Try Catch on executable exe in Powershell?

> try / catch in PowerShell doesn't work with native executables.

Actually it does, but only if you use "$ErrorActionPreference = 'Stop'" AND append "2>&1".

See "Handling Native Commands" / Tobias Weltner at https://community.idera.com/database-tools/powershell/powertips/b/ebookv2/posts/chapter-11-error-handling.

E.g.

$ErrorActionPreference = 'Stop'
Try
{
    $output = C:\psftp.exe ftp.blah.com 2>&1
}
Catch
{
    echo "ERROR: "
    echo $output
    return
}
echo "DONE: "
echo $output

try / catch in PowerShell doesn't work with native executables. After you make the call to psftp.exe, check the automatic variable $LastExitCode. That will contain psftp's exit code e.g.:

$output = C:\psftp.exe ftp.blah.com 2>&1
if ($LastExitCode -ne 0)
{
    echo "ERROR: "
    echo $output
    return
}

The script above presumes that the exe returns 0 on success and non-zero otherwise. If that is not the case, adjust the if (...) condition accordingly.
