I know I can tell Excel to open a file with:
open MAC\ Addresses.xlsx -a "Microsoft Excel.app/"
But I cannot figure out how to do anything with Excel from the terminal.
Where can I find a list of the commands that can be sent to Excel from the terminal?
/Applications/Microsoft\ Excel.app/Contents/MacOS/Microsoft\ Excel --help
?arp -a
in a form useable by Excel, how can I launch Excel from Terminal with this and how can I send commands from Terminal to Excel. So can you edit your question to focus on the main objective here?
