DEL *this* file (whatever its name) in Batch File

[stephjo]

Hi DOS enthusiasts,

I've got an image analysis software that spits out batch files and often changes the content and the name(!) and the location of the batch file for various reasons. So, very often, if I have a "DEL" command at the end of the file, the command doesn't execute because I don't have the name right and/or location right.

It'd be superb if there was a way to have a command at the end of these batch files that says

del /q whatever_this_batch_file_name.bat

How do I do this?

Thank you,
-Steph

%0 is the full path of the script that is currently running.

Code: Select all

del %0

Nope. %0 contains how the script was called. Consider to have a "FOO.bat". From within a command prompt you could just enter FOO to run it. But in this case %0 expands to only FOO where deleting would fail.
To expand it to the full path you have to use "%~f0" (including the quotes to protect you from spaces and special characters).

Horrifyingly, I've spent almost the last decade tab-completing the name of the script so I've literally never run into this problem.

Thought I'd just mention (though obvious) this works while delayed expansion is disabled though if it's later enabled requires getting past endlocal and some form of escaping for characters such as exclamation points and carets (which itself can be a PITA until one finds suitable methods :p).
