I need to shred files, but there are too many files and
shred takes ages for each file.
Each file is 4GB.
Is there a faster tool than
shred -n 1?
shred -n 1 on a 4GB file takes MORE time than copying a 4GB file to the disk.
For the same 4GB file:
shred -z -n 1: 6 minutes
shred -n 1: 4 minutes
- copy 4GB file: 3 minutes
Should I copy a 4GB file to each file? Anything smarter?
