      install tldr and then you have easier commands

      > tldr dd
      
        dd
      
        Convert and copy a file.
        See also: `caligula`.

        - Make a bootable USB drive from an isohybrid file (such as archlinux-xxx.iso) and show the progress:
          sudo dd if=path/to/file.iso of=/dev/usb_drive status=progress
      
        - Clone a drive to another drive with 4 MiB block size and flush writes before the command terminates:
          sudo dd bs=4M conv=fsync if=/dev/source_drive of=/dev/dest_drive
      
        - Generate a file with a specific number of random bytes by using kernel random driver:
          dd bs=100 count=1 if=/dev/urandom of=path/to/random_file
      
        - Benchmark the write performance of a disk:
          dd bs=1M count=1024 if=/dev/zero of=path/to/file_1GB
      
        - Create a system backup, save it into an IMG file (can be restored later by swapping if and of), and show the progress:
          sudo dd if=/dev/drive_device of=path/to/file.img status=progress
      
        - Check the progress of an ongoing dd operation (run this command from another shell):
          progress

          I feel like it’s a nice intermediate step when learning the commands. man is great when you already know you have the right tool and you just need to check a flag. A newbie who just left Windows is gonna be so overwhelmed by a lot of manpages, but this does a nice job of easing them in using examples to give the user an idea of what that tool is capable of.
