dyndbget - read a record from a dynamic database
dyndbget key <dbfile
dyndbget searches for a record with key key in a dynamical database. The database must be readable (and seekable) on standard input.
Normally dyndbget prints the data
in the first record found matching key key and exits
0. If there is no record with the key B<key>, it exits
100 without printing anything.
If dyndbget encounters a read error, write error, or
database format error, it prints an error message and exits
111.
