Three Ways to Split String in PowerShell

This post is to summarize three ways to split a string in PowerShell.

In the following example
$t = “1000ABC2000abc"
[regex]$rx1 = “\d+”
[regex]$rx2 = “ABC"

• Using a regex object’s split method
  • In this method, the regex works and the match is case-sensitive
    
    PS > $rx1.split($t)
    
    

    ABC
    abc

    PS > $rx2.split($t)
    1000
    2000abc

    
    
• Using a string object’s split method
  
  • In this method, the regex does not work and the match is case-sensitive
    
    PS > $t.split($rx1)
    1000ABC2000abc
    
    

    PS > $t.split($rx2)
    1000
    2000abc

    
    
• Using a string object’s split operator
  • In this method, the regex works and the match is case-insensitive
    
    PS > $t -split $rx1
    
    

    ABC
    abc

    PS > $t -split $rx2
    1000
    2000
