A self destruct command in a .bat file:

del %0.bat

works, but gives an error message "Batch file missing."

To suppress the error message, edit the .bat file, remove all trailing
CRLFs, and put CTRL-Z (EOF) immediately following the command. Hex dump
looks like this:

64 65 6c 20 25 30 2e 62 61 74 1a del %0.bat.

The "1a" character is CTRL-Z.

Why self destruct a .bat file? That's another topic.

But only if you start the batch with "filename" and not "filename.bat".
And even then only, if the name is "filename.bat" and not "filename.cmd"

Isn't it simpler to use:

del %0.bat &exit

This not even has to be the last line in the batch file.

This is MS-DOS, not Windows dos box. Take your Windows baggage and go.
