We recently migrated to IRIS. Before, the CACHE.EXE executable could be invoked from a batch file directly :  > C:\InterSystems\Cache\bin\cache.exe -s C:\InterSystems\Cache\mgr -U %SYS This will display the following in console :  > Node: DESKTOP-8H4B321, Instance: CACHE > > USER> Additionally, the pipe instruction can be used to redirect some commands directly > echo write 50 | C:\InterSystems\Cache\bin\cache.exe -s C:\InterSystems\Cache\mgr -U %SYS I am looking for the same thing in IRIS. If I do the same command line with IRIS executable, I got an error :  > Invalid argument to IRIS : -s I have looked into documentation and the following can be used but it's not the equivalent : > IRIS.exe run IRIS > IRIS.exe console IRIS > IRIS.exe terminal IRIS EDIT : I found a similar question [here](https://community.intersystems.com/post/wanted-irissession-windows)
