PowerShell Split String on First Occurrence of Substring

Using the PowerShell String built-in Split() method or split operator, you can split a string on the first occurrence of a substring or character.

Using the split operator in PowerShell, it can return the maximum number of substrings based on the pattern. PowerShell String Split() method also split the string based on a specified substring or character and returns multiple substrings.

In this article, we will discuss how to use the PowerShell string Split() method and split operator to split a string on the first occurrence of a substring or character.

PowerShell Split() – Split String on First Occurrence of Substring

Use the PowerShell string Split() method to split the string on the first occurrence of substring and returns the first occurrence substring and second substring after the split.

$sysdate = "01-08-2022"

# Split the string on First Occurrence of substring
$sysdate.Split([string[]] "01-",[System.StringSplitOptions]"None")[1]

In the above PowerShell script, the $sysdate variable stores the date. To split the string of the first occurrence of a substring, we used the PowerShell string Split() method.

The Split () method takes substring 01- and breaks the string into multiple substrings. It split the string on the first occurrence of 01- substring and returns the remaining part as a substring.

The output of the above PowerShell script to split a string on the first occurrence of substring returns 08-2022 as a substring.

PS C:\> $sysdate = "01-08-2022"                                                                                         

PS C:\> $sysdate.Split([string[]] "01-",[System.StringSplitOptions]"None")[1]

Split Operator to Split String on First Occurrence of Character in PowerShell

Use the PowerShell split operator to split a string on the first occurrence of a character. It splits the string that matches the first occurrence in the given string and returns a substring.

$sysdate = "01-08-2022" 

# Split a string on first occurrences of character
$day,$month_year = $sysdate -split '\-' ,2  

$day 
$month_year

In the above PowerShell script, the $sysdate variable stores the date. To split the string on the first occurrence of a character Hyphen (-), we used the split operator.

The output of the above PowerShell script to split a string by Hyphen delimiter for the first occurrence returns 08-2022 as a substring.

PS C:\> $sysdate = "01-08-2022"                                                                                         

PS C:\> $day,$month_year = $sysdate -split '\-' ,2                                                                      

PS C:\> $day

PS C:\> $month_year
