cfgtool8

Usage

Overview

cfgtool manages a database of system configuration variables.

This should not be used to configure application type programs. Applications should use their own configuration file, because cfgtool is not portable.

Options

--init-repository directory

Create and initialize the repository. The directory is where the variables will be stored.

--get variable

Print value of variable to stdout.

--set variable value

Set value of variable to value The variable must exist.

--create variable value

Create a new variable and set its initial value. It is not an error for the variable to exist already. If it does, nothing happens; the value of the variable is not changed.

--destroy variable

Destroy a variable.

--is-true variable

Check whether variable exists and contains the value "yes". Don't output anything, just set the exit code.

--is-false variable

Opposite of --is-true: condition is true, if variable exists and contains the value "no" (actually, any value but "yes").

--lock

Lock variable repository. This is needed only when you need to lock the repository over several invocations of cfgtool. The repository is locked automatically, if it hasn't already been locked, but an implicit lock is also removed automatically. Avoid locking the repository for long periods of time.

--unlock

Unlock variable repository.

--locked

The variable repository was locked by an earlier process, but we own the lock. This prevents creating an implicit lock. If we created an explicit lock with --lock already, the implicit lock fails and then the whole operation fails. This must be the first option, except for --repository, if it used at all.

--list

List all existing variable names, one per line.

--exists variable

Test whether a variable exists.

--list-all

Output octet stream to stdout that contains all variables in repository.

--create-all file

Read octet stream from file file (use "-" for stdin) and create all missing variables.

--set-all file

Like --create-all, but also sets existing variables.

--repository directory

Use directory as the repository, instead of default location. Must be first.
