How to export difference into another text file by command line?

[lasthero]

Dears,

I purchased BC3 few hours ago, now I have a problem on command line mode, here is my batch file to auto compare two text files:

bcomp.exe A.txt B.txt /qc

But I want to export the difference to C.txt if the error level code=13, so I need to know what commands to finish my request, please help me.

PS: I don't need the UI so I use /qc command.

Thanks,
Jacky

Hello,

/qc only supports the error level output. For generating a report, you will need to use BC Scripting, as documented in the Help file -> Using Beyond Compare -> Automating with Script chapter.

The rough command line you are looking for is:
bcompare.exe "@c:\bcscript.txt" "c:\A.txt" "c:\B.txt" "c:\report.txt"

where bcscript.txt is:
text-report layout:side-by-side options:display-mismatches output-to:"%3" "%1" "%2"
