Create dummy file on freebsd

dd if=/dev/random of=test bs=1m count=2

dd if=/dev/urandom of=test bs=1m count=2

(thanks simon!)

This will create 2.0M file called “test”.

[root@bentley ~]# ls -alh test
-rw-r--r--  1 root  wheel   2.0M Jun  4 15:20 test
[root@bentley ~]#

This also works on linux, but he doesn’t understand “m” as unit.

    I’m affraid /dev/random will be very slow for creating large files or benchmarking.

    /dev/urandom is the choice to go with.
