How do I negate a condition in PowerShell?
If you are like me and dislike the double parenthesis, you can use a function
function not ($cm, $pm) {
if (& $cm $pm) {0} else {1}
}
if (not Test-Path C:\Code) {'it does not exist!'}
Example
You almost had it with Not
. It should be:
if (-Not (Test-Path C:\Code)) {
write "it doesn't exist!"
}
You can also use !
: if (!(Test-Path C:\Code)){}
Just for fun, you could also use bitwise exclusive or, though it's not the most readable/understandable method.
if ((test-path C:\code) -bxor 1) {write "it doesn't exist!"}
