![]() ![]() A monitor based on ReadDirector圜hangesW, a Microsoft Windows API that reports changes to a directory.A monitor based on File Events Notification, a Solaris/Illumos kernel API that reports file events.A monitor based on inotify, a Linux kernel subsystem that reports file system changes to applications.A monitor based on kqueue, an event notification interface introduced in FreeBSD 4.1 and supported on most *BSD systems.A monitor based on the File System Events API of Apple OS X.The list of monitors it currently supports is: It uses different kinds of monitors for different OS and can choose the appropriate one automatically, or allow one to specify which one to use and even pass custom platform-specific parameters to the respective monitor. Albeit with a much worse interface.Īfter searching the answers here and the ones at the other question mentioned as possible duplicate in the comments above, I think I'd go with fswatch since it is has cross-platform support. See the inotifywait answer for a better, and more powerful method of doing this. Note this isn't a failsafe mechanism because the inode could be recycled to a different file name entirely. It's after there is an operation on an inode it hasn't seen. Control of the TTY is not transferred the child process. entr waits for the utility to exit to ensure that resources such as sockets have been closed. A process group is created to prevent shell scripts from masking signals. SIGTERM is used to terminate the utility before it is restarted. As with the standard mode of operation, a utility which terminates is not executed again until a file system or keyboard event is processed. In this mode entr does not attempt to read from the TTY or change its properties. Files with names beginning with ‘.’ are ignored. This option also enables directories to be specified explicitly. -d Track the directories of regular files provided as input and exit if a new file is added.my_watch_dir | entr -dnr echo "Running trigger."Įcho. You can track a directory for new additions using while $(true) do You can install it with apt-get install entr ![]() ![]() entr was written to make rapid feedback and automated testing natural and completely ordinary. Uses kqueue(2) or inotify(7) to avoid polling. Note entr doesn't use polling giving it a huge advantage over many of the alternatives. Scli.UploadWithPath(evt.Using entr is the new way to do this (it's cross platform). If it is a WRITE event (new or modified file) let's upload it to the server We only connect to the server IF there are events to be processes Do we have at least 1 event to process? No Halt signal? Good, then let's acquire the list of pending event that we need to process When inside an endless cycle, it's always safe to check if we received a Halt signal at every cycle Let's sleep for 500 milliseconds at each cycle, to keep CPU usage low We need to keep checking events indefinitely, an endless cycle is what we need Watcher.WatchDir('C:\\TestFolder', false) Almost ready, let's tell the object what folder we want to monitor We can specify inclusion and exclusion filters (optional, not mandatory) We may choose *not* to be notified of certain events (useful to allow the file system to finish whatever operation is ongoing) Then we elect to delay notification by *at least* 300 seconds (5 minutes) First, let's create the file-system watcher ![]() Let's enable console feedback, in case we're running this script via the shell Here below you can see a well-commented AFT! script (in pure aftJS language) that shows you how to do all of the above the right way, taking all the above-mentioned circumstances into account: you may need to "delay" your uploads, because the OS (file-system) needs time to finish writing the local file before you can access it and upload it to the remote SFTP server.your SFTP server may (should) not allow your client to be always connected.detect when files are modified and upload themįurthermore, there are several other aspects to consider.detect when new files are created and upload them.That implies monitoring a local folder/directory on your computer's hard disk (or SSD), and: Let's say you have an SFTP server somewhere, and you want to use it as some form of "real-time backup".
