open thses file. Now lets move back to our main topic, how to manage csv files with PowerShell.  Reading CSV Files with Import-Csv Importing of csv file is pretty straight forward. First move to

PowerShell Arithmetic Operators

Image
In this tutorial we will see about PowerShell Arithmetic Operators and how PowerShell is dealing with them. Arithmetic operators are used to perform numeric calculations. As well as numeric calculations, the addition operator may also be used with strings, arrays, and hashtables. Multiplication operator may also be used with strings and arrays. Below is the list of PowerShell arithmetic operators. Operator Description Example + Adds numeric values 4 + 6 concatenates a string, arrays, and hash tables “CS” + “Tutorials” – Subtracts numeric values 4 – 2 Makes a number negative -98 * Multiple numeric values 4 * 2 copy string, arrays to the specified number of times “!” * 4 / Divides numeric values 4 / 2 % Gives remainder after division 7 % 3 For live demo, watch below video. I have demonstrated the use of PowerShell arithmetic operators by  creating calculator. Along with operators, Switch statement and While loop also used.

You can also store GUID into a variable like below If you want to get GUID as string, use ToString  method or Guid  property. Both return output of string type, you can verify this using Get-Member .
