partprobe [OPTIONS] [device...]
DESCRIPTION
partprobe informs the operating system kernel of partition table changes. After modifying partitions using fdisk, parted, or similar tools, partprobe updates the kernel's partition table without requiring a reboot.
PARAMETERS
-d, --dry-run
Don't actually inform the kernel, just print what would be done-s, --summary

CAVEATS
Cannot update partitions that are in use or mounted. The kernel may refuse to update the partition table if any partition on the device is busy. In such cases, a reboot may be required.
HISTORY
partprobe is part of the parted package, providing partition table synchronization with the kernel.
