Hi Yary,

Thank you!

I can't figure out

1) where it is getting its path from

2) why it looks so weird

-T

C:\NtUtil>perl6 -e "my $proc=run( dir ); say $proc.exitcode;"

C:\NtUtil>echo. 
1>>C:\ProgramData\IperiusBackup\Logs\Job001\LogFile.txt

C:\NtUtil>echo 12345 
1>>C:\ProgramData\IperiusBackup\Logs\Job001\LogFile.txt
0


C:\NtUtil>perl6 -e "my $proc=run( dir 'c:\NtUtil' ); say $proc.exitcode;"

C:\NtUtil>echo. 
1>>C:\ProgramData\IperiusBackup\Logs\Job001\LogFile.txt

C:\NtUtil>echo 12345 
1>>C:\ProgramData\IperiusBackup\Logs\Job001\LogFile.txt
