Berkeley DB Reference Guide: Dumping and Reloading
Loading text into databases
The db_load utility can be used to load random text into databases.
For example, the following command loads the standard UNIX /etc/passwd file into a database, with the login name as the key item and the entire password entry as the data item:
awk -F: '{print $1; print $0}' < /etc/passwd |
sed 's/\\/\\\\/g' | db_load -T -t hash passwd.db
Note that backslash characters naturally occurring in the text are escaped to avoid interpretation as escape characters by db_load.
