Quick mirror in batch file

[AndrewStein]

I'd like to be able to have a series of commands in a batch file that simply passed two directory names to beyond compare and the result would be a mirror of one to the other.

I think I can do this using scripting but I don't know how to do this without having a special script for each action.

You can use %1 through %9 to refer to command line arguments within the scripts. The values don't include the script name (@script) or any switches (/silent). So you could have a script like:

load "%1" "%2"
sync mirror:lt->rt

And then call it like:
BCompare.exe @script C:\Dir1 C:\Dir2

You could also pass the sync type in as an argument, and call it like:
BCompare.exe @script mirror C:\dir1 C:\dir2.
