-.Dd February 5, 2008 -.Os -.Dt GPT 8 -.Sh NAME -.Nm gpt -.Nd "GUID partition table maintenance utility" -.Sh SYNOPSIS -.Nm -.Op Ar general_options -.Ar command -.Op Ar command_options -.Ar device ... -.Sh DESCRIPTION -The -.Nm -utility provides the necessary functionality to manipulate GUID partition -tables (GPTs), but see -.Sx BUGS -below for how and where functionality is missing. -The basic usage model of the -.Nm -tool follows that of the -.Xr cvs 1 -tool. -The general options are described in the following paragraph. -The remaining paragraphs describe the individual commands with their options. -Here we conclude by mentioning that a -.Ar device -is either a special file -corresponding to a disk-like device or a regular file. -The command is applied to each -.Ar device -listed on the command line. -.Ss General Options -The general options allow the user to change default settings or otherwise -change the behaviour that is applicable to all commands. -Not all commands use all default settings, so some general options may not -have an effect on all commands. -.Pp -The -.Fl p Ar count -option allows the user to change the number of partitions the GPT can -accomodate. -This is used whenever a new GPT is created. -By default, the -.Nm -utility will create space for 128 partitions (or 32 sectors of 512 bytes). -.Pp -The -.Fl r -option causes the -.Nm -utility to open the device for reading only. -Currently this option is primarily useful for the -.Ic show -command, but the intent -is to use it to implement dry-run behaviour. -.Pp -The -.Fl v -option controls the verbosity level. -The level increases with every occurrence of this option. -There is no formalized definition of the different levels yet. -.Ss Commands -.Bl -tag -width indent -.\" ==== add ==== -.It Xo -.Nm -.Ic add -.Op Fl b Ar number -.Op Fl i Ar index -.Op Fl s Ar count -.Op Fl t Ar type -.Ar device ... -.Xc -The -.Ic add -command allows the user to add a new partition to an existing table. -By default, it will create a UFS partition covering the first available block -of an unused disk space. -The command-specific options can be used to control this behaviour. -.Pp -The -.Fl b Ar number -option allows the user to specify the starting (beginning) sector number of -the partition. -The minimum sector number is 1, but has to fall inside an unused region of -disk space that is covered by the GPT. -.Pp -The -.Fl i Ar index -option allows the user to specify which (free) entry in the GPT table is to -be used for the new partition. -By default, the first free entry is selected. -.Pp -The -.Fl s Ar count -option allows the user to specify the size of the partition in sectors. -The minimum size is 1. -.Pp -The -.Fl t Ar type -option allows the user to specify the partition type. -The type is given as an UUID, but -.Nm -accepts -.Cm boot , efi , swap , ufs , zfs , hfs , linux -and -.Cm windows -as aliases for the most commonly used partition types. -.\" ==== boot ==== -.It Xo -.Nm -.Ic boot -.Op Fl b Ar pmbr -.Op Fl g Ar gptboot -.Op Fl s Ar count -.Ar device ... -.Xc -The -.Ic boot -command allows the user to make a GPT labeled disk bootable via the BIOS -bootstrap on i386 and amd64 machines. -By default, -the -.Pa /boot/pmbr -boot loader is installed into the PMBR and the -.Pa /boot/gptboot -boot loader is installed into the first boot partition. -If no boot partition exists and there is available space, -a boot partition will be created. -.Pp -The -.Fl b Ar pmbr -option allows the user to specify an alternate path for the PMBR boot loader. -.Pp -The -.Fl g Ar gptboot -option allows the user to specify an alternate path for the GPT boot loader -that is installed into the boot partition. -.Pp -The -.Fl s Ar count -option allows the user to specify the size in sectors of the boot partition -if one does not already exist. -A boot partition must be at least 16 kilobytes. -By default, -a size of 64 kilobytes is used. -Note that the PMBR boot loader will load the entire boot partition into -memory. -As a result, the boot partition may not exceed 545 kilobytes. -.\" ==== create ==== -.It Nm Ic create Oo Fl fp Oc Ar device ... -The -.Ic create -command allows the user to create a new (empty) GPT. -By default, one cannot create a GPT when the device contains a MBR, -however this can be overridden with the -.Fl f -option. -If the -.Fl f -option is specified, an existing MBR is destroyed and any partitions -described by the MBR are lost. -.Pp -The -.Fl p -option tells -.Nm -to create only the primary table and not the backup table. -This option is only useful for debugging and should not be used otherwise. -.