So you have whole load of conditional statement like these:Operator | Definition |
-lt | Less than |
-le | Less than or equal to |
-gt | Greater than |
-ge | Greater than or equal to |
-eq | Equal to. If the left hand side of the operator is an array and the right hand side is a scalar, the equivalent values of the left hand side will be returned |
-ne | Not Equal to. If the left hand side of the operator is an array and the right hand side is a scalar, the not equivalent values of the left hand side will be returned |
-contains | Determine elements in a group, this always returns Boolean $True or $False. |
-notcontains | Determine excluded elements in a group, this always returns Boolean $True or $False. |
-like | Like - uses wildcards for pattern matching |
-notlike | Not Like - uses wildcards for pattern matching |
-match | Match - uses regular expressions for pattern matching |
-notmatch | Not Match - uses regular expressions for pattern matching |
-band | Bitwise AND |
-bor | Bitwise OR |
-is | Is of Type |
-isnot | Is not of Type |
These operators are the case-sensitive counterparts:
Operator | Definition |
-clt | Less than (case sensitive) |
-cle | Less than or equal to (case sensitive) |
-cgt | Greater than (case sensitive) |
-cge | Greater than or equal to (case sensitive) |
-ceq | Equal to (case sensitive) |
-cne | Not Equal to (case sensitive) |
-clike | Like (case sensitive) |
-cnotlike | Not Like (case sensitive) |
-ccontains | left hand side contains right hand side in a case sensitive manner |
-cnotcontains | determine excluded elements in a group in a case sensitive manner |
-cmatch | Match (case sensitive) |
-cnotmatch | Not Match (case sensitive) |
Other operators:Operator | Definition |
+ | Add |
- | Subtract |
* | Multiply |
/ | Divide |
% | Modulo |
-not | logical not |
! | logical not |
-band | binary and |
-bor | binary or |
-bnot | binary not |
-replace | Replace (e.g. "abcde" –replace "b","B") (case insensitive) |
-ireplace | Case-insensitive replace (e.g. "abcde" –ireplace "B","3") |
-creplace | Case-sensitive replace (e.g. "abcde" –creplace "B","3") |
-and | AND (e.g. ($a -ge 5 -AND $a -le 15) ) |
-or | OR (e.g. ($a –eq "A" –OR $a –eq "B") ) |
-is | IS type (e.g. $a -is [int] ) |
-isnot | IS not type (e.g. $a -isnot [int] ) |
-as | convert to type (e.g. 1 -as [string] treats 1 as a string ) |
.. | Range operator (e.g. foreach ($i in 1..10) {$i } ) |
& | call operator (e.g. $a = "Get-ChildItem" &$a executes Get-ChildItem) |
. (dot followed by a space) | call operator (e.g. $a = "Get-ChildItem" . $a executes Get-ChildItem in the current scope) |
-F | Format operator (e.g. foreach ($p in Get-Process) { "{0,-15} has {1,6} handles" –F $p.processname,$p.Handlecount } ) |
