PowerShell: Operators
@(…) is the
array subexpression operator: it creates an
array from the expression within its parentheses, regardless if the expression evaluates to 0, 1 or more elements.
, with two variants (unary and binaray), both of which create
arrays .
-not (two variants:
logical and bitwise)
Arithmetic operators:
+,
- *,
/,
%,
++,
--,
+=,
-=,
*=,
/=,
-shl,
-shr,
-band,
-bnot,
-bor,
-xor
The
-as operator
casts a value into a different type.
A value can also be cast by prepending a type before it: [int]0x40.
range operator . It creates an unconstrained one dimensional
array . (see also
..)
The format operator (
-f) formats strings.
-in and
-notIn check if a value is (not) present in a collection.
assignment
PowerShell 7 also has the
ternary operator (
$cond ? doSomething : doAnotherThing )
Order of precedence
$() / @() / () . Member access operator :: Static operator […] Index operator [datatype ] cast operator -split Split operator (This is a unary operator and has higher precedence than the binary split operator) -join Join operator (This is a unary operator and has higher precedence than the binary join operator) , Comma operator ++ / -- Increment and decrement (These operators are considered assignment operators , but have higher precedence than for example =, see below) ! / -not Logical operators .. Range operator -f Format operator - Unary (negative) operator * / / / % + / - -split / -join / -is / -isNot / -as-eq/ -ne / -ne / -gt / -gt / -lt / -le / -like-notLike-match-notMatch-in-notIn / -contains / -notContains / -replace The -split and -join operator with this precedence are binary opeators. There is also a unary version that has higher precedence. -band / -bnot / -bor / -bxor / -shl / shr Bitwise operators -and / -or -xor . Dot source operator & Call operator | Pipeline operator > / >> / 2> / 2>> / 2>&1 Redirection operators = / += / -= *= / /= / %= Assignment, compare with ++ and --
Setting the color used for operators
PowerShell allows to define a color that is used for operators when using an interactive shell:
set-psReadLineOption -colors @{
operator =
"$([char]27)[38;2;255;127;0m" + # forground color: orange
"$([char]27)[48;2;100;120;130m" # background color: grey
}
