Getting output of command executed through Execute Terminal Comm
No, you'll always see the entire "screen scrape" basically. TEO is just acting like a SSH/telnet client so just like when you type in a command at the screen, you see the full screen, so does TEO.
Basically, it types the command, hits enter, and then looks to make a match from the expect templates you have defined.
I have done lots of process authoring with the terminal adapter and the best way to get information out of a command line output is using the "match regular expression" activity or using some of the string activities. (find string, etc)
