My Powershell script is throwing an exception, but not giving me the line number where the exception is thrown:
The process cannot access the file 'C:/path/to/foo.txt' because it is being used by another process.
+ CategoryInfo : NotSpecified: (:) [Set-Content], IOException
+ FullyQualifiedErrorId : System.IO.IOException,Microsoft.PowerShell.Commands.SetContentCommand
+ PSComputerName : localhost
I would think the best practice here is to refactor the script to use try/catch blocks to narrow down exactly where the Set-Content exception is being thrown - but in this case, due to the size/scope of the script, I am trying to avoid that option.
Instead, I'm hoping for a bit of a top-down solution - for instance, being able to call the script with added verbosity, in such a way that Powershell prints the line numbers in the stack traces (pretty sure Python does this by default).
Does Powershell 3.0 natively support this?
EDIT: The accepted answer to this question involves the try/catch approach, which I have mentioned is not my preferred approach. Again, is there some way to get PowerShell to report line numbers when exceptions are raised without mandatory try/catches? Would I have to wrap the entire script in a generic try/catch? Would I have to invoke the script with some --verbose flag? Does Powershell 3.0 support anything like that?
