Powershell script to check if a file exists on remote computer list

Question

I'm new at Powershell, and I'm trying to write a script that checks if a file exists; if it does, it checks if a process is running. I know there are much better ways to write this, but can anyone please give me an idea? Here's what I have: ``` Get-Content C:	emp\SvcHosts\MaquinasEstag.txt | ` Select-Object @{Name='ComputerName';Expression={$_}},@{Name='SvcHosts Installed';Expression={ Test-Path "\$_\c$\Windows\svchosts"}} if(Test-Path "\$_\c$\Windows\svchosts" eq "True") { Get-Content C:	emp\SvcHosts\MaquinasEstag.txt | ` Select-Object @{Name='ComputerName';Expression={$_}},@{Name='SvcHosts Running';Expression={ Get-Process svchosts}} } ``` The first part (check if the file exists, runs with no problem. But I have an exception when checking if the process is running: ``` Test-Path : A positional parameter cannot be found that accepts argument 'eq'. At C:	emp\SvcHosts\TestPath Remote Computer.ps1:4 char:7 + if(Test-Path "\$_\c$\Windows\svchosts" eq "True") + ~~~~~~~~~~~~~~~~~~~~…

Accepted Answer

The equality comparison operator is `-eq`, not `eq`. The boolean value "true" in PowerShell is `$true`. And if you want to compare the result of `Test-Path` to something the way you do, you must run the cmdlet in a subexpression, otherwise `-eq "True"` would be treated as an additional option `eq` with the argument `"True"` to the cmdlet.

Change this:

```
if(Test-Path "\$_\c$\Windows\svchosts" eq "True")
```

into this:

```
if ( (Test-Path "\$_\c$\Windows\svchosts") -eq $true )
```

Or (better yet), since `Test-Path` already returns a boolean value, simply do this:

```
if (Test-Path "\$_\c$\Windows\svchosts")
```
