comparing two files (command prompt) - win2k

[bobert180]

I'm trying to create a .cmd file which i've completed except one little bit

I have a file downloaded automatically, I want to compare this to a file i already have. If the new file is different to the old file then to do some other commands (already written).When I mean the files are different i mean in terms of file size.

If anyone can help i'm looking for a way to compare newfile.exe to oldfile.exe

then return a boolean (true/false) so I can use that in an if statement

e.g.

if (oldfile.exe is different to newfile.exe)

do some commands

endif

I'm not sure how you can compare two files and return a boolean (true/false) so I can do my if statement.

thanks Rob

Some basic programming code would be your best bet. As in Visual Basic, Visual C++, or maybe even QBasic. I'm not aware of a DOS command that runs a size compare...or even gets and stores the file's sizes in RAM for comparison then Prints it on screen.

You may use Beyond Compare which allows scripting (marvelous software )
