You can have it delete itself if you can manage to call the CreateFile Win32 API function with the FILE_FLAG_DELETE_ON_CLOSE flag. At least that's what demerphq told p5p about something similar when trying to get M::B to be able to install Cwd. http://msdn.microsoft.com/library/default.asp?url=3D/library/en-us/fileio/f= s/createfile.asp Josh |

Batch files most certainly can delete themselves on NT/W2k and etc. I believe that the command processor opens the file, reads a line, does a tell, closes the file then executes the line then when control returns reopens and seeks then reads again. Suffice it to say that i tested whether a batchfile along the lines of del self.bat echo foo could succesffully self delete. Yves -- perl -Mre=3Ddebug -e "/just|another|perl|hacker/" |

That's true of binary executable images, batch scripts turn out to be different... We start with a perl script 'Build', run it through the 'pl2bat' utility which prefaces it with a batch script that invokes the perl interpreter with itself, skipping the batch header. This produces the 'Build.bat' file that we execute. Perl reads the entire file in, closing the handle. Initially, we tried deleting the 'Build.bat' from the perl side of the script. It worked: the file was unlinked. But when execution returned the shell, the batch script was no longer there, producing the "not found" error. This seems to imply that batch files are opened, read & executed one line at a time. This is important. The final solution, the one being tweaked now because of slight syntax differences between commands on 9x vs NT, involves appending DOS commands to the end of the batch script during the execution of the 'realclean' action. The general solution was suggested by some people in the alt.msdos.batch newsgroup. Basically, it's executing the following commands from a batch file: > It will need more quotes for NT, but works here. > > @echo off > start "" /min "%comspec%" /c del "%~f0" > > > For Win9x this should work > > @echo off > start /min "%comspec%" /c del "%~f0" Note the %~f0 syntax is specific to NT, but is not a problem because we fill in the literal path before appending the command to the batch script. The main syntax difference that caused the failure on 9x was from the "" as the first argument; I still don't understand that requirement. When 'Build realclean' is executed, it does it's thing deleting everything but the 'Build.bat'. It opens the 'Build.bat' for appending, adding the command above. When the perl side exits, control returns to the shell which continues execution of the now extended batch script. This works perfectly as far as I can tell; though it's a very odd way to go about it. There is a couple of other issues. Cygwin is running pl2bat; I don't know if it should, and if it is decided it should, the solution will be different under the bash shell. The other is the test failures that Dr Bean noticed; I'm not convinced yet that they are related to any of this, i.e. I wonder if they are pre-existing issues. Randy. PS: Still trying to get caught up on stuff that transpired while I was away on a very nice little vacation. Unfortunately, I also brought back a nasty little cold with me. Catching up as fast as I can, but I came back to over a thousand mails/mailing-list msgs/etc... |

(One nice use of this trick is that you can write a perl script that is then run through pl2bat which is capable of altering its parents enviornment.)

It don't work on Win9x like things. I had to read the source of the HTML to see which item the "doesn't work on Windows 9x/ME" belonged to. It was to the previous flag, not the one I mentioned. Not that it matters much since it isn't going to do the job here *anyway*..= . I just mention that it's easy to read that page and think it says the flag doesn't work on 9x/ME. The table cells aren't aligned nicely and there's no borders so you have to guess what text belongs in what row (or read the source). Josh |
