This is truncated version of what the call returns - the call returns information all the way back to the start of data records in the DB system (in TIK's case back to 2009)
data.get {stn} X startDate endDate | grep {blah}
Allows you to extract message log entries into a file. {stn} is the three letter station ID, piping the command to 'grep {BLAH}' allows you to extract only message log entries with the word 'blah' in them.

Note you can do multiple pipes to grep to narrow down the extraction, for example:
data.get {stn} X startDate endDate | grep {blah1} | grep {blah2}

All the options for data.get can be used to format the output.
data.get app X 320 330 | grep USER
returns:
