Helpful Dtexec.exe cheats:

To execute an SSIS package saved to SQL Server using Windows Authentication:
dtexec /sq pkgOne /ser productionServer

To execute an SSIS package saved to the File System folder in the SSIS Package Store:
dtexec /dts "\File System\MyPackage"

To validate a package that uses Windows Authentication and is saved in SQL Server without executing the package:
dtexec /sq pkgOne /ser productionServer /va

To execute an SSIS package that is saved in the file system:
dtexec /f "c:\pkgOne.dtsx"

To execute an SSIS package that is saved in the file system, and specify logging options:
dtexec /f "c:\pkgOne.dtsx" /l "DTS.LogProviderTextFile;c:\log.txt"

To execute a package that uses Windows Authentication and is saved to the default local instance of SQL Server, and verify the version before it is executed:
dtexec /sq pkgOne /verifyv {c200e360-38c5-11c5-11ce-ae62-08002b2b79ef}

To execute an SSIS package that is saved in the file system and configured externally:
dtexec /f "c:\pkgOne.dtsx" /conf "c:\pkgOneConfig.cfg"
