How to burn iso file to usb sticker

1. Type command $ diskutil list to list both external/internal disks, whole disks and partitions, the result should be something like below:

    $ diskutil list
    /dev/disk0 (internal):
       #:                       TYPE NAME                    SIZE       IDENTIFIER
       0:      GUID_partition_scheme                         251.0 GB   disk0
       1:                        EFI EFI                     314.6 MB   disk0s1
       2:                 Apple_APFS Container disk1         250.7 GB   disk0s2
   
    /dev/disk1 (synthesized):
       #:                       TYPE NAME                    SIZE       IDENTIFIER
       0:      APFS Container Scheme -                      +250.7 GB   disk1
                                     Physical Store disk0s2
       1:                APFS Volume Macintosh HD            193.9 GB   disk1s1
       2:                APFS Volume Preboot                 18.6 MB    disk1s2
       3:                APFS Volume Recovery                506.6 MB   disk1s3
       4:                APFS Volume VM                      3.2 GB     disk1s4
   
    /dev/disk2 (external, physical):
       #:                       TYPE NAME                    SIZE       IDENTIFIER
       0:      GUID_partition_scheme                        *7.8 GB     disk2
       1:                        EFI EFI                     209.7 MB   disk2s1
       2:                  Apple_HFS alba                    7.4 GB     disk2s2
   

2. Unmonut the target volumn using the following command sudo diskutil umount /dev/(IDENTIFIER) disk2s2 in my case

3. You are now ready to format the usb sticker and burn iso file in to USB volumn: sudo dd if=/path/image.iso of=/dev/r(IDENTIFIER) bs=1m, if the image is compressed, an example will be unxz -c $compressed.img.xz | dd of=/dev/r(IDENTIFIER)

Note: have the r(raw) before the identifier just speedup the process, totally optional. There is no percentage of the prograss, but you can type ctrl + T to view the status at any point.
