dbe − Edit a ndbm(3) database
dbe <database> [-m r|w|rw] [-crtvx] -a|-d|-f|-F|-s [<key> [<content>]]
dbme operates on ndbm(3) databases. It can be used to create them, look at them or change them. When specifying the value of a key or the content of its associated entry, \nnn, \0, \n, \t, \f and \r are interpreted as usual. When displaying key/content pairs, non-printable characters are displayed using the \nnn notation.
-a |
List all entries in the database. | ||
-c |
Create the database if it does not exist. | ||
-d |
Delete the entry associated with the specified key. | ||
-f |
Fetch and display the entry associated with the specified key. | ||
-F |
Fetch and display all the entries whose key match the specified regular-expression |
-m r|w|rw
Open the database in read-only, write-only or read-write mode
-r |
Replace the entry associated with the specified key if it already exists. See option -s. | ||
-s |
Store an entry under a specific key. An error occurs if the key already exists and the option -r was not specified. | ||
-t |
Re-initialize the database before executing the command. | ||
-v |
Verbose mode. Confirm stores and deletions. | ||
-x |
If option -x is used with option -c, then if the database already exists, an error occurs. This can be used to implement a simple exclusive access locking mechanism. |
