9 | .SH DESCRIPTION | |
10 | .I Disktab | |
11 | is a simple date base which describes disk geometries and | |
12 | disk partition characteristics. The format is patterned | |
13 | after the | |
14 | .IR termcap (5) | |
15 | terminal data base. Entries in | |
16 | .I disktab | |
17 | consist of a number of `:' separated fields. The | |
18 | first entry for each disk gives the names which are | |
19 | known for the disk, separated by `|' characters. The | |
20 | last name given should be a long name fully identifying | |
21 | the disk. | |
22 | .PP | |

24 | stored for each disk entry. | |
