Hi,

Today we are going to see what .Chars() , PadLeft() and Padright() does. And I think after covering this method there are only few methods left to cover for the next text manipulation series articles.

We are to using $text variable to show the mentioned methods.

 

$text = "The quick Brown fox"

ToCharArray()

 

The .Chars() method convert the whole string to in to the array.

$a = $text.ToCharArray()

 

As you can see in the below screenshot it spilt the whole string in to the single character. This is converted in to a array object.

How to check this is an array?

Okay! Let’s assign the above command to a another variable

$arr = $text.ToCharArray()

 

And now try to access the first object of array,the output is "T" and when we try to access the second object in the array the output is "H"

$arr[0]

$arr[1]

 

 

 

 

PadLeft()

 

The PadLeft() method basically added the specified number of space on the left of the sting, we need to specify how many black space we want to add in enclosed with bracket.

 

$text.PadLeft(200)

You can clearly see the blank spaces in the front of our original text.

 

.PadRight()

The .PadRight() does the same thing but I added the specified number of space to the right side of the string.

Hi,

today we are using .Contains() and .Equals() method on our text. The output of these methods is Boolean which mean either “True” or “False”

Lets start.

first set our $text variables , today we are going to use  3 variables "$text,$text2 and $text3”

$text = "The quick brown fox runs over the lazy dog"

$text2 = "Tommy is not a lazy dog"

$text3 = "The quick brown fox runs over the lazy dog"

 

.Contains()

.Contains() method  check for the  word which we provide in brackets in to the original string. Let me show you.

$text.Contains("brown")

I am checking that if our $text variable contains the word “brown” in it  , and yes we have “brown” word in our $text variable so the out is “True”

lets check the another example.

$text.Contains("red")

Now we are checking that if we have a “red” word in our $text variable. we know that our $text is set to  “"The quick brown fox runs over the lazy dog"” and there is no “red” in it so that’s why output is false.

.Equals()

Like .Contains(), .Equals() also give output in Boolean. .Equal() method checks that both Strings are equal or not. the syntax is .Equal and provide the string to match in brackets().

Let see the examples.

here are our $text variables

$text = "The quick brown fox runs over the lazy dog"

$text2 = "Tommy is not a lazy dog"

$text3 = "The quick brown fox runs over the lazy dog"

---------

$text.Equals("$text3")

First i am checking $text and $text3 variable. as you seen $text and $text3 are identical so the output of the .Equal() is true.

Lets check $text variable with $text2 variable.

$text.Equals("$text2")

We know that $text variable and $text2 variables are not same and when we have used the .Equal method to compare both variables the output is “False”

Use Contains() method

 

Use Equal Method

Hi,
Today we are using .replace and .remove methods to play with the string. Lets start. Today i am using some fake email id as text.
$text = Aman.Dhally@xyz.com

Replace                       
Using replace we can replace the text,symbols of our strings.  The syntax is simple Replace(“Old Character”,”new character”)
First lets replace “Aman” with some other name , for example with “SAM”,"

$text.Replace("Aman","Sam")

You can see in below screenshot that  text “aman.dhally@xyz.com” is replaced with “Sam.Dhally@xyz.com”

 

Secondly lets replace “.” with a blank spaces

$text.Replace("."," ")

In the screenshot you can se that all “.” are replaced with the “ “ a black space.

lets assume that we have a text file which contain list of all users email id in our “XYZ” company and we want to remove “@xyz.com” and keep the text before “@xyz.com” .

$text.Replace("@xyz.com"," ")

and here is the our output :) ,showing only the text before “@xyz.com”

Remove                                
Before doing anything else first lets check the length of our text using Length property. The syntax for remove method is to define to keep the number of characters and remove everything else. Not getting my point.. let ,me show to you.
Our text have 19 characters in it.

$text.Length

 

$text.Remove(4)

You can see that i mentioned 4 characters to keep and remove everything else. and the output is “Aman” which are exactly 4 characters.

$text.Remove(11)
Now i am keeping 11 characters of the string and removing everything else. and you can see that the output is  “Aman.Dhally” which are exactly 11 characters .

there is another example of Remove() method. 

