Creates or updates the search indexes of all tombs currently
open: enables use of the \fIsearch\fR command using simple word
patterns on file names. Indexes are created using updatedb(8) and
stored in an .updatedb file inside the tomb's root. To avoid indexing
patterns on file names. Indexes are created using mlocate updatedb(8) and

.B
.IP "--kdf \fI<method>\fR"
This will specify the KDF method to use for the tomb we're creating.
Please note that no stable release of tomb supports KDF; if you use it,
your tomb might be unusable with an older version of tomb.
You can specify parameters with --kdf=method:param. That is, for example,
\fI--kdf=pbkdf2:2.5\fR will use pbkdf2 with an itertime of 2.5 seconds
Supported methods are: pbkdf2, null
.B pbkdf2
is probably the most used kdf in security applications, so it's a good choice.
It accepts one parameter, that is the seconds it will take on this computer to
derive the key. The default is 1.
.B null
is just the same as not using --kdf at all: it will stick to the "classic"
behaviour

Please note that no stable release of tomb supports KDF; if you use it,

.IP "--kdf \fI<seconds>\fR"
Activate the KDF feature against dictionary attacks when creating a key: forces a
delay of \fI<seconds>\fR every time this key is used. Floating point values
are accepted, default is 1.
