The 'part uuid' command prints or sets an environment variable to partition UUID interface interface for accessing the block device (mmc, sata, scsi, usb, ....) dev device number part partition number varname an optional environment variable to store the current partition UUID value into. The 'part list' command prints or sets an environment variable to the list of partitions interface interface for accessing the block device (mmc, sata, scsi, usb, ....) dev device number part partition number flags -bootable lists only bootable partitions varname an optional environment variable to store the list of partitions value into. The 'part start' commnad sets an environment variable to the start of the partition (in blocks), part can be either partition number or partition name. interface interface for accessing the block device (mmc, sata, scsi, usb, ....) dev device number part partition number varname a variable to store the current start of the partition value into. The 'part size' command sets an environment variable to the size of the partition (in blocks), part can be either partition number or partition name. interface interface for accessing the block device (mmc, sata, scsi, usb, ....) dev device number part partition number varname a variable to store the current size of the partition value into. The 'part number' command sets an environment variable to the partition number using the partition name, part must be specified as partition name. interface interface for accessing the block device (mmc, sata, scsi, usb, ....) dev device number part partition number varname a variable to store the current partition number value into The 'part type' command prints or sets an environment variable to the partition type UUID. interface interface for accessing the block device (mmc, sata, scsi, usb, ....) dev device number part partition number varname a variable to store the current partition type UUID value into The 'part types' command list supported partition table types.

If an error occurs, the return value $? is set to 1 (false). |
