ABOUT RESERVED WORDS
SHORT DESCRIPTION
Lists the reserved words that cannot be used as identifiers because they
have a special meaning in PowerShell.
LONG DESCRIPTION
There are certain words that have special meaning in PowerShell. When these
words appear without quotation marks, PowerShell attempts to apply their
special meaning rather than treating them as character strings. To use
these words as parameter arguments in a command or script without invoking
their special meaning, enclose the reserved words in quotation marks.
The following are the reserved words in PowerShell:
assembly exit process
base filter public
begin finally return
break for sequence
catch foreach static
class from (*) switch
command function throw
configuration hidden trap
continue if try
data in type
define (*) inlinescript until
do interface using
dynamicparam module var (*)
else namespace while
elseif parallel workflow
end param
enum private
(*) These keywords are reserved for future use.
Several language keywords, including Foreach, If, For, and While, have
their own help articles. To view them, type Get-Help about_ and add the
keyword. For example, to get information about the Foreach statement, type:
Get-Help about_ForEach
For information about the Filter statement or the Return statement syntax,
type:
Get-Help about_Functions
For information about other reserved words, type:
Get-Help <Reserved_Word>
[!NOTE] Not every reserved word has its own help article. If Get-Help
does not return an article, you can search for articles that talk about
the reserved word using the following command:
Get-Help <Reserved_Word> -Category:HelpFile
