Description
I am using the new coreutils on ubuntu 25.10.
When executing du without options, the output format is different:
❯ du /home/mahae/yocto/gatewayng/build/tmp/work/ucm_imx8m_mini-poky-linux/core-image-base/1.0/tmp-wic/boot.2
20K /home/mahae/yocto/gatewayng/build/tmp/work/ucm_imx8m_mini-poky-linux/core-image-base/1.0/tmp-wic/boot.2/overlays
20M /home/mahae/yocto/gatewayng/build/tmp/work/ucm_imx8m_mini-poky-linux/core-image-base/1.0/tmp-wic/boot.2
❯ gnudu /home/mahae/yocto/gatewayng/build/tmp/work/ucm_imx8m_mini-poky-linux/core-image-base/1.0/tmp-wic/boot.2
20 /home/mahae/yocto/gatewayng/build/tmp/work/ucm_imx8m_mini-poky-linux/core-image-base/1.0/tmp-wic/boot.2/overlays
19804 /home/mahae/yocto/gatewayng/build/tmp/work/ucm_imx8m_mini-poky-linux/core-image-base/1.0/tmp-wic/boot.2_
When the option -k is used, an error is printed. The gnu versions accepts this option:
❯ du -bks /home/mahae/yocto/gatewayng/build/tmp/work/ucm_imx8m_mini-poky-linux/core-image-base/1.0/tmp-wic/boot.2
error: the argument '-k' cannot be used multiple times
For more information, try '--help'.
❯ gnudu -bks /home/mahae/yocto/gatewayng/build/tmp/work/ucm_imx8m_mini-poky-linux/core-image-base/1.0/tmp-wic/boot.2
19796 /home/mahae/yocto/gatewayng/build/tmp/work/ucm_imx8m_mini-poky-linux/core-image-base/1.0/tmp-wic/boot.2

Research direction
Start by reproducing the reported du and GNU du commands, including the default output and -bks combination. Compare the du command's behavior with GNU compatibility expectations; done means matching the shown GNU output format and accepting -bks without the duplicate-option error.
