Aber da sind auch ein Haufen Nullen drin. Wirklich viel steht da nicht drin:
"The * indicates that all of the lines from 00000330 to 00000400 inclusive would be the same value as the 00000330 line and that keeps the output condensed for large files with long and aligned repeating sequences. "
Default block size bei tar ist 20. D.h. die Daten werden in 20*512 Byte großen Blöcken geschrieben. Nicht vorhandene Daten werden mit NULL aufgefüllt. Du kannst ja mal mit der -b bzw. --record-size Option spielen. Christian -- Hilfe!
