I removed it using rm. I don't know what you mean.
That on Unix, a file is not actually remooved as long as there is an opened
filehandle poiinting to it. So if you remove a log while the program writing
it is still running, you can't free space. You must restart the program so
the pending filehandle is closed and the file removed (and the space freed).
Another solution is to truncate the file (see trunc(3)):
$ >file
This is very sweet of Unix.
* Why is it sensible to allow to truncate a file someone has opened?
* Especially if you don't allow to remove such files?
* Or, more specifically, you ALLOW to remove such files, but not to reclaim the
disk space?
* And how am I supposed to know which process is using the file?
For instance, Unix will let you overwrite a shared object used by a process, and
the process will crash. Isn't it *hateful*?
