That isn't a job for a batch program. Use a scriptable editor, PowerShell
or even C code. If it has to be done in a batch, process the input file
byte by byte: the following code skips anything including the first ":".
Then outputs the following bytes till the 5. "=" and the skips the rest
of the line. But it is extremely slow.
