The -v option may be used to get a verbose description of the program's activities.
The -d option may be used to specify an alternate database. The default is given by the tbldbm configuration variable or by the MDBM parameter in the mmdftailor(F) file.
If no arguments are given to dbmedit, then the program goes into an interactive mode, and prompts the user for each command. Otherwise the arguments are taken as one command.
Commands in dbmedit refer to tables, keys, and values.
are hashed into the database using
(Tables that refer to domain name servers are not part of the database.)
The keys appear on the left side of the tables and the values on the
right side. In general, only the first occurrence of a value for a given
key/table pair is significant. For example, the table entries:
table1: key1: val1
table2: key1: val3
get hashed into the following database entries:
key1 table1 val1
key1 table2 val3
key1 table2 val4
key2 table1 val2
In the current implementation, the database is keyed on only the key, and table/value pairs are encoded in the data portion. This is likely to change but will not affect this or any other program.
The command lines in interactive mode are parsed using the standard MMDF string-to-argument routines so the same quoting and escape conventions are used. For example, if you want double-quotes or spaces in the value, they must be escaped with a backslash or the string must be quoted (for spaces).
The commands are:
All commands may be shortened to their first character only. If the wrong number of arguments is given to a command, a ``Usage:'' message is displayed. This program may be used while MMDF processes are running.
NOTE: All changes are made in real time; no temporary copy of the database is made while editing takes place.
