[CALUG] Looking for a tool

I'm looking for a UNIX tool to perform a specific set of functionality but I
dont know if there's anything out there that would do the trick.

I need a very small and light-weight tool that will allow me to me to
"insert" any number of data into a plain file and provide an interface for
performing that "insert" and also  "deletes" and "selects"  (using database

Confused yet?  :)

I'm working on an application that has a really small footprint and can't
afford to run another database intance or provide any more table space in
any of the already-existing ones.  I'm looking for something that will allow
me to implement a "/tmp"-like storage facility for miscellaneous data, but
in a single file.

EXAMPLE:   (using "STORE" as the storage filename)
  Say I'm running a session-enabled website and need such a tool for the
task I'm describing above.  Here's the kind of thing it would do...

$> sometool insert STORE "session id" "103847294837"
$> sometool insert STORE "number_users" "4"
$> sometool insert STORE "username" "foo"
$> sometool insert STORE "privs" "read/write"
$> sometool insert STORE "admin" "no"

$> SESSION=` sometool select STORE "session_id" `
$> echo ${SESSION}
$> USER=` sometool select STORE "username" `
$> echo ${USER}

I need something that's just that simple.  Just FYI...the session-enabled
website was stricly an example.  It is NOT what I'm working on.  It just
provided with a valid use-case for the tool.  The solution I'm looking for
can't be OS-dependent (so Linux or Solaris filesystem tricks in leu of a
tool are out the window).

Any ideas?  :)
