Linux – How to create tar archive split into, or spanning, multiple files


According to this page, one can let tar create a tar archive "split" into 100 Mb files:

tar -c -M –tape-length=102400 –file=disk1.tar largefile.tgz

The problem is that this command will require you to interactively give a new filename for the next file, after the first file is filled.

Anybody knows of a way to skip this interactive step, and let tar do the "splitting" automatically?

Best Answer

Take a look at the --new-volume-script option, which lets you replace the prompting mechanism with a different mechanism or with a generated filename. (( Archives in the tar info page.) The problem with split is that you need to cat the pieces back together to do anything, whereas a multivolume archive should be a bit more flexible.