\" ==== destroy ==== -.It Nm Ic destroy Oo Fl r Oc Ar device ... -The -.Ic destroy -command allows the user to destroy an existing, possibly not empty GPT. -.Pp -The -.Fl r -option instructs -.Nm -to destroy the table in a way that it can be recovered. -.\" ==== label ==== -.It Xo -.Nm -.Ic label -.Op Fl a -.Aq Fl f Ar file | Fl l Ar label -.Ar device ... -.Xc -.It Xo -.Nm -.Ic label -.Op Fl b Ar number -.Op Fl i Ar index -.Op Fl s Ar count -.Op Fl t Ar type -.Aq Fl f Ar file | Fl l Ar label -.Ar device ... -.Xc -The -.Ic label -command allows the user to label any partitions that match the selection. -At least one of the following selection options must be specified. -.Pp -The -.Fl a -option specifies that all partitions should be labeled. -It is mutually exclusive with all other selection options. -.Pp -The -.Fl b Ar number -option selects the partition that starts at the given block number. -.Pp -The -.Fl i Ar index -option selects the partition with the given partition number. -.Pp -The -.Fl s Ar count -option selects all partitions that have the given size. -This can cause multiple partitions to be removed. -.Pp -The -.Fl t Ar type -option selects all partitions that have the given type. -The type is given as an UUID or by the aliases that the -.Ic add -command accepts. -This can cause multiple partitions to be removed. -.Pp -The -.Fl f Ar file -or -.Fl l Ar label -options specify the new label to be assigned to the selected partitions. -The -.Fl f Ar file -option is used to read the label from the specified file. -Only the first line is read from the file and the trailing newline -character is stripped. -If the file name is the dash or minus sign -.Pq Fl , -the label is read from -the standard input. -The -.Fl l Ar label -option is used to specify the label in the command line. -The label is assumed to be encoded in UTF-8. -.\" ==== migrate ==== -.It Nm Ic migrate Oo Fl fs Oc Ar device ... -The -.Ic migrate -command allows the user to migrate an MBR-based disk partitioning into a -GPT-based partitioning. -By default, the MBR is not migrated when it contains partitions of an unknown -type. -This can be overridden with the -.Fl f -option. -Specifying the -.Fl f -option will cause unknown partitions to be ignored and any data in it -to be lost. -.Pp -The -.Fl s -option prevents migrating -.Bx -disk labels into GPT partitions by creating -the GPT equivalent of a slice. -.\" ==== remove ==== -.It Nm Ic remove Oo Fl a Oc Ar device ... -.It Xo -.Nm -.Ic remove -.Op Fl b Ar number -.Op Fl i Ar index -.Op Fl s Ar count -.Op Fl t Ar type -.Ar device ... -.Xc -The -.Ic remove -command allows the user to remove any and all partitions that match the -selection. -It uses the same selection options as the -.Ic label -command. -See above for a description of these options. -Partitions are removed by clearing the partition type. -No other information is changed. -.\" ==== show ==== -.It Nm Ic show Oo Fl lu Oc Ar device ... -The -.Ic show -command displays the current partitioning on the listed devices and gives -an overall view of the disk contents. -With the -.Fl l -option the GPT partition label will be displayed instead of the GPT partition -type. -The option has no effect on non-GPT partitions. -With the -.Fl u -option the GPT partition type is displayed as an UUID instead of in a -user friendly form. -The -.Fl l -option takes precedence over the -.Fl u -option. -.El -.Sh SEE ALSO -.Xr fdisk 8 , -.Xr mount 8 , -.Xr newfs 8 , -.Xr swapon 8 -.Sh HISTORY -The -.Nm -utility appeared in -.Fx 5.0 -for ia64. -.Sh BUGS -The development of the -.Nm -utility is still work in progress. -Many necessary features are missing or partially implemented. -In practice this means that the manual page, supposed to describe these -features, is farther removed from being complete or useful. -As such, missing functionality is not even documented as missing. -However, it is believed that the currently present functionality is reliable -and stable enough that this tool can be used without bullet-proof footware if -one thinks one does not make mistakes. -.Pp -It is expected that the basic usage model does not change, but it is -possible that future versions will not be compatible in the strictest sense -of the word. -For example, the -.Fl p Ar count -option may be changed to a command option rather than a generic option. -There are only two commands that use it so there is a chance that the natural -tendency for people is to use it as a command option. -Also, options primarily intended for diagnostic or debug purposes may be -removed in future versions. -.Pp -Another possibility is that the current usage model is accompanied by -other interfaces to make the tool usable as a back-end. -This all depends on demand and thus feedback. diff --git a/sbin/gpt/gpt.c b/sbin/gpt/gpt.c deleted file mode 100644 index
