inoticoming - trigger actions when files hit an incoming directory

inoticoming [ global-options ] directory actions*

Inoticoming is a daemon to watch a directory with Linux's inotify framework and trigger actions once files with specific names are placed in there.

For example it can be used to wait for .changes files uploaded into a directory and call reprepro to put them into your repository.

Do not fork, but stay in the foreground and log to stderr.
After forking in the background, log to the specified filename instead of syslog.
Write the pid of the running instance into filename.
First search the directory for files already existing and process them with the given rules as if they just appeared. If files show up in this inital phase, they may be processed twice, but should never be missed. (Unless they are too many and the inotify queue overflows).

Each action description is an optional list of options for this action (which files to call it for, what directory to change into before executing it, ...), followed by the command and its arguments ended with a single ; as argument. Like:
inoticoming --foreground / --regexp ^v echo There appeared {} in the root directory. \; (Note that the \ before the ; is needed if and only if you calling it from a shell or anything else interpreting the ; on its own).

Only trigger this action, if the filename starts with the specified string.
Only trigger this action, if the filename ends with the specified string.
Only trigger this action, if the filename matches the specified regular expression.
Change into directory before executing the specified commands. (Note that since it is a well-behaved daemon, its working directory is / which will be inherited by all actions).
Redirect the command's output (stdout) to the logfile.
Redirect the command's error output (stderr) to the logfile.

This will call reprepro for every new .changes file. Note that giving {} as argument to processincoming (which inoticoming will replace with the filename) so that only that .changes file is processed and reprepro will not complain about a possible other yet incomplete .changes file is only available starting with reprepro version 2.2.2.

There is no handling of queue overflows yet.
