Batch file log output append

Resulting in only the LAST file of that first directory being in the log I'm not trying to shoot at you.

This demonstrates the point the OP was making. June 14, at am I am trying to run a batch file which runs an executable and redirects its output to a log file. The log file must have the date and time as the file name. This is the command I am using:. This command works when pasted directly in cmd.

However, it does not work when pasted in a batch file, and then run in cmd. Cmd interprets the command as follow:. Notice how the file name is truncated and the time is now appended to the command arguments instead of being in the file name. So obviously the command fails.

I explained why batch can't do it, and offered some ideas that would do it, and gave some batch code that actually works. You're suggesting to redirect nothing into an environment variable which doesn't make sense. Sorry i din't know i had to specify every little bit.
