DESCRIPTION
-----------
*rhdropbox* is a small daemon which can be used to watch one or more
directories for new files. When a new file is detected a external program.
Additional directories can be added to the damons watch list using a simple
unix socket based command interface.
OPTIONS
-------
The following options can be passed to the *rhdropbox* daemon:
*-D, --nodaemonize*::
This option instructs *rhdropbox* to run in foreground
instead of becoming a daemon which is the default.
*-u, --username <username>*::
run as this user. If no group is specified (*-g*) the default group of
the user is used. The default is to not drop privileges.
*-g, --groupname <groupname>*::
run as this group. If no username is specified (*-u*) this gets ignored.
The default is to not drop privileges.
*-C, --chroot <path>*::
Instruct *rhdropbox* to run in a chroot jail. The default is
to not run in chroot.
*-P, --write-pid <filename>*::
Instruct *rhdropbox* to write it's pid to this file. The default is
to not create a pid file.
*-L, --log <target>:<level>[,<param1>[,<param2>[..]]]*::
add log target to logging system. This can be invoked several times
in order to log to different targets at the same time. Every target
hast its own log level which is a number between 0 and 5. Where 0 means
disabling log and 5 means debug messages are enabled. +
The file target can be used more the once with different levels.
If no target is provided at the command line a single target with the
config *syslog:3,uanytun,daemon* is added. +
The following targets are supported:
*syslog*;; log to syslog daemon, parameters <level>[,<logname>[,<facility>]]
*file*;; log to file, parameters <level>[,<path>]
*stdout*;; log to standard output, parameters <level>
*stderr*;; log to standard error, parameters <level>
*-s|--command-sock <unix sock>*::
*rhdropbox* will listen on this unix socket for incoming commands. See next
chapter for details. The default is /var/run/rhdropbox/cmd.sock
*-x|--script <script>*::
The script which should be called when a new file is found. The following parameter
are passed to the scipt:
*<path>*;; the path to the folder containing the new file
*<filename>*;; the name of the new file relative to <path>
*<filesize>*;; the size of the file right after the event was received, this can be
used to determine wheter the file is complete. The script should
consider a file to be complete when it size doesn't change 3-5seconds
after the event got received.
COMMAND INTERFACE
-----------------
*rhdropbox* is listening for incoming commands at the unix socket speciefied by the
-s|--command-sock parameter. You can connect to this socket for example using
socat:
# socat UNIX-CONNECT:/var/run/rhdropbox/rhdropbox.sock STDIO
All commands have to end with '\n'. The following commands are supported:
*add <path>*::
Add a path to the list of directories to be watched. If the command succeds nothing
is returned. In case of an error a string of the form "Error: <reason>\n" is returned.
*remove <path>*::
Remove the path from the list of directories. If the command succeds nothing
is returned. In case of an error a string of the form "Error: <reason>\n" is returned.
*status*::
Returns the complete list of all directories from the wath list.
*listen [request|status|none]*::
Add the client to the status and or request listeners. When no parameter is passed to
this command the client listens to all messages.
A status listener gets a list of all directories whenever somebody else adds or removes
a path to the watch list. It also receives the list when somebody sends a status command
to the daemon.
A request listener also receives add and remove requests by other clients connected to
the command interface.
*log <text>*::
Print <text> to the logtargets of the daemon.
