I have the following batch script:

set logFile=%1_%time:~0,2%_%time:~3,2%.log

set logFile=%logFile: =%

Does anyone know what the second line is all about?

It says replace all spaces with nothing. If logfile was "This Is a Test" then after the second line, it would be "ThisIsaTest" (spaces equal nothing)

MultiverseIT described what's going on. For more detail on environment variable substitution, look at the help for the SET command

Set /?

on the command line
