The following command line options are available when running HL7Spy:

HL7Spy.exe [-e] [-lf=file(s)] [-mllp=port]

-?|help|h - Prints out the options.
-e (Use Existing): use an existing HL7Spy instance, don't start a new one
-ca|CloseAll - close existing tabs. Only useful with the -e option
-lf (Load File(s)): file(s) - Each -lf call results in a single tab. Multiple files to be placed in a single tab can be separated with a ; (semicolon) 
-mllp (Start MLLP Listener): port - integer port to listen on
-compare: Run the Bulk Compare tool on the last 2 tabs loaded

Note: Option names are case insensitive

Example - Load the file c:\temp\file.hl7 into a currently running instance of HL7Spy:
HL7Spy -e -lf="c:\Temp\file.hl7"

Example - Load 2 tabs with the first tab containing file1.hl7 and file2.hl7 and the second tab containing file3.hl7 and file4.hl7. Close any existing tabs first:
