| Post subject: | how does "delete slowly" function behind the scene |
I've got "delete files slowly" enabled in my KM box. How is the slow delete being accomplished? Is it a command line switch that is part of the "rm" command or is this something that Mythtv is doing/managing on it's own? What are the inner workings of the slow delete process? I wonder if a slow delete can be done from a command line. Such as: Code: # rm /myth/video/file.mpg" -slow

MythTV has code to do it. There is no magical 'rm' option. |

Doing a quick search on google I found this snippet (not sure about the validity): Quote: ...Delete the files in Myth, which uses a "delete slowly" function
