.TH dbe 1 "ndbm(3) EDITOR" .SH NAME dbe \- Edit a ndbm(3) database .SH USAGE dbe [-m r|w|rw] [-crtvx] -a|-d|-f|-F|-s [ []] .SH DESCRIPTION \fIdbme\fP 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. .SH OPTIONS .IP -a List all entries in the database. .IP -c Create the database if it does not exist. .IP -d Delete the entry associated with the specified key. .IP -f Fetch and display the entry associated with the specified key. .IP -F Fetch and display all the entries whose key match the specified regular-expression .IP "-m r|w|rw" Open the database in read-only, write-only or read-write mode .IP -r Replace the entry associated with the specified key if it already exists. See option -s. .IP -s Store an entry under a specific key. An error occurs if the key already exists and the option -r was not specified. .IP -t Re-initialize the database before executing the command. .IP -v Verbose mode. Confirm stores and deletions. .IP -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. .SH SEE ALSO ndbm(3) .SH AUTHOR janick@bnr.ca
