Works for me:
blcli_execute DepotObject getDBKeyByTypeStringGroupAndName DEPOT_FILE_OBJECT "/All Depot Objects by User/BLAdmin" "passwd"
What is blcli_execute? I have been using blcli. I don't see a blicli_execute.bat in my bin folder. Could that be the issue?
Never mind, when I tried running it directly on the command line instead of in a shell script it worked. I think there's something going on with the shell script.
After I did dos2unix on my shell script it magically started working.
