.SH OPERANDS
.sp
.LP
The following operands are supported:
.sp
.ne 2
.mk
.na
\fB\fIcmd\fR\fR
.ad
.sp .6
.RS 4n
Specifies whether to create, destroy, dump, or load the database, or to create
a stash file.
.sp
You can specify the following commands:
.sp
.ne 2
.mk
.na
\fB\fBcreate\fR \fB-s\fR\fR
.ad
.sp .6
.RS 4n
Creates the database specified by the \fB-d\fR option. You will be prompted for
the database master password. If you specify \fB-s\fR, a stash file is created
as specified by the \fB-f\fR option. If you did not specify \fB-f\fR, the
default stash file name is \fB/var/krb5/.k5.realm\fR. If you use the \fB-f\fR,
\fB-k\fR, or \fB-M\fR options when you create a database, then you must use the
same options when modifying or destroying the database.
.RE

.sp
.ne 2
.mk
.na
\fB\fBdestroy\fR\fR
.ad
.sp .6
.RS 4n
Destroys the database specified by the \fB-d\fR option.
.RE

.sp
.ne 2
.mk
.na
\fB\fBstash\fR\fR
.ad
.sp .6
.RS 4n
Creates a stash file. If \fB-f\fR was not specified, the default stash file
name is \fB/var/krb5/.k5.realm\fR. You will be prompted for the master database
password. This command is useful when you want to generate the stash file from
the password.

Causes the dump to walk the database recursively (\fBbtree\fR only). This might

corruption has occurred. In cases of such corruption, this option will probably
retrieve more principals than will the \fB-rev\fR option.

Loads a database dump from \fIfilename\fR into \fIdbname\fR. Unless the
\fB-old\fR or \fB-b6\fR option is specified, the format of the dump file is
detected automatically and handled appropriately. Unless the \fB-update\fR
option is specified, \fBload\fR creates a new database containing only the
principals in the dump file, overwriting the contents of any existing database.
The \fB-old\fR option requires the database to be in the Kerberos 5 Beta 5 or
earlier format ("\fBkdb5_edit load_dump version 2.0\fR").

Requires the database to be stored as a hash. If this option is not specified,
the database will be stored as a \fBbtree\fR. This option is not recommended,
as databases stored in hash format are known to corrupt data and lose
principals.
