dd
Convert and copy a file.
- Make a bootable usb drive from an isohybrid file (such like
archlinux-xxx.iso
) and show the progress:
dd if={{file.iso}} of=/dev/{{usb_drive}} status=progress
- Clone a drive to another drive with 4MB block, ignore error and show progress:
dd if=/dev/{{source_drive}} of=/dev/{{dest_drive}} bs=4M conv=noerror status=progress
- Generate a file of 100 random bytes by using kernel random driver:
dd if=/dev/urandom of={{random_file}} bs=100 count=1
- Benchmark the write performance of a disk:
dd if=/dev/zero of={{file_1GB}} bs=1024 count=1000000
- Check progress of an ongoing dd operation (Run this command from another shell):
kill -USR1 $(pgrep ^dd)
