It’s spelled out very clearly in Help… From the Admin client, press F1 for the Adminstrators Help File.
Then search on “Updall”. It is even full of examples. But be sure to press F1 when you are looking at the ADMIN client, not the End User client… it brings up different help files.

As a side note, you can open Help for Client, Designer, or Administrator (if you have installed them) by pressing Ctrl-O and opening the Help folder. Create bookmarks and you have quick access without opening Designer/Admin clients. -LD

We suppose it’s for Windows world !?!

If you want to run it on the server (Domino side) you have to type “load” before the command like “load compact -c” in the console (or you could use the Administrator client with GUI)

If you want to run it on the client (Notes side) you have to type the same command with “n” first , like “ncompact” or “nfixup”. Dont forger the full path to your notes installation folder, like “c:\lotus\notes\ncompact”
