Multiple IF statements in PS

[petben]

Hello, I’m trying to achieve this in powershell, getting stuck with logic.

 

If (test path c:\1.txt) {

Do something 1}

 

If (test path c:\2.txt) {

Do something 2}

 

Else {do something 3}

 

The trouble is that it’s always running ‘do something 3’ as one of the if statements is always not satisfied. How can I get this to only run the else if neither file exists? Easy surely..

[Mr.Ben]

Would a switch statement work?

[Davit2005]

I've not had much success to get multiple if statements to work, try if then elseif then else.

 

if (test path c:\1.txt) {

Do something 1}

 

esleif (test path c:\2.txt) {

Do something 2}

 

Else {do something 3}

Based on what you said in terms of how it's outputting, it shouldn't do that even if you're using the code logic you mentioned.

 

As if C:\1.txt exists it'll run 1 (and then 3 as 2 doesn't) - Still not what you want I know, but the code you're using will make a difference to how this acts

If C:\2.txt exists it'll run 2 only (Not 3 as 1 doesn't check for 3)

 

So unless you're trying to do something like assigning it to a variable using T/F and assigning it wrong so it always calculates 3 anyway

 

As Davit said above, using else/if should work, but I'd still be curious to see your original code as it shouldn't be possible to get 3 from both outcomes either way in your current logic

 

If (Test-Path C:\1.txt) {
Write-Host "1"
}
ElseIf (Test-Path C:\2.txt) {
Write-Host "2"
}
Else {
Write-Host "3"
}

Another thought that as the actual paths are a file in either

Program files

Or

Program files (x86)

 

I could just use a Wild card in the test-path command?

If (test-path ‘C:\program files*’)

 

Much easier?

[petben]

last thing

 

with the wildcard in place I need to put a get-item so there's an actual file path to work with later on

 

$FilePath =

Get-Item

"‘C:\program files*\1.txt"

$DesiredVersion = '999.999'

 

then I get the version of the file

 

# Get the version from the computer

If(Test-Path $FilePath) {

$Version = [system.diagnostics.fileversioninfo]::GetVersionInfo($FilePath).FileVersionRaw

} else {

# File not found, set version to 0

$Version = '0.0.0.0'

}

 

 

but it it now not setting $Version = '0.0.0.0' if the path is not found, it just errors with

 

"Cannot bind argument to parameter 'Path' because it is null"

 

 

a minor tweak required, can anyone advise?

I was having similar issues on Powershell, so swapped to a switch statement.. For example. The default is the catch all that runs if none of the previous lines apply.

 

SWITCH ( $RESULT){ test path c:\1.txt { Do something 1 } test path c:\2.txt { Do something 2 } default { Do something 3 }}

Can you definitely use Test-path in that way?

 

It works on folder paths, not sure about files.
