Name
rehctaw
- Execute system commands according to file contents.
Description
rehctaw
watches contents of a file, and executes system commands
according to those contents. The commands, intervals, ... are provided
in a YAML configuration file which is also watched.
Example
The sample configuration file can be found under ./examples/
directory.
To use this example, type
$ cp ./examples/simple.yaml ./examples/mine.yaml
$ ./bin/rehctaw ./examples/mine.yaml
On another terminal, type for examples
$ echo foobar > /tmp/watcher
$ echo reload > /tmp/watcher
You will see some notifications from the output of rehctaw
command.
You can update the file ./examples/mine.yaml
. The program will use
new settings in the next check.

History
The idea comes from some Rails
framework. When a Rails
application
is running, you can quickly send a reload
signal to it, by touching
a file. See ChiliProject for an example.
I don't want to use inotify
, because that works at file system level
and it may cause some issues when the file is renamed.
