Understanding Quotes
PowerShell uses four different types of quotes. As an administrator, you are most interested in single ordinary and double ordinary quotes. A developer would be more interested in the here-strings. The four types of quotes are explained in the following table.
Single ordinary quotes:
$a="Champs"
'World $a' => World $a
|
In single quotes, variable names are not expanded and escape sequences are not interpreted. |
Double ordinary quotes:
$a="Champs""World $a" =>
World Champs
|
Inside double quotes, variable names are replaced with their values and PowerShell escape sequences are interpreted. |
Single here-strings:
$b="Two"
$x = @'
"
Easy as
One
$b
Three
!
"
'@
$x produces:
"
Easy as
One
$b
Three
!
"
|
In single here-strings, variable names are not expanded and escape sequences are not interpreted. A single here-string begins with @' and ends with '@. PowerShell here-strings are similar to here-documents in Perl. |
Double here-strings:
$b="Two"
$x = @"
"
Easy as
One
Two
Three
!
"
"@
$x produces:
"
Easy as
One
Two
Three
!
"
|
Inside double here-strings, variable names are replaced with their values and PowerShell escape sequences are interpreted. A double here-string begins with @" and ends with "@. PowerShell here-strings are similar to here-documents in Perl. |
