Re: Bug in rm -r with locked files

Hi,

This is a bug report about rm (package fileutils, version 4.1-1) on W2K.

Test case: take 2 cygwin shells.
shell 1:
mkdir /tmp/directory
vi /tmp/directory/file

shell 2:
/bin/rm -rf /tmp/directory

The shell2 doesn't manage to remove the directory and goes into an infinite loop, taking 100% of the CPU.
All is then OK if we go out of vi in the shell1.

Doing the same thing (deleting the directory) directly in Windows produces an error message: "cannot delete directory: Access is denied. The source file may be in use" and we can notice in the directory a file named .file.swp that is also visible under Cygwin with ls -la.

The example I have just given uses vi, but it is the same with all processes that open the file, as W2K puts a lock on it.

OK. If I summurize all that has been said, this problem is well-known but has no solution in a near future.

But a workaround would be very useful for people (me and Brian Kelly, for instance) who use plenty of rm -rf in cross-platform shell scripts.

Thanks to Shankar Unni, I have mine: I didn't noticed that only rm -rf had the trouble, and not rm -r.

So my workaround will be to replace all the '/bin/rm -rf dir' by 'chmod -R +w dir; /bin/rm -r dir'. The semantic is not exactly the same (especially on write-protected directories), but that will allow my scripts to work well...

Thanks everybody.

Gael.
