The slocate program uses a database format similar to, but not
quite the same as, GNU locate. The first byte of the database
specifies its security level. If the security level is 0,
slocate will read, match and print filenames on the basis of
the information in the database only. However, if the security level
byte is 1, slocate omits entries from its output if the
invoking user is unable to access them. The second byte of the
database is zero. The second byte is immediately followed by the
first database entry. The first entry in the database is not preceded
by any differential count or dummy entry. Instead the differential
count for the first item is assumed to be zero.
Starting with the second entry (if any) in the database, data is interpreted as for the GNU LOCATE02 format.
