first_file and second_file are the files to compare
result_file is the name of the result file
/i=UserName is the user name for a multiuser configuration

options are explained below:

Option	Description
/=Alias	Allows you to change the visible file name. Example: wincmp3.exe file1.txt /=Old file2.txt /=New
/1	Use single instance. If specified, Compare It! will find an already running instance of itself and pass the new parameters to that instance, instead of opening an additional window.

Additional Printing and Report Generation Options

Several additional options are available for both printing and report generation. These options can be specified as follows: /P:N2

The following printing/reporting options are available:

The number at the end of the command means "print changes only" with the specified number of context lines.

To select a report file, you must specify it after the /G option, as shown in the following example.

This command will generate a comparison report to c:\report.htm, including statistics and line numbers, and only 3 context lines around the differences blocks.

Selecting printer to use

When printing with command line, you can also choose which printer to use. To specify printer name, place it just after /P command:

wincmp3.exe file1.dat file2.dat /P:CN3 "My Printer Name"
