Just add a corner case here  It might save you 5 minutes  If you use a chain of actions  you need to put     at the end of line  leave a space followed by the      backtick   I found this out the hard way     yourString    HELLO world  POWERSHELL                        Replace  HELLO    Hello                        Replace  POWERSHELL    Powershell

You can use a space followed by the grave accent  backtick    Get-ChildItem -Recurse     -Filter   jpg       Select LastWriteTime   However  this is only ever necessary in such cases as shown above  Usually you get automatic line continuation when a command cannot syntactically be complete at that point  This includes starting a new pipeline element   Get-ChildItem     Select Name Length   will work without problems since after the   the command cannot be complete since it s missing another pipeline element  Also opening curly braces or any other kind of parentheses will allow line continuation directly    x 1  5  x    0 3            Number          Similar to the   a comma will also work in some contexts   1  2   Keep in mind  though  similar to JavaScript s Automatic Semicolon Insertion  there are some things that are similarly broken because the line break occurs at a point where it is preceded by a valid statement   return   5   will not work   Finally  strings  in all varieties  may also extend beyond a single line    Foo bar    They include the line breaks within the string  then

If you are trying to separate strings into multiple lines  you can use the      For example    header       Make                    ComputerName                    Model                    Windows Version    Will look just like    header    Make ComputerName Model Windows Version

To expand on cristobalito s answer   I assume you re talking about on the command-line - if it s in a script  then a new-line  gt acts as a command delimiter  On the command line  use a semi-colon      For example  Sign a PowerShell script on the command-line  No line breaks  powershell -Command  quot  amp   cert Get-ChildItem    Path cert  CurrentUser my -codeSigningCert   Set-AuthenticodeSignature -filepath Z  test ps1 -Cert  cert

In PowerShell and PowerShell ISE  it is also possible to use Shift   Enter at the end of each line for multiline editing  instead of standard backtick

I just found out that there must not be any character between the back tick and the line break  Even whitespace will cause the command to not work

Just use   character to separate command on multiline

Use a semi-colon   to separate command  Replace double backslash    on any backslashes     Use    for passing safe address to switch command like   PATH      This ps1 command install locale pfx certificate   powershell -Command   pfxPassword   ConvertTo-SecureString -String  12345678  -Force -AsPlainText   Import-PfxCertificate -FilePath   C   Program Files  VpnManagement  resources  assets  cert  localhost pfx   Cert   LocalMachine  My -Password  pfxPassword   Import-PfxCertificate -FilePath   C   Program Files  VpnManagement  resources  assets  cert  localhost pfx   Cert   LocalMachine  Root -Password  pfxPassword

There s sooo many ways to continue a line in powershell  with pipes  brackets  parentheses  operators  dots  even with a comma   Here s a blog about it   https   get-powershellblog blogspot com 2017 07 bye-bye-backtick-natural-line html  You can continue right after statements like foreach and if as well

In most C-like languages I am deliberate about placing my braces where I think they make the code easiest to read   PowerShell s parser recognizes when a statement clearly isn t complete  and looks to the next line  For example  imagine a cmdlet that takes an optional script block parameter        Get-Foo                    if the script block is very long  you might want to write        Get-Foo                                                                                       But this won t work  the parser will see two statements  The first is Get-Foo and the second is a script block  Instead  I write        Get-Foo                                                                                   I could use the line-continuation character     but that makes for hard-to-read code  and invites bugs     Because this case requires the open brace to be on the previous line  I follow that pattern everywhere        if  condition                             Note that if statements require a script block in the language grammar  so the parser will look on the next line for the script block  but for consistency  I keep the open brace on the same line    Simlarly  in the case of long pipelines  I break after the pipe character             project Items                   Key -eq  ProjectFile                      Value                     EvaluatedInclude
