I have script which works fine when I remove special character - from script, but the device send alert with -. I need to skip - in my powershell to proceed with running the script successfully.

PowerShell.Exe -File C:\abcd.ps1 RAISED Interface Status Alert: interface8 - Ethernet0 - Gi0 is Up

C:\Users\>PowerShell.Exe -File C:\abcd.ps1 RAISED Interface Status Alert: interface8 - Ethernet0 - Gi0 is Up at 11:53:10
