      @johnhooks So, you just use

      pv dd if=/dev/urandom of=/dev/sda bs=512k
      

      That's actually really handy.

      YOu have to pipe it in, it's a strange syntax

      dd if=/dev/zero | pv | dd of=/dev/sda
      

      Also any flags or arguments go before the first pipe.

        Very odd indeed.

          That is a bit odd. Still handy tho.

              My favourite linux command is "ls"
              "cd"

                  I use them all the time, doesn't mean I like them. At least ls is shorter than dir.

                    This is also helpful, diff is confusing unless you use some flags.

                    diff -y -W 70 file file2
                    

                    It makes viewing changes much easier. Below is a screenshot. The pipe shows there is a difference in the line, and the < or > show that there is a line added or subtracted.

                      I always end up typing dir on my linux machines and ls on my windows machines.... it just frustrates me...

                            This thread deserves more attention than it gets. I was getting annoyed with dd and no status display today (lots of Raspberry Pis to image.) This time I know the exact size of the sd cards being imaged tho, so pv is very helpful.

                            dd if=/home/comtech/rpi.img | pv -s 16g | dd of=/dev/mmcblk0 bs=4k

                            [root@localhost comtech]# dd if=/home/comtech/rpi.img | pv -s 16g | dd of=/dev/mmcblk0

                              This isn't installed by default on some systems, but i easy & quick to add.

                                  When I want to use virt-manager from my Mac.

                                  ssh -Y username@ip-address
                                  virt-manager &
