Which command produces more data per second? This could be useful to quickly fill a file with garbage data or to test data transfer rates. So far, I found that "/dev/zero" is the quickest one.
$ cat /dev/urandom | pv > /dev/null 3,04GO 0:08:22 [5,83MB/s] [ <=> ] $ yes | pv > /dev/null 38GO 0:11:56 [40,2MB/s] [ <=> ] $ cat /dev/zero | pv > /dev/null 754GO 0:08:52 [ 1,4GB/s] [ <=> ]
Would you suggest another possible faster command?
