What exactly is exit in PowerShell

Question

You can exit PowerShell by typing exit  So far so good  But what exactly is this   PS Home   gt  gcm exit Get-Command   The term  exit  is not recognized as the name of a cmdlet  function  script file  or operable program  Ch eck the spelling of the name  or if a path was included  verify that the path is correct and try again  At line 1 char 4   gcm  lt  lt  lt  lt   exit       CategoryInfo            ObjectNotFound   exit String   Get-Command   CommandNotFoundException       FullyQualifiedErrorId   CommandNotFoundException Microsoft PowerShell Commands GetCommandCommand   So it s neither a cmdlet  function  script or program  It leaves the question what exactly it is   This unfortunately also means that one can t create aliases to exit   PS Home   gt  New-Alias  D exit PS Home   gt   D Cannot resolve alias     because it refers to term  exit   which is not recognized as a cmdlet  function  operable prog ram  or script file  Verify the term and try again  At line 1 char 2      lt  lt  lt  lt        CategoryInfo            ObjectNotFound     String      CommandNotFoundException       FullyQualifiedErrorId   AliasNotResolvedException   Are there any more such commands which are no commands   ETA  Just for reference  I know I can simply wrap it into a function  My profile has the lines    exit with Ctrl D iex  function    char 4    exit      in them  My question was just to know what exactly this command is

It s a reserved keyword  like return  filter  function  break     Reference  Also  as per Section 7 6 4 of Bruce Payette s Powershell in Action      But what happens when you want a script to exit from within a function defined in that script      To make this easier  Powershell has the exit keyword    Of course  as other have pointed out  it s not hard to do what you want by wrapping exit in a function   PS C   gt  function ex exit  PS C   gt  new-alias  D ex
