Pretty much in the title. I have a box with very little disk space left and lots of data. I want to add all of the files into a tar, deleting them as I go because there is clearly not enough space to get it all in without deleting the data. So, using the tar --remove-files option should work, if it deletes after it adds each file, not deleting after it completes the entire archive.

It's not sensitive data, just movies and music so I decided to run it anyway, so I'll find out in a while, but if anyone knows, it will certainly set my mind at ease if they could answer. If not, I'll post my findings once it's completed or failed miserably.

Since you have it running now, you can just monitor disk space or ls some files to see if they're still there. –  Stefan Seidel Sep 17 '12 at 11:35

I'm having a similar problem so I tried doing strace on tar remove-files acting on 2 files. In this case it seems like unlink is called by the system in the end, so that would mean that tar is first archiving and then deleting. This is of course not a conclusive test, but at least a hint. You could try the same thing but with more files and look if tar acts differently in that case.