$text.Remove(4,7)

In this example. first you can see our original text “Aman.Dhally@xyz.com”, in second we are keeping the first 4 characters of the text and removing everything else, so the output is “Aman”, in third we are keeping first 4 characters of the text "which is “AMAN”, and then removing next 7 characters of the text which is “.Dhally”  and then the output is “Aman@xyz.com”

Part-3: Text Manipulation in PowerShell using .StartsWith() and EndsWith() methods

 

Part-1: http://newdelhipowershellusergroup.blogspot.com/2012/01/part-1-text-manipulation-in-powershell.html | using Trim(),TrimEnd(),TrimStart()

Part-2: http://newdelhipowershellusergroup.blogspot.com/2012/01/part-2-text-manipulation-in-powershell.html | ToUpper(),ToLower()

Hi,

Today we are going to use .StartsWith() and .EndsWith() methods to play with our text.

we are using the same text which we used in previous posts and saving the text in a variable $text

$text = "The Quick brown fox jumps over the lazy dog"

 

Lets start.

.StartsWith()

This test that check that the string start with the character which we specified in .StartWith() and it give result is Boolean, the result is either “True” or “false”

lets check if our text start with “The Quick”

$text.StartsWith("The Quick")

the result is “True” , which means yes our text is start with “The Quick”

NOTE: By default the the text which we specified in  StartsWith() and EndsWith() are case sensitive. Not getting my point ? let me show you.

this is our default text. “T” in The and “Q” in Quick is uppercase.

 

this time i type all lower case character in .StartsWith() method and lets see the result

$text.StartsWith("the quick")

and this time result is false. You need take care of it if you are going to use these methods in your scripts.

lets compare.. I hope everything is clear now.

How to fix it ???

to make these methods make case-insensitive add ,1 after the text. This ,1 is in igonecase  switch which is Boolean, so 1 means is case-insensitive is ON

$text.StartsWith("the quick",1)

Bingo !!! now our condition is true.. :)

 

Lets See the comparison chart. The result are in the front of you…

 

.EndsWith()

lets check if out text ends with “lazy dog”

$text.EndsWith("lazy dog")

The result is “True” which means our text ends with “lazy dog”

as i mentioned before that the text in these Methods take as case sensitive. in our current string “lazy dog” is in lower case let try to search with “Lazy Dog”

$text.EndsWith("Lazy Dog")

as expected the result is “False”

lets make it case-insensitive by ON the IgnoreCase switch

$text.EndsWith("Lazy Dog",1)

Bingoo !!! its true now ….

want to see the comparison? I bet you want…

In the screenshot you can see the original text and the methods with ignorecase and without ignorecase switch

Thanks

Part-2: Text Manipulation in PowerShell using .ToLower and .ToUpper method

 

Part-1: http://newdelhipowershellusergroup.blogspot.com/2012/01/part-1-text-manipulation-in-powershell.html

Hi,

In part-1 of text manipulation we saw how to use .Trim(),.TrimStart() and TrimEnd() method. Today we will see how to use .ToLower and ToUpper() Method.

Lets start

we are using the same text which we used in part-1 and saving the text in a variable $text

$text = "The Quick brown fox jumps over the lazy dog"

.ToLower()

When we use ToLower() method it convert the whole string in lowercase.

Check first what $text contains.  and it contains the text which we provide to variable $text

When we run the $text.ToLower() it converted the whole string in to lower case.

 

Let’s compare it with original one. You can see it converted the whole string to lower case {actually “T” in “The” and “Q” in “Quick” is uppercase in original text}

ToUpper()

The ToUpper() method convert the whole string in to uppercase.

$text.ToUpper()

You can see that the whole string in converted to UPPER CASE :)

let compare it with our original text.

Happy????? :)

I hope it helps someone :)

Thanks

Part-1: Text Manipulation in PowerShell using Trim, TrimStart , TrimEnd methods

Hi,

Did you ever tried to use .Trim() method on a string and can’t get it working? if yes ? Then welcome to the novice group. and if no? man you are genius.

Kidding :)

i was looking for some example for it i found few but not with screenshots :) .. then i decide to write a article on it … 

So lets start.

I am using the text “The Quick brown fox jumps over the lazy dog” and put this text in to a variable $text

$text = "    The Quick brown fox jumps over the lazy dog.     "

You can see that i have a space in the the beginning of the text and the end of the text.

Lets remove these spaces to remove these spaces we are going to use trim() method.
Trim()

The Trim() remove the black characters to the right and left 

$text.Trim()

You can see that white space is removed from beginning of “the quick brown”

TrimStart()

The TrimStart() remove all the chracters from the start of the string.






If you want to remove any from the beginning of the text than we need to use TrimStart() method. Lets remove “The QUick” from the text.

$text.TrimStart("The Quick")

Now you can see in the output “The QUick” is removed from output.

not lets trim the end of the string using TrimEnd() method

TrimEnd()

The TrimEnd() remove are the characters from the string.

$text.TrimEnd("the lazy dog.     ")

You can see that now “the lazy dog.” is removed from the output.

I hope this helps someone…
