  • 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
    
    








  • Already before the LLMs for me it was the last chance before I would post over there. The desperation move. It was too toxic and I would always get pissed to get my question closed because too similar or too easy or whatever. Hey I wasted 15 minutes to type that, if the other question solved the problem I wouldn’t post again…

    In the beginning it wasn’t like that…

    I went to watch my stack overflow account and the first questions that I posted (and that gave me 2000 karma) would have been almost all of them rejected and removed
