SDB(1)                      General Commands Manual                     SDB(1)

NAME
     sdb - simple key-value database baked by base64, json and arrays

SYNOPSIS
     sdb [-0dehjJv] -|db [-|=|==] [.file|expr ..]

DESCRIPTION
     SDB is a simple disk and memory string-based key-value database. It is
     based on CDB and uses

     -d          Decode stdin as base64 and prints to result to stdout

     -D          Find differences between two databases

     -C          Create the C and H files for a perfect hash implementation of
                 the contents of the given Sdb

     -G          Create the gperf file used by -C

     -e          Encode stdin in base64 and prints to stdout

     -h          Show help message

     -j          Indent JSON from stdin if no more arguments, otherwise dump
                 database as JSON.

     -J          Enable journaling

     -h          Show help message

     -v          Show version

EXAMPLES
     Some useful ways to run it:

     $ sdb -                           ; in memory database

     $ sdb test.db = < test.txt        ; create database from text file

     $ sdb test.db == a.txt b.txt      ; create database from text files in a
     single command

     $ sdb test.db                     ; dump contents of database

     $ sdb test.db a=b a               ; inline queries

     Append those quoted commands to 'sdb -' to test these sdb_query
     expressions:

     a=hello b=world a b    # hello world

     a=1 +a -a              # 2 1     ; key inc/dec

     a={"a":122} a:a=O a    # {"a":0} ; json set

     a={"foo":122} +a:foo   # 123     ; json increment

     []a=1,2,3,4,5 [?]a     # 5       ; count array

     []a=1,2,3,4,5 [0]a     # 1       ; get element

     []a=1,2 [0]a=X a       # X2      ; replace

     []a=1,2 [+0]a=0 a      # 012     ; prepend

     []a=1,2 [-1]a=3 a      # 123     ; append
